MC3403PW

MC3403PW - Quad 1MHz 30V Op Amp | Texas Instruments

The Texas Instruments MC3403PW is a four-circuit general-purpose operational amplifier with a 1 MHz gain-bandwidth product, a 30 V maximum supply rating, and operation from -25°C to 85°C. The device is packaged in a 14-pin TSSOP, making MC3403PW suitable for compact analog signal-processing circuits that require four amplifiers in one package. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its two inputs while providing high input impedance, low output impedance, and stable operation with feedback. The MC3403 family combines four amplifiers with a low-power class AB output stage, true differential inputs, internal frequency compensation, and short-circuit protection. It sits within the operational-amplifier category as a general-purpose amplifier for instrumentation, control, and signal-conditioning systems. Key characteristics include four independent amplifier channels, a 1 MHz gain-bandwidth product, support for single and dual supplies, a true differential input stage, and internal frequency compensation. The -25°C to 85°C operating-temperature range supports industrial and commercial equipment when the surrounding system provides suitable thermal conditions. Its 14-pin TSSOP also reduces board area compared with four separate single-amplifier packages. Each amplifier is frequency compensated, so applications using voltage gain do not require an external compensation network. The class AB output stage is designed to support linear operation while the short-circuit-protection feature improves resilience in feedback-controlled circuits. Because the device is intended for general-purpose signal amplification, external precision resistors, compensation, output isolation, and protection components may still be needed when driving loads, extending bandwidth, or meeting application-specific noise and accuracy targets. Typical uses include low-frequency sensor conditioning, feedback-control loops, current-voltage signal conversion, analog summing and difference circuits, and four-channel buffer arrangements. The integrated quad structure is especially useful where several independent analog paths must fit on a compact PCB, such as industrial measurement modules, instrumentation interfaces, and embedded control systems. PCB layout should keep feedback resistors close to their corresponding amplifier pins, provide a solid ground return, and route high-impedance input nodes away from switching nodes. Decoupling capacitors should be placed close to the supply pins. Designers should verify output swing, input common-mode range, load capability, stability, and supply limits for the intended operating points using the manufacturer datasheet. This page combines the manufacturer product information, distributor product records, package details, application guidance, and available same-footprint comparison information to support component selection and board-level planning. It also identifies which electrical parameters require confirmation from the complete Texas Instruments datasheet before final design release.

MC34071D - 44V Single-Supply Operational Amplifier | onsemi
MC34071D

MC34071D - 44V Single-Supply Operational Amplifier | onsemi

The onsemi MC34071D is a single-supply operational amplifier designed for operation from 3.0 V to 44 V, with a 4.5 MHz gain-bandwidth product and a 13 V/µs slew rate. The device is packaged in an 8-pin SOIC and uses bipolar fabrication rather than JFET input devices. Its combination of high bandwidth, fast slew rate, and a wide supply-voltage range makes it suitable for industrial instrumentation, signal conditioning, data acquisition, and control systems that operate from elevated supply voltages. An operational amplifier is a high-gain differential amplifier used to amplify small input signals, buffer sensors, drive analog stages, and implement feedback-control networks. The MC34071 belongs to the broader hierarchy of operational amplifier, analog amplifier, signal-conditioning IC, and semiconductor. Although the MC34071 family can operate from split supplies, it is particularly suited to single-supply operation, which simplifies circuits whose signal reference is close to the lower supply rail. The family provides 4.5 MHz of gain-bandwidth product, a 13 V/µs slew rate, and fast settling time without using JFET device technology. The specified single-supply performance is defined at 5.0 V. The amplifiers are also functional at 3.0 V at 25°C, although bandwidth, slew rate, DC gain, and other parameters may change in that operating region. This distinction is important when designing at the minimum supply voltage. The bipolar process supports operation from a single 5.0 V supply or higher while accommodating input and output signals referenced toward ground. The wide 44 V maximum supply rating provides additional operating headroom for industrial systems while retaining the usual bipolar advantages of low input-voltage noise and accurate behavior around the output operating point. Designers should still use the manufacturer datasheet limits for input common-mode range, output swing, supply current, and stability with the selected gain and load. Typical uses include sensor-interface amplifiers, low-side current measurement, industrial control loops, audio and communications signal conditioning, active filtering, and general-purpose analog processing. Because the amplifier is optimized for single-supply operation, input and output signal levels must remain inside the datasheet common-mode and output-swing limits. Input common-mode limits depend on supply voltage and gain, so a signal that is valid at 5 V may not remain valid at 3 V. The main design consideration is supply headroom. Use decoupling close to the supply pins, verify that the selected feedback network remains stable at the intended noise gain, and check output-current capability for the load and output-voltage conditions. The MC34071 is not intended to replace a rail-to-rail input or output amplifier where signals exceed its specified common-mode or swing limits. This page combines verified manufacturer and distributor information with practical selection criteria, sourcing guidance, and verified same-package alternatives. It highlights where the MC34071D fits, where its non-rail-to-rail architecture requires careful signal-range review, and which replacement MPNs should be checked against the full datasheet before substitution.

MC34071P - 3-44V Single Operational Amplifier | onsemi | 8-DIP
MC34071P

MC34071P - 3-44V Single Operational Amplifier | onsemi | 8-DIP

The onsemi MC34071P is a single operational amplifier designed for single-supply operation from 3.0 V to 44 V, with an 8-pin DIP package. It is a general-purpose bipolar operational amplifier intended for instrumentation, buffering, signal conditioning, and control applications where a wide supply range and single-supply operation are useful. The device is specified for a 5.0 V single-supply condition while remaining functional down to 3.0 V at 25°C, although bandwidth, slew rate, and DC gain can change in that lower-voltage region. An operational amplifier is an analog integrated circuit that uses high-gain differential amplification to compare an inverting input with a non-inverting input. The MC34071P provides one amplifier circuit in an 8-DIP package, placing it within the hierarchy of operational amplifier, analog amplifier, and integrated circuit. Its single-supply capability simplifies circuits that operate from batteries, industrial control rails, test equipment, and other systems that do not provide a centered or negative supply. The MC34071P is associated with a 5 mV input offset voltage specification in distributor listings and uses quality bipolar fabrication in the onsemi MC33071, MC34071, and related family. The family includes dual and quad versions for designs that require multiple amplifier channels, but channel count and package differ when comparing those family members with the single MC34071P. The 8-DIP package is a through-hole package with a nominal 0.300-inch, 7.62 mm lead pitch, making it suitable for conventional PCB layouts and prototype boards. Typical uses include sensor signal conditioning, low-frequency active filtering, industrial instrumentation, audio and communications support circuits, and general voltage amplification. Because the amplifier can operate from a single supply, the input and output signal ranges must be checked against the supply rails. Designers should also account for input common-mode limits, output swing, bias-current effects, noise, stability, and the power dissipation produced by the selected supply voltage and load. The MC34071P is most appropriate when a through-hole single op amp is preferred and the design needs wide single-supply headroom. Its counterpart MC34071APG is the most directly identified cross-reference candidate in the available information. Before substituting any part, confirm the complete pinout, electrical limits, common-mode behavior, output swing, and stability requirements against the target circuit. This page consolidates the verified onsemi datasheet information, distributor package identification, and cross-reference findings into a practical component record. The key engineering distinction is not simply the 3.0 V to 44 V supply capability, but the combination of a single amplifier, bipolar implementation, through-hole 8-DIP construction, and the need to design the signal path around single-supply input and output limits.

MC34072D - 4.5 MHz Single Op Amp, 3-44 V | onsemi
MC34072D

MC34072D - 4.5 MHz Single Op Amp, 3-44 V | onsemi

The onsemi MC34072D is a single, general-purpose operational amplifier optimized for wide supply-voltage operation. It provides a 4.5 MHz gain-bandwidth product, a 13 V/µs slew rate, and operation from 3.0 V to 44 V in an 8-pin SOIC package. The MC34072D also supports fast settling to 0.1% within 1.1 µs and an input common-mode range that includes ground. An operational amplifier is a high-gain, active differential amplifier whose inverting and non-inverting inputs control an output voltage. Within the broader semiconductor hierarchy, an operational amplifier is an analog integrated circuit used for signal conditioning, current-to-voltage conversion, feedback control, filtering, and buffered drive stages. The MC34072 belongs to a family of single-supply, bipolar operational amplifiers designed to combine broad rail-voltage capability with relatively high bandwidth. The principal features of the MC34072D include 4.5 MHz gain bandwidth, 13 V/µs slew rate, 1.1 µs settling time to 0.1%, and a low 3.0 mV maximum input offset voltage for the A-suffix grade. It operates from 3.0 V to 44 V, and its input common-mode range includes the negative supply rail, which simplifies single-supply signal-chain design. Output swing extends from approximately -14.7 V to +14 V under the conditions listed by the manufacturer. The bipolar fabrication of the MC34071, MC34072, and MC34074 families supports the combination of wide bandwidth, high slew rate, and common-mode operation that extends to ground. This characteristic is particularly useful when signals remain close to the lower supply rail or when the amplifier must process bipolar sensor signals from a unipolar-powered acquisition circuit. Input bias current and noise specifications should be checked against the source impedance in the selected gain configuration. Typical uses include low-voltage sensor interfaces, industrial process-control loops, audio preamplifier stages, active filters, and general instrumentation. Its 3.0 V to 44 V operating range also makes it suitable for industrial systems that operate from a 5 V, 12 V, 24 V, or higher regulated rail. The device can be used where the required signal bandwidth remains below the amplifier's closed-loop bandwidth for the selected noise-gain setting. Designers should verify output-current capability, output-swing limits, input common-mode range, and stability at the intended gain and capacitive-load conditions. Keep feedback-loop layouts compact, place compensation or decoupling components close to the relevant pins, and avoid operating near the output-swing limits when driving low-impedance downstream loads. This page consolidates the MC34072D electrical characteristics, confirmed ordering variants, package information, and application guidance with comparison notes for engineers evaluating drop-in operational-amplifier alternatives.

MC34119D

MC34119D - Low-Power Class AB Audio Amplifier | NXP

The NXP MC34119D is a low-power, mono Class AB audio amplifier integrated circuit designed primarily for telephone equipment, including speakerphones. It operates from a 2 V minimum supply, supports a nominal range of 2 V to 16 V or ±1 V to ±8 V, and provides differential speaker outputs to increase usable output swing at low supply voltages. The device is supplied in an 8-pin SOIC package according to the distributor product listing. An audio amplifier is an integrated circuit that accepts a low-level analog audio signal and delivers enough current and voltage to drive a speaker or another acoustic transducer. The MC34119 belongs to the Class AB amplifier category, where the output transistors conduct during the signal cycle for improved efficiency than a continuously biased Class A design. Its telephone-oriented architecture supports portable and line-powered equipment where low supply voltage and compact implementation are important. The verified feature set includes a shutdown function, a single mono output channel, and differential speaker outputs. Differential outputs are particularly useful in telephone and speakerphone designs because they increase output swing into a differentially connected transducer. The manufacturer datasheet also identifies a 2.0 V minimum supply, allowing operation from low-energy source rails. The Class AB output stage is intended to balance output capability against power consumption in compact audio systems. MC34119D applications include telephone speakerphones, compact voice terminals, intercom equipment, and other low-voltage audio products. In these systems, the amplifier converts a microphone or line-level signal into a differential drive capable of energizing a small speaker. Designers should account for the external output-coupling capacitors shown in the manufacturer application circuit when connecting a speaker, and should verify the shutdown-control polarity and timing before sequencing the device. The most important design consideration is ensuring that the supply, input signal, output network, and speaker load remain within the limits defined by the manufacturer datasheet. Because the target is a legacy low-power audio amplifier, purchasing decisions should also account for lifecycle status, stock, and long-term sourcing rather than assuming availability from an active-production family. This page consolidates the verified package, supply-voltage, amplifier-class, shutdown, and differential-output information with practical selection guidance. It also distinguishes confirmed facts from parameters that require confirmation in the original MC34119 manufacturer datasheet, helping engineers evaluate MC34119D without relying on incomplete distributor summaries.

MC34119P - 2-16V Mono Class AB Audio Amp | NXP
MC34119P

MC34119P - 2-16V Mono Class AB Audio Amp | NXP

NXP MC34119P is a low-power, 1-channel Class AB audio amplifier IC designed for telephone equipment, including speakerphones, with a 2 V to 16 V supply range and differential speaker outputs in an 8-pin DIP package. It provides a practical solution where low supply voltage, low quiescent current, and efficient single-speaker drive are required. The available ordering information identifies the device as an NXP USA Inc. 8-PDIP mono audio amplifier. An audio amplifier IC is a semiconductor that accepts a small audio signal and delivers enough voltage and current to drive a loudspeaker or other audio transducer. A Class AB amplifier combines the low crossover distortion of class-A operation with improved efficiency compared with a continuously biased class-A stage. In the MC34119P, differential speaker outputs are intended to maximize output swing at low supply voltages, making the device especially relevant to compact telephone and communications equipment. The MC34119P operates from 2.0 V to 16 V, as documented in the retrieved manufacturer and distributor information. Its typical quiescent supply current is 2.7 mA for battery-powered designs, while shutdown reduces the typical quiescent current to 65 µA. A chip-disable input provides a direct means of placing the amplifier in its low-power state. These features allow the amplifier to remain useful when system power is constrained by a telephone line or battery source. Its architecture uses one Class AB output channel and differential speaker outputs rather than a conventional single-ended output arrangement. Differential drive can provide greater useful voltage swing into the speaker for a given supply, which is important at the 2 V minimum supply. This is a system-level advantage in speakerphone products where loudness and battery efficiency must coexist. Exact continuous output power, output impedance, gain settings, and distortion limits were not included in the retrieved source snippets and must be confirmed in the full manufacturer datasheet before final design sign-off. Typical uses include telephone speakerphones, telephone-line powered communications products, small intercom stations, compact voice monitors, and portable low-voltage audio equipment. The device is also suitable where standby consumption matters, because the shutdown function can isolate the amplifier from the active signal path. For these applications, the 2 V minimum operating voltage and differential output capability align particularly well with low-power, single-speaker systems. The primary design consideration is output-device and load compatibility. Engineers should verify speaker impedance, output power at the available supply voltage, thermal conditions, gain configuration, bypass capacitors, and shutdown logic against the complete MC34119 datasheet. Because the supplied text identifies an 8-DIP footprint but does not enumerate individual terminal functions, the pin assignment and exposed circuit details should not be inferred solely from this page. This product page consolidates the verified MC34119P package, voltage, topology, shutdown, and low-power information with practical application guidance, sourcing considerations, and honest drop-in replacement analysis. Its key value is separating confirmed MC34119P characteristics from unverified specifications and avoiding unsupported claims about substitutes that may require different EMI performance or pin behavior.

MC34184M - Low-Power Quad JFET Op Amp | onsemi
MC34184M

MC34184M - Low-Power Quad JFET Op Amp | onsemi

The onsemi MC34184M is a low-power, quad, JFET-input operational amplifier characterized by 210 uA of supply current per amplifier, a 4.0 MHz gain-bandwidth product, and a 10 V/us slew rate. Housed in onsemi's legacy MC34184M package, the device combines low input bias current with high input resistance for instrumentation, signal-conditioning, and low-frequency analog systems. A JFET-input operational amplifier is a voltage-amplifier device whose input stage uses junction field-effect transistors. This input architecture provides high input resistance and low input bias current while supporting relatively low supply-current operation. Within the power-management and analog-signal hierarchy, the MC34184M belongs to the operational-amplifier family and functions as a high-impedance buffer or closed-loop gain stage between sensors, transducers, analog switches, and downstream conversion or control circuitry. The primary performance characteristics of the MC34184M include a 4.0 MHz gain-bandwidth product, 10 V/us slew rate, and approximately 210 uA of supply current per amplifier. Its JFET input stage provides high input resistance, low input offset voltage, and high open-loop gain according to the Motorola MC34184 datasheet. These characteristics make the amplifier appropriate for precision current-voltage conversion, low-level signal amplification, active filtering, and feedback networks operating at low or moderate frequencies. The family architecture also supports practical instrumentation requirements because low input bias current reduces disturbance of high-impedance sources. A high gain-bandwidth product allows useful closed-loop bandwidth above the audio range when configured with conventional compensation and suitable external resistors. The 10 V/us slew rate improves handling of moderately fast signal edges, although the 4.0 MHz bandwidth places the device in the general-purpose precision-amplifier class rather than the high-speed operational-amplifier class. Typical applications include bridge-sensor signal conditioning, biomedical instrumentation, photodiode and phototransistor amplifiers, audio preamplification, active filters, sample-and-hold stages, and low-frequency closed-loop control loops. In each case, the amplifier should be evaluated for input common-mode range, output swing, noise, offset, stability, and supply compatibility under the actual operating conditions. Designers should verify the package dimensions, pin numbering, electrical limits, and common-mode range against the manufacturer documentation before layout. Input and feedback resistors must also be selected for low thermal noise and acceptable bias-current error. Bias compensation may be useful when source resistance is high enough that input bias current produces a material offset across the source impedance. This page organizes the core MC34184M electrical characteristics, practical application guidance, comparison parameters, and design considerations into one engineering-focused reference. It supports early architecture selection while preserving the need to verify production details, lifecycle commitments, and assembly-specific information with the manufacturer before releasing a design.

MC3437L - Hex Bus Receiver with Input Hysteresis | Motorola
MC3437L

MC3437L - Hex Bus Receiver with Input Hysteresis | Motorola

The Motorola MC3437L is a six-channel hexadecimal bus receiver with input hysteresis, supplied in a 16-pin CDIP package. The verified distributor listings identify the device as a 0/6 receiver and indicate a listed unit price of $2.6678 at LCSC as of 2026-10-23. The receiver is intended for digital bus-interface applications where noise immunity and signal conditioning are important. A bus receiver is an interface IC that converts a digital logic signal into a cleaner, standardized receiver output. The MC3437L belongs to the receiver and transceiver category, providing six receiver channels rather than a general-purpose analog function. Input hysteresis creates a defined transition region between low and high input levels, helping prevent output chatter when a noisy or slowly changing signal crosses the logic threshold. The verified search data specifically identifies the MC3437 as a Hex Bus Receiver with Input Hysteresis. The MC3437L ordering variant is shown by DigiKey as a 0/6 Receiver in a 16-CDIP package. The available source data does not provide detailed input thresholds, propagation delays, supply-voltage limits, output levels, temperature ratings, or absolute maximum ratings, so those values are not inferred here. Typical uses include digital control buses, computer peripheral interfaces, industrial equipment, communications equipment, and legacy systems where a six-channel receiver is useful. The CDIP package supports through-hole PCB assembly and may be preferred for repair, prototyping, and systems that use conventional DIP-compatible footprints. Actual signal integrity and system compatibility require checking the original manufacturer datasheet and the host bus voltage and timing. When replacing MC3437L, verify the exact pinout, logic polarity, supply requirements, propagation delay, and input thresholds before substitution. Do not assume that a similarly named transceiver or receiver is pin-compatible. The available source data does not establish lifecycle status, detailed electrical ratings, or a verified five-part drop-in replacement set.

MC3459P - Quad NMOS Address Line Driver | Motorola
MC3459P

MC3459P - Quad NMOS Address Line Driver | Motorola

The Motorola MC3459P is a quad NMOS address line driver, also described as a bipolar bus driver, packaged in a 14-pin DIP. The device contains four address-driver elements, each with a one-bit output, for driving address and control lines in older digital systems. According to the available distributor and datasheet listings, the MC3459P operates from a 5.25 V supply and is categorized as an address driver, bus driver, buffer, driver, receiver, and transceiver. A bus driver is an interface IC that strengthens digital signals so they can reliably travel between circuit boards, processors, memories, and peripheral devices. Within the logic-IC hierarchy, a bus driver sits below interface ICs and above general-purpose buffers. The MC3459P is specifically intended to drive multiple address lines in systems where the source device cannot directly provide the required output current or signal integrity. The main verified characteristics are a four-element architecture, one-bit output per element, a 5.25 V supply designation, bipolar bus-driver construction, and a 14-pin DIP package. The listings also identify the device as a Quad NMOS Address Line Driver. The exact output-current rating, propagation delay, output disable levels, input and output logic levels, operating temperature range, and absolute maximum ratings are not present in the supplied search data and therefore require confirmation from the manufacturer datasheet before release to production. The 14-pin through-hole package makes the MC3459P suitable for legacy computer, industrial-control, instrumentation, and data-acquisition equipment where motherboard-level bus routing and socketed DIP construction remain practical. Its four independent driver elements can be assigned to address or control lines when the system architecture requires buffered digital outputs. Modern designs may instead favor surface-mount bus-driver ICs with documented electrical limits and lifecycle guarantees. Engineers should confirm the pinout, enable-control polarity, and logic thresholds before substitution because the supplied distributor records identify the function and package but do not provide a complete pin table. Power-supply decoupling, unused-input handling, and signal-integrity checks should follow the manufacturer datasheet rather than assumptions based on generic 14-pin bus drivers. This page combines verified distributor descriptions, package information, sourcing records, and qualification data into a structured engineering reference. It also documents the remaining datasheet-dependent parameters and the limited cross-reference evidence so that engineers can distinguish confirmed facts from data requiring validation before procurement or PCB redesign.

MC3461L - Dual Current Sense Amplifier | Motorola | CDIP-16
MC3461L

MC3461L - Dual Current Sense Amplifier | Motorola | CDIP-16

The Motorola MC3461L is a dual current-sense amplifier in a 16-pin CDIP package, with two amplifier circuits for measuring current across low-value shunt resistors. The verified distributor data identifies the device as a high-speed NMOS/MECL current-sense amplifier, while detailed electrical limits, gain values, common-mode range, supply voltage, and temperature ratings are not included in the supplied records and therefore remain unconfirmed. Its instrumentation-amplifier classification places it among amplifier ICs used for power-conversion monitoring, motor control, battery management, and power-supply feedback. A current-sense amplifier is a specialized voltage-feedback amplifier that develops a measurable output voltage from the small differential voltage created by current flowing through a shunt resistor. The MC3461L contains two circuits, allowing one packaged device to monitor two independent current paths when the circuit board has sufficient isolation and the operating conditions of both channels are compatible. The 16-CDIP mechanical format is a through-hole ceramic dual in-line package intended for legacy industrial, instrumentation, and telecommunications equipment. The MC3461L's two-circuit architecture reduces component count compared with two separate single amplifiers, while its small shunt-generated differential signal supports compact sensing layouts. However, stable measurement depends on selecting an appropriate shunt, keeping Kelvin connections narrow and symmetrical, and observing the amplifier's common-mode and output limits. Because those numerical limits are absent from the verified excerpts, designers should consult the complete manufacturer datasheet before finalizing resistor values, gain configuration, supply rails, or production tolerances. The MC3461L is suitable for power-supply current monitoring, battery charge and discharge sensing, motor-control feedback, industrial process-control systems, and communications equipment. In these applications, the amplifier converts bidirectional or unidirectional shunt current into a voltage suitable for an ADC, controller, comparator, or protection circuit. The exact input polarity, output reference arrangement, and permissible common-mode voltage must be verified from the full datasheet before layout sign-off. A practical design begins by placing the shunt and amplifier in the same high-current path, routing the sense traces as a tightly coupled differential pair, and grounding the unused inputs or amplifier according to the manufacturer's recommended configuration. Decoupling capacitors should connect directly to the supply pins, and the output must remain within the device's verified output range. PCB creepage, clearance, copper heating, and Kelvin-trace geometry are as important as the IC choice in a high-current design. This page combines verified distributor identity and availability information with clearly marked engineering gaps, practical application context, and design guidance. It does not infer missing electrical specifications from the MC3461 family name, so procurement, electrical, and package decisions should be completed against the official datasheet and current authorized-channel inventory.

MC3476P1 Low-Cost Programmable Operational Amplifier | onsemi
MC3476P1

MC3476P1 Low-Cost Programmable Operational Amplifier | onsemi

The onsemi MC3476P1 is a low-cost, programmable operational amplifier designed for general-purpose analog signal conditioning. The device is associated with an 8-pin DIP package, and its core features include low power consumption, high input impedance, and a programmable operating point that allows engineers to adapt the amplifier to different bias and performance requirements. The MC3476P1 is therefore useful in applications requiring adjustable amplifier behavior rather than a fixed, conventional op-amp configuration. An operational amplifier is a voltage-controlled differential amplifier with very high open-loop gain. Its two inputs are the inverting input and non-inverting input, while the output is controlled by feedback in most practical circuits. The programmable family represented by the MC3476P1 adds a bias-current control function, allowing the operating current and associated performance to be adjusted externally. This makes the device more flexible than a fixed-bias amplifier when system designers need to balance power consumption, bandwidth, output drive, and signal-source loading. The MC3476P1 is described by its manufacturer as a low-cost selection of the MC1776 programmable operational-amplifier family. Its low power consumption is useful in battery-powered, portable, and low-power instrumentation systems. High input impedance helps reduce loading on high-impedance signal sources, which can help preserve signal amplitude and reduce input-stage interaction. The programmable bias architecture also gives designers a way to tailor performance after considering source impedance, gain, bandwidth, and acceptable supply current. Typical analog uses include sensor-interface stages, low-frequency instrumentation, buffer and gain stages, active filters, and signal-conditioning blocks in industrial or embedded control systems. The device can be used where a general-purpose amplifier is sufficient and adjustable operating current is valuable. Designers should review the manufacturer datasheet for guaranteed input-voltage range, output-swing limits, supply-current ranges, gain-bandwidth behavior, offset voltage, input bias current, and package details before finalizing a design. A key implementation consideration is the connection of the programmable-bias circuitry. Incorrect resistor values, unsuitable bypassing, or operation outside the specified supply and common-mode ranges can reduce stability or prevent expected output behavior. Keep the input network and feedback components close to the device, use a stable bypass capacitor at the supply pins, and verify noise, settling time, and output-swing requirements with the actual source impedance and load. This page combines the manufacturer-linked product identity, documented package information, application guidance, and practical design considerations for engineers evaluating the MC3476P1. Because the exact electrical limits and pin assignments are not reproduced in the cited search results, consult the original MC3476P1 datasheet for authoritative values before schematic release, PCB layout, or production qualification.

MC3486D - 4-Channel RS-422/423 Receiver | Texas Instruments
MC3486D

MC3486D - 4-Channel RS-422/423 Receiver | Texas Instruments

The Texas Instruments MC3486D is a monolithic quadruple differential line receiver with four independent differential inputs, TTL-compatible 3-state outputs, and single 5 V operation in a 16-pin SOIC package. It is designed for ANSI TIA/EIA-422-B and TIA/EIA-423-B and ITU V.10 and V.11 interfaces. The four receivers convert balanced differential line signals into digital logic levels, making the device suitable for multi-channel industrial, communications, and data-acquisition systems. A differential line receiver is an interface IC that rejects common-mode noise and extracts a logic decision from two complementary conductors. The receiver belongs to the line-interface hierarchy: differential receiver → RS-422/RS-423 interface IC → digital interface IC → semiconductor. This category is used where transmitted logic signals must cross cables or noisy interconnects without allowing voltage offsets and interference to corrupt the receiving logic. The MC3486 provides four independent channels, a shared enable control for the output states, and TTL-compatible outputs. Its 3-state capability permits each receiver output to enter a high-impedance state when the interface is not being selected. Fast transition times support reliable signaling, while the single 5 V supply simplifies connection to conventional TTL and CMOS-compatible system logic. The MC3486D is particularly suited to balanced communication links using RS-422 or RS-423 signaling. It can terminate long or electrically noisy interconnects at the receiving end, while its differential input structure provides noise immunity compared with a single-ended receiver. The device is also intended for use with the MC3487 quadruple differential line driver, creating matched transmit and receive channels.

The receiver is intended for industrial-control, data-communication, and instrumentation interfaces where multiple balanced lines must be converted into digital logic levels. A differential line receiver is an interface IC that compares two complementary conductors, rejects common-mode voltage and noise, and converts the resulting logic state into a single-ended digital output. In the signal-processing hierarchy, the MC3486NS belongs to the receiver family within line-driver and receiver interface ICs, which ultimately fall under interface ICs and semiconductors. Its four channels allow one package to replace four discrete differential receiver sections while preserving a standardized balanced-line interface. Key features include four differential receivers, TTL-compatible outputs, selectable 3-state output operation, operation from a single 5 V supply, and compatibility with TIA/EIA-422-B, TIA/EIA-423-B, ITU V.10, and ITU V.11 requirements.

MC3487D - 4-Channel RS-422 Driver | Texas Instruments | 5V

The Texas Instruments MC3487D is a quadruple differential line driver with four independent drivers, a 5 V single supply, and a 16-pin SOIC package. Its differential outputs meet ANSI TIA/EIA-422-B and ITU Recommendation V.11 requirements, while the tri-state outputs permit a high-impedance state for bus management. Each channel uses a TTL-compatible buffered input to reduce loading, making the device suitable for RS-422 point-to-point and multidrop communications. A differential line driver is an interface IC that converts a single-ended logic signal into a balanced pair of differential signals. In the hierarchy of electronic components, it belongs to the interface IC family, within communication and transceiver devices. Differential signaling improves noise immunity by rejecting common-mode noise and allows reliable data transmission over longer cable runs than ordinary single-ended digital logic. The MC3487D provides four driver channels rather than a full transceiver, so it does not receive differential data. The output-enable function controls the output state, allowing connected drivers to be disabled when they are not active. This is useful in systems that share a bus or require controlled output states. Power-up and power-down protection are also identified in the manufacturer documentation. Typical uses include industrial RS-422 links, data acquisition systems, test equipment, instrumentation, and multi-channel communication links. The 5 V supply operation simplifies interface design in legacy and industrial systems where the host logic uses a 5 V rail. Because it is a driver-only device, the system designer must provide the receiving circuitry and define cable termination, grounding, and enable-control behavior. The main design considerations are signal integrity, cable length, supply decoupling, and output-state control. Differential pairs should be routed with consistent geometry and appropriate grounding. The output-enable signals should be controlled during reset so that multiple channels do not contend on a shared bus. The device is intended for surface-mount assembly in the 16-pin SOIC package.

MC3487DE4 - Quad RS-422 Line Driver | Texas Instruments

Texas Instruments MC3487DE4 is a quadruple differential line driver with four independent outputs, a single 5 V supply, and a 16-pin SOIC package. Each channel receives a TTL-compatible input and produces a balanced differential signal designed to meet ANSI TIA/EIA-422-B and ITU Recommendation V.11 requirements. The MC3487DE4 is suitable for industrial control, instrumentation, data acquisition, telecom, and test-equipment systems that transmit digital signals reliably over longer cable distances than single-ended logic permits. A differential line driver is an interface IC that converts one logic input into two complementary outputs. This arrangement rejects much of the common-mode noise picked up by a cable, improving signal integrity in industrial environments. The MC3487 belongs to the broader interface-IC hierarchy: line driver → differential line driver → digital interface IC → semiconductor. Its four channels allow one package to drive four separate balanced links while sharing a common supply and ground reference. Key features include four independent differential drivers, TTL-compatible buffered inputs, three-state output capability, fast transition times, and high-impedance inputs. Power-up and power-down protection helps prevent uncontrolled driver activity during supply changes. The buffered inputs reduce input loading, allowing the device to operate reliably with standard TTL and CMOS control logic when voltage-level compatibility is confirmed in the system design. Technically, the MC3487 is a single-supply RS-422-focused transmitter rather than a complete bidirectional transceiver. It does not include receiver channels. Systems requiring two-way communication normally combine this driver with a separate differential receiver, such as a compatible RS-422 receiver IC. The differential outputs should be routed as a matched pair to preserve signal polarity and minimize common-mode conversion along the cable. Typical applications include RS-422 test equipment, industrial automation links, programmable logic controller interfaces, data-acquisition systems, servo or motor-control signaling, point-to-point computer peripherals, and instrumentation. Designers should use twisted-pair wiring, provide a stable 5 V supply, connect the common ground reference, and account for the voltage drop and noise margin of the selected cable length. The principal design consideration is ensuring that every connected receiver recognizes the driver’s differential output levels and that unused outputs are handled according to the manufacturer’s recommendations. PCB placement should minimize the distance between the interface connector and driver outputs, while avoiding noisy switching-current paths near the differential traces. This page combines device specifications, sourcing guidance, drop-in alternatives, and practical interface-design notes for engineers evaluating the MC3487DE4.

MC3487J

MC3487J - Quad Differential Driver, 5V, DIP-16 | Texas Instruments

The Texas Instruments MC3487J is a quadruple differential line driver operating from one 5 V supply and packaged in a 16-pin dual-in-line package. It provides four independent differential outputs for ANSI TIA/EIA-422-B and ITU Recommendation V.11 interfaces. Each channel uses a buffered TTL-compatible input to reduce loading, while 3-state outputs support shared-bus control. The MC3487J is a through-hole military-temperature-grade DIP-16 option. A differential line driver is an interface IC that converts a TTL-compatible logic signal into a balanced pair of differential signals. The balanced topology helps reject common-mode noise and supports reliable point-to-point data transmission. In the interface hierarchy, the MC3487J belongs to the line-driver family and implements the transmit side of a differential communications link. Its intended counterpart is the MC3486 quadruple line receiver. The MC3487 contains four independent channels, a single 5 V supply architecture, high-impedance inputs, and 3-state outputs. The official product description identifies these features as supporting reduced input current and minimized loading. Power-up and power-down protection are also listed in the device literature. The verified distributor data identifies the MC3487J as a military-temperature-grade, through-hole, 16-terminal rectangular DIP, but does not provide all timing, output-current, or temperature limits. Each output is intended for a balanced differential connection rather than a single-ended RS-232-style signal. Because outputs can enter a high-impedance state, the device can participate in bus-direction or driver-enable control when the system requires it. Designers must still account for the differential network, termination strategy, unused inputs, and the voltage levels required by the connected receiver. Exact propagation delay, transition time, output impedance, and common-mode limits require the manufacturer datasheet. Typical uses include industrial instrumentation, computer peripherals, point-to-point data links, test equipment, and legacy communications interfaces. In a transmitter design, the MC3487J sits between a TTL/CMOS-compatible control circuit and a balanced cable or board trace. The receiving end can use an MC3486 or another compatible differential receiver. Keep the driver close enough to the connector or transceiver boundary that unbalanced stub lengths remain short and the cable transition is clean. The principal design consideration is verifying the 5 V rail and every connected differential input against the device electrical limits before layout release. Decoupling should follow the manufacturer guidance, and unused inputs must not be left in an undefined state if they can affect system behavior. The MC3487J is appropriate when a legacy, balanced, TTL-driven interface is required and a through-hole DIP-16 assembly is preferred over a surface-mount package. This page consolidates the verified Texas Instruments product description, manufacturer datasheet link, package information, distributor price indication, and application-oriented design guidance. It also separates verified facts from parameters that still require confirmation in the datasheet, helping engineers make an evidence-based sourcing decision.

MC3487N - 4-Channel RS-422 Differential Driver | Texas Instruments

The Texas Instruments MC3487N is a four-channel differential line driver operating from a single 5 V supply in a 16-pin dual-in-line package. It provides one differential driver per channel, TTL-compatible buffered inputs, and three-state outputs for interface bus control. The device is designed to meet ANSI TIA/EIA-422-B and ITU Recommendation V.11 requirements, making it suitable for point-to-point and multidrop digital communication links. Its bipolar implementation and high-impedance inputs help reduce loading on source logic. The MC3487 is intended for use with compatible differential receivers such as the MC3486 family, while its four independent channels allow several differential signals to be transmitted on one board. The 16-pin PDIP package supports conventional through-hole PCB assembly and straightforward socket or leaded prototyping. An RS-422 differential line driver is a digital interface component that converts a single-ended logic input into a balanced differential output. Differential signaling uses two conductors carrying complementary signals, allowing common-mode voltage and ground-potential differences to be rejected by the receiver. A multi-driver such as the MC3487 consolidates four such output channels in one device, reducing component count and simplifying control in industrial, communications, instrumentation, and embedded systems. The MC3487N is therefore positioned within the hierarchy of logic ICs, interface ICs, line drivers, and communication transceivers. The principal verified features are four independent differential drivers, a single 5 V operating supply, TTL-compatible input buffering, and three-state outputs. The output-enable function is useful when several drivers share a bus or when a system must place an external line into a high-impedance state. Fast transition times support digital data-transfer applications where edge distortion must be controlled. Power-up and power-down protection helps prevent unintended line activity during supply transitions, an important consideration in multi-node equipment. The manufacturer describes the device as interchangeable with compatible RS-422 driver implementations, but system designers should still verify timing, load, protection, and supply requirements for the exact implementation. The MC3487N is a bipolar interface IC rather than a power semiconductor or a modern low-voltage transceiver. It is intended for legacy and established differential-bus designs where 5 V logic, through-hole assembly, and standard RS-422 electrical behavior are priorities. Because the verified data supplied for this page does not include detailed propagation-delay, output-current, input-current, temperature-range, or package-dimension tables, those values are marked as data needed rather than inferred. This preserves separation between verified manufacturer information and engineering estimates. Typical applications include industrial control interfaces, point-to-point serial links, test equipment, data-acquisition systems, peripheral communication, and legacy computer or industrial buses. In a point-to-point link, the MC3487N transmits four complementary differential pairs to a remote receiver. In a multidrop arrangement, the three-state outputs permit driver tri-stating, although cable length, topology, termination, and fault tolerance still require system-level validation. The 16-pin PDIP package is convenient for through-hole designs and prototypes but occupies more board area than a surface-mount equivalent. When laying out a board, place the device near the line-driver outputs and provide a solid ground reference. Keep differential traces coupled and matched in length where practical, provide receiver termination appropriate to the selected RS-422 topology, and leave protection-network space for surge or ESD requirements. Do not assume that a logical replacement preserves all legacy timing and fail-safe behavior; compare the complete data sheets and validate the assembled interface. This page synthesizes verified source links, interface guidance, and comparison structure for engineers evaluating the MC3487N.

It is designed to meet ANSI TIA/EIA-422-B and ITU Recommendation V.11 requirements, making it suitable for balanced digital data links. Each driver accepts a TTL-compatible input through a buffered input that reduces loading, while the differential outputs support reliable transmission over longer cables in noisy industrial environments. The MC3487NS provides three-state outputs, fast transition times, high-impedance inputs, and power-up and power-down protection. A differential line driver is a signal-conditioning interface that converts one logic input into two complementary outputs for a balanced transmission line. This differential signaling method improves noise immunity because the receiver detects the voltage difference between the two conductors rather than relying on one conductor relative to ground. In the hierarchy of electronic components, the MC3487NS is a line-driver IC, a differential interface IC, and a member of the broader interface IC and semiconductor categories. The principal electrical benefit is the combination of four differential channels in one package, allowing multi-channel data links to share a compact circuit footprint. The single 5 V supply simplifies power design, while TTL-compatible inputs allow direct connection with common digital logic families. Three-state outputs permit a connected driver to present a high-impedance state when it is not actively driving a bus, which is useful in systems requiring controlled driver enable and disable behavior. The MC3487NS is commonly paired with the MC3486 quadruple differential line receiver. It can also be used in industrial control links, instrumentation interfaces, test equipment, data acquisition systems, and communications equipment where a point-to-point or multidrop balanced line must be driven from TTL logic. The fast output transition times support higher data rates while maintaining the differential signaling characteristics expected by RS-422-class systems. Designers should verify the complete pinout and logic levels in the manufacturer datasheet before layout because the supplied web excerpts do not expose the individual pin names. The 16-pin surface-mount package should be treated as a differential signaling device: route the driver outputs as a matched pair, minimize stub lengths, provide a continuous ground reference, and confirm cable termination requirements for the selected data rate and topology.

MC3488AD

MC3488AD - Dual EIA-423/EIA-232D Line Driver | onsemi

onsemi MC3488AD is a dual single-ended line driver designed for EIA-423 and EIA-232D signals, with compatibility also identified for CCITT X.26, X.28, and Federal Standard FIDS1030. The device is intended for applications requiring signal wave shaping when the output load resistance exceeds 450 ohms. It is supplied in an 8-pin SOIC package. Its adjustable output slew rate spans from 1.0 V/µs to 100 V/µs, allowing the transition rate to be adapted to the connected line and receiver. A line driver is an interface circuit that converts digital logic signals into transmission-line-compatible signals for communication links. The MC3488AD belongs to the RS-232 and RS-422 interface IC category, where it provides single-ended output stages for driving external cables or receiver circuits. Compared with a general-purpose logic buffer, its purpose-built driver architecture controls edge transitions and supports the voltage, loading, and waveform requirements associated with established EIA and CCITT communication specifications. The MC3488AD provides two driver channels in one 8-pin SOIC package, reducing the component count in designs requiring more than one transmission-channel output. Its principal documented features include adjustable slew rates from 1.0 V/µs to 100 V/µs, operation with output load resistance greater than 450 ohms, and support for EIA-423, EIA-232D, CCITT X.26, X.28, and Federal Standard FIDS1030. These characteristics make the part relevant to legacy data communications, industrial control links, and equipment interfaces that still use specified single-ended line-driver networks. Slew-rate control is the main technical design variable. A slower edge reduces high-frequency content and ringing but increases transition time, while a faster edge supports higher data throughput at the cost of greater electromagnetic-interference potential and sensitivity to load or termination details. Because the MC3488AD permits adjustable output slew rates, the correct configuration should be selected against the cable length, data rate, receiver thresholds, grounding arrangement, and system EMC requirements rather than chosen solely from a standard data-rate label. Typical uses include industrial serial interfaces, legacy controller peripherals, data-acquisition equipment, and communications systems that require two single-ended line-driver outputs. A board design may pair the MC3488AD with a compatible line receiver such as MC3487DR, a multi-driver interface such as MC3486DR, or a logic interface such as P82B96DR. The output network must be checked against the applicable interface standard because the presence of a compatible logic-side pinout alone does not establish complete system-level interchangeability. When laying out the circuit, keep the output drivers close to their connector or interface-network entry points, provide a stable return path, and verify the selected slew rate against the actual load. Do not infer the complete electrical performance from the EIA references alone; supply voltage, output levels, propagation delay, input compatibility, and absolute maximum ratings must be confirmed in the manufacturer datasheet before production release. This page consolidates the verified manufacturer-document information, exact source links, interface standards, package data, sourcing context, and drop-in comparison candidates for the MC3488AD. It also separates documented facts from values that still require schematic-level verification, helping engineers evaluate this legacy line-driver IC without relying on incomplete distributor summaries.
