SN75189N - Quad RS-232 Line Receiver | Texas Instruments
Texas Instruments SN75189N is a quadruple RS-232 line receiver IC with four independent receive channels, a 4.5 V to 5.5 V single-supply range, and a 14-pin PDIP package. Each receiver includes input hysteresis and a response-control terminal that supports threshold shifting or input-noise filtering. Designed for data-terminal and data-communication equipment interfaces, the device targets the receiver side of TIA/EIA-232-F systems. An RS-232 line receiver is an interface-circuit category that converts bipolar serial data signals into logic-level signals for digital equipment. The SN75189N belongs to the broader line-receiver, interface-IC, and semiconductor hierarchy. Its four-channel arrangement allows one package to receive four independent data signals while sharing a common supply and ground. This reduces component count in multi-channel equipment, test systems, industrial controllers, and computer interfaces. Key features include four integrated receivers, a 5 V nominal operating supply, input hysteresis for improved noise immunity, and 7 kΩ input resistance. The response-control function can shift receiver thresholds or introduce input filtering by connecting suitable resistance and capacitance to the CONT terminals. These controls provide flexibility when the received signal levels, cable environment, or system noise conditions differ from standard receiver defaults. The monolithic low-power Schottky implementation combines the four receivers in one package while retaining separate response-control inputs. The input signal range is specified as 30 V, which accommodates the voltage excursions associated with RS-232 signaling. A 7 kΩ input resistance limits loading on the transmitting side, while the receiver logic output provides a convenient interface to TTL or CMOS equipment. Typical applications include multi-channel RS-232 data acquisition, industrial serial-port equipment, test and measurement systems, terminal interfaces, and embedded controllers requiring more than one receive function. Using four receivers in one package simplifies routing and reduces the number of interface ICs, but the system designer must still account for correct signal grounding, cable transients, unused-channel handling, and adequate supply bypassing. For PCB implementation, place the device in accordance with the manufacturer's pin-description table and keep input and supply paths compact. Decouple the 5 V rail close to the supply pin, provide a low-impedance ground connection, and route each receiver input away from switching nodes. Confirm that every unused output has a defined downstream state and that CONT pins are configured for the intended threshold and filtering behavior. This product record combines the manufacturer's device information, package and interface details, an RS-232-oriented engineering description, drop-in replacement analysis, comparison parameters, and practical layout guidance. It is intended to support component selection and board-level implementation without obscuring the distinctions that must be checked before approving a substitution.
SN75HVD1176 - 40Mbps PROFIBUS RS-485 Transceiver | Texas Instruments
The Texas Instruments SN75HVD1176 is a half-duplex PROFIBUS RS-485 transceiver that meets or exceeds the requirements of ANSI TIA/EIA-485-A for differential data transmission across twisted-pair networks, signaling at up to 40 Mbps. It is offered in an 8-pin SOIC package and integrates a differential driver, differential receiver, and bus-idle fail-safe circuitry on a single die, with a 1/5 unit load that permits up to 160 nodes on a single bus. An RS-485 transceiver is a physical-layer interface IC that converts a single-ended TTL/CMOS logic signal into a robust differential voltage on a twisted-pair bus, and vice versa. RS-485 belongs to the EIA/TIA-485 standard family and is widely used in industrial multipoint networks because it supports long cable runs, high noise immunity, and multiple node addresses. PROFIBUS (Process Field Bus, IEC 61158/EN 50170) is an industrial fieldbus protocol that imposes tighter symmetry, rise/fall time, and voltage-swing requirements on the transceiver than generic RS-485. SN75HVD1176 targets that PROFIBUS envelope while remaining backward-compatible to RS-485, sitting in the hierarchy: PROFIBUS transceiver -> RS-485 transceiver -> differential line transceiver -> physical-layer IC -> wired communication IC -> semiconductor. Key features include signaling rates up to 40 Mbps, 1/5 unit load (up to 160 nodes), low bus capacitance of 10 pF maximum, thermal shutdown protection, short-circuit-protected bus pins, and an industrial -40C to +85C operating temperature range. The differential output voltage exceeds 2.1V into a 54 ohm load, comfortably meeting the PROFIBUS VOD minimum while leaving margin for cable loss. Driver enable (DE) and receiver enable (RE) pins support direction control and half-duplex arbitration. The device uses a bipolar CMOS-DMOS process that integrates ESD cells, bus-tap protection, and a precision differential comparator on the receive path. Internal fail-safe biasing forces a deterministic logic-high on R when the bus is idle, shorted, or open, eliminating the need for external fail-safe resistors on most networks. The 10 pF maximum bus pin capacitance helps maintain signal integrity at 40 Mbps on long stubs and many-node buses. Typical applications include PROFIBUS-DP master and slave nodes, RS-485 industrial backbones, factory-floor PLC I/O expansion, motor-drive isolated communication channels, building automation networks, and any 5V industrial multipoint data link that must interoperate with PROFIBUS DP/PA gateways or legacy RS-485 masters. When designing with this part, place a 100 nF decoupling capacitor within 2 mm of VCC and provide a low-impedance ground return for bus-pin ESD currents. Maintain 100 ohm characteristic-impedance twisted pair and use fail-safe biasing only when the standard internal biasing does not meet the application idle-state requirement. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, including same-brand family alternatives and cross-brand pin-compatible equivalents verified against the TI datasheet.
SN75LVDS84ADGG - FlatLink 21:3 LVDS Transmitter | Texas Instruments
The Texas Instruments SN75LVDS84ADGG is a FlatLink™ LVDS serializer transmitter that compresses 21 bits of parallel LVTTL data into 3 LVDS data pairs plus 1 LVDS clock pair, supporting throughput up to 196 MBps (MegaBytes per second). Packaged in a 48-pin TSSOP (DGG) with an operating temperature range of 0°C to +70°C, it is purpose-built for graphic-controller-to-display interconnects such as SVGA, XGA, and SXGA LCD panels. An LVDS serializer (also called an LVDS transmitter, FlatLink, or channel link) is a parallel-to-serial interface IC belonging to the broader LVDS (Low-Voltage Differential Signaling) family of interface ICs. The category hierarchy is: LVDS serializer → LVDS interface IC → display interface → signal conditioning IC → interface IC. LVDS transmits data as a small differential current (~3.5 mA) across a 100 Ω termination, producing low-EMI, low-power, high-speed point-to-point links over twisted-pair cabling or PCB traces. Key features of the SN75LVDS84ADGG include four integrated LVDS line drivers, three 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer that multiplies the parallel clock by 7 for serial bit-clock generation, and 21 LVTTL data inputs plus a clock input. The on-chip PLL generates the high-speed serialization clock from a low-frequency reference, eliminating the need for an external high-frequency oscillator. The device is typically paired with an SN75LVDS82 / SN75LVDS86A receiver at the display end. Architecturally, the SN75LVDS84A uses a PLL-based 7:1 serialization scheme per channel. Each LVTTL data bit is sampled on the rising edge of the parallel clock, latched into a shift register, then clocked out at 7× the input clock frequency onto its differential pair. This architecture achieves aggregate throughput of 196 MBps while consuming only about 100 mW typical power from a single 3.3 V supply. The receiver counterpart (SN75LVDS82/SN75LVDS84A pair) reverses this process, recovering the parallel data and clock from the three LVDS data pairs. Typical applications include notebook LCD panels, desktop monitor controllers, industrial flat-panel displays, and point-of-sale terminals using XGA/SXGA TFT panels. The TSSOP-48 footprint is the de-facto standard for FlatLink chipsets, enabling drop-in compatibility across the SN75LVDS84A family and most third-party clones. The SN65LVDS84AQ variant provides the same functionality with automotive-grade qualification (AEC-Q100) for in-vehicle display systems. When designing with this device, pay close attention to PCB layout: the four LVDS differential pairs should be routed as 100 Ω-impedance matched pairs with intra-pair skew under 50 ps, and the LVTTL bus should be length-matched to within ±1 inch to avoid setup/hold violations at the rising-edge sample point. A 100 Ω termination resistor across each LVDS pair at the receiver end is mandatory for proper signal swing.
SN75LVDS84ADGGR - 21:3 FlatLink LVDS Transmitter 48-TSSOP | TI
The Texas Instruments SN75LVDS84ADGGR is a 21-bit single-ended LVTTL to 3-channel LVDS FlatLink transmitter in a 48-pin TSSOP (DGG) package. It serializes 21 bits of parallel data plus clock into three balanced-pair LVDS data channels plus one LVDS clock, supporting throughput up to 196 MBps (megabytes per second) over distances suitable for SVGA/XGA/SXGA LCD flat-panel interconnects. A FlatLink transmitter is a parallel-to-serial LVDS serializer designed to reduce cable and connector pin count while maintaining high-speed signaling. Within the device, three 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer, and four LVDS line drivers serialize and convert single-ended LVTTL data on the controller side to differential LVDS pairs on the display side, yielding very low EMI compared to wide parallel TTL buses. Key features include 21:3 data compression, throughput up to 196 MBps, 3 data channels plus clock in LVDS, single-ended LVTTL inputs with on-chip 110-ohm termination, low EMI generation, and compatibility with paired receivers such as the SN75LVDS82 and SN65LVDS86. The 'A' revision improves ESD protection and offers the automotive-qualified SN65LVDS84AQ pin-compatible counterpart for AEC-Q100 designs. Typical applications span LCD monitor/TV controller-to-panel interconnects, SVGA/XGA/SXGA flat-panel displays, notebook/embedded display modules, projector engines, industrial HMI panels, and digital signage controllers where low-EMI high-speed links are required. It is commonly paired with the SN75LVDS82 receiver on the TCON side. Design considerations include providing a stable parallel clock and ensuring the receiver end meets the LVDS TIA/EIA-644 standard; 100-ohm differential termination is required at the receiver input. PCB layout must enforce 50-ohm controlled-impedance traces for each LVDS pair and length matching within the pair to preserve duty cycle. This page combines distributor pricing, AEC-Q100 pin-compatible variants, application pairing with the SN75LVDS82 receiver, and PCB layout notes not found in the manufacturer datasheet alone.
SP208CA-L/TR - 5V RS-232 4-Driver/4-Receiver Transceiver | MaxLinear
The MaxLinear SP208CA-L/TR is a 5V-powered RS-232 line transceiver integrating four drivers and four receivers in a 24-pin SSOP package. It operates from a single 4.5V to 5.5V supply and supports data rates up to 120 kbps (230 kbps typical), making it compatible with high-speed modems and PC remote-access applications. The device uses 0.1uF external charge pump capacitors and MaxLinear's patented on-board charge pump circuitry to generate the +/-10V RS-232 voltage levels required by the TIA/EIA-232 standard. An RS-232 transceiver is a type of serial communication interface IC that bridges the logic-level UART signals of a microcontroller or processor with the higher-voltage, inverted-polarity signaling defined by the TIA/EIA-232 (formerly RS-232) standard. Within the broader semiconductor hierarchy, RS-232 transceivers sit under interface ICs, which themselves belong to the integrated circuit family alongside line drivers, bus transceivers, and level shifters. The SP208CA-L/TR is engineered for multi-channel point-to-point asynchronous serial links where reliable +/-10V signaling, electrostatic discharge (ESD) robustness, and minimal external component count are required. Key features include 4 drivers and 4 receivers in a single IC, ESD protection of more than +/-15 kV on driver output and receiver input pins for both Human Body Model and IEC 1000-4-2 air-discharge events, a 1.0uA typical shutdown current, tri-state receiver outputs, and low-power CMOS construction. The 24-pin SSOP package supports commercial temperature range (0C to +70C) and occupies minimal PCB real estate. Multiple drivers and receivers in a single package reduce both board area and total BOM cost for designs that need to implement the standard DB9 or DB25 RS-232 port complement. Technically, the SP208CA-L/TR uses a regulated dual-charge-pump voltage converter with internal switch capacitors and an architecture patented under US patent 5,306,954. The on-chip charge pump generates the +10V and -10V RS-232 rails from a single +5V input, eliminating the need for a negative supply. Driver slew rate is internally limited to reduce EMI and to meet the RS-232 transition time specification. Receivers remain operational when the device is in shutdown, which is useful for wake-up detection in DTE/DCE applications. Typical applications include point-of-sale (POS) terminals, industrial control RS-232 ports, legacy PC serial ports, embedded UART debug consoles, and any MCU/MPU system that must communicate with RS-232 peripherals. The 0.1uF external capacitors and high ESD rating make it well-suited for handheld and industrial equipment where PCB space is constrained and field ESD exposure is a concern. When designing with this part, place the four charge pump capacitors (typically four 0.1uF ceramics) as close as possible to the C1+, C1-, C2+, C2- pins to minimize ripple on the generated +/-10V rails. Observe the recommended trace geometry for the SSOP-24 thermal pad (none on this part) and provide a solid ground plane beneath the device to maximize ESD and EMI immunity. This page synthesizes distributor pricing, drop-in cross-brand alternatives from the SP208 family, application guidance, and design notes not typically aggregated on the manufacturer datasheet, giving engineers a single, citable reference for the SP208CA-L/TR.
SP232ACN-L - Dual RS-232 Transceiver | MaxLinear
The MaxLinear SP232ACN-L is a 2-channel line-driver and line-receiver transceiver for RS-232 and V.28 serial interfaces, supporting a data rate up to 120 kbps under load from a single 5 V supply in a 16-SOIC package. It provides two transmit channels and two receive channels for compact bidirectional serial links. The device uses 0.1 µF ceramic charge-pump capacitors, supports a 4.5 V to 5.5 V supply range, and is identified in distributor listings as a full RS-232 interface IC. An RS-232 transceiver is a semiconductor interface that converts between TTL/CMOS logic levels and the voltage-defined, inverting signals used on an RS-232 link. Within the broader hierarchy of interface ICs, it sits between a host controller or UART and an external serial connector. The SP232ACN-L combines driver and receiver functions in one package, reducing the component count and board area needed for two-way RS-232 communication. Key verified features include single +5 V operation, operation from 4.5 V to 5.5 V, two drivers, two receivers, and a maximum data rate of 120 kbps under load. The manufacturer describes the SP232A family as pin-to-pin compatible with popular industry-standard pinouts and suitable for commercial applications. The charge-pump function supports operation with small ceramic capacitors rather than requiring large electrolytic capacitors. The SP232A family uses a BiCMOS design and implements enhanced RS-232 line-driver and receiver functions. In a typical UART connection, the host TX signal enters a driver and becomes an RS-232-level signal, while an incoming RS-232 signal passes through a receiver and becomes a CMOS-compatible signal for the host. The interface is appropriate when the link requires the established RS-232 voltage levels rather than short-distance TTL signaling. Typical uses include industrial serial consoles, instrumentation, data acquisition, point-of-sale equipment, embedded debug ports, and legacy computer peripherals. In these systems, the transceiver bridges a low-voltage UART or processor port to an external RS-232 connector. Cable length, grounding, shielding, and connector-level ESD protection remain important system considerations; the IC does not eliminate the need for a suitable connector and protection network. A practical design tip is to place the charge-pump capacitors close to their marked pins and keep the RS-232 traces short and isolated from sensitive analog or high-speed digital paths. The selected 16-SOIC footprint is suitable for conventional surface-mount assembly, but the exact pin names and package details should be confirmed against the manufacturer datasheet before layout. This product record combines verified distributor specifications, manufacturer-family information, cross-reference results, practical interface design notes, and availability-focused commercial guidance for engineers evaluating the SP232ACN-L.
SP232ACN-L/TR - 2/2 RS-232 120kbps IC | MaxLinear
MaxLinear SP232ACN-L/TR is a 2-driver, 2-receiver RS-232 line transceiver designed for 4.5V to 5.5V single-supply operation, with a verified 120kbps data rate and a 16-SOIC package. The device uses CMOS/BiCMOS technology and supports the EIA/TIA-232 and V.28 serial communication protocols. An RS-232 transceiver is an interface IC that converts logic-level signals into balanced, single-ended RS-232 line signals and converts received line signals back into logic levels. In the broader electronics hierarchy, it belongs to the communications-interface class, then to the RS-232 interface family and ultimately to interface semiconductors. This makes it suitable for connecting TTL or CMOS logic systems to legacy serial ports, industrial equipment, test systems, and embedded control products. The SP232A family emphasizes compatibility with standard RS-232 pinouts, small ceramic charge-pump capacitors, and commercial-temperature operation. The verified manufacturer description identifies two drivers and two receivers, operation from a single +5V supply, and a data rate of 120kbps under load. Its 16-SOIC package supports conventional surface-mount PCB assembly, while the /TR ordering code identifies the tape-and-reel shipping format. The interface uses charge-pump circuitry to generate the positive and negative RS-232 voltage levels needed by the drivers from a single supply. Because RS-232 is a single-ended, bipolar signaling standard, the transceiver is useful where longer cable runs or greater noise tolerance are needed compared with ordinary TTL-level serial links. The device must still be paired with correct protection, grounding, and signal-integrity practices in the complete system. Typical applications include RS-232 ports in embedded systems, programmable-logic or microcontroller debug communications, laboratory instrumentation, industrial controllers, barcode and test equipment, and legacy peripheral connections. The 120kbps rate is suitable for moderate-speed serial links, while the 2/2 configuration allows two bidirectional channels in one package. When placing the device, keep the RS-232 connector-side traces short where practical, provide the charge-pump capacitors required by the manufacturer, and observe the exact pinout and supply decoupling arrangement. Verify line protection and ESD requirements at the connector because the interface IC does not eliminate the need for an external protection strategy. This product page consolidates the verified distributor and manufacturer data, identifies same-footprint alternatives, and separates known electrical facts from parameters that require application-specific confirmation. It is intended to support component selection and early board planning rather than replace the complete manufacturer datasheet.

The MaxLinear, Inc. SP232ACP-L is a two-driver, two-receiver RS-232 line-driver and receiver transceiver operating from a single 4.5 V to 5.5 V supply. It supports data rates up to 120 kbps under load, provides 2 kV ESD protection, and is packaged in a 16-pin PDIP. The device also uses compact 0.1 µF charge-pump capacitors, reducing the external component count required for RS-232 voltage translation. An RS-232 transceiver is an interface IC that converts digital logic-level signals into RS-232 line levels and converts received RS-232 signals back into logic-compatible levels. The SP232ACP-L belongs to the RS-232 transceiver category, which sits within interface ICs and broader semiconductor communication devices. It is intended for point-to-point serial links where the connected equipment uses the EIA/TIA-232 and V.28 protocols. The SP232ACP-L integrates two drivers and two receivers, allowing one interface IC to support a full bidirectional serial channel. Its 120 kbps under-load capability is suitable for data acquisition, industrial control, instrumentation, and legacy peripheral connections. The single 5 V supply simplifies power design, while 0.1 µF charge-pump capacitors provide a practical option for compact circuit boards. Because the device is pin-to-pin compatible with popular industry-standard RS-232 layouts, it can support straightforward replacement of compatible interface hardware. The single 5 V supply simplifies power design, while 0.1 µF charge-pump capacitors provide a practical option for compact circuit boards. The SP232ACP-L is suitable for industrial equipment, test and measurement systems, point-of-sale terminals, embedded serial controllers, and instrumentation with RS-232 ports. Its 0 °C to 70 °C commercial temperature range suits indoor equipment where an extended-temperature component is unnecessary. Systems exposed to temperature extremes or severe conducted noise should verify environmental requirements separately. The primary design consideration is correct charge-pump capacitor placement. The specified 0.1 µF capacitors should be connected exactly as shown in the manufacturer datasheet, with short traces and a solid ground reference. Designers should also account for RS-232 cable-length, grounding, and signal-integrity requirements rather than treating the transceiver as a general-purpose logic buffer. This product record consolidates verified supply, protocol, package, temperature, ESD, and data-rate information with practical selection guidance. It also distinguishes the SP232ACP-L from a cross-brand RS-232 alternative while clearly identifying which additional comparison data remain unavailable from the supplied sources.
SP232ACT-L - 120kbps RS-232 Transceiver | MaxLinear
The MaxLinear SP232ACT-L is a 120 kbps RS-232 line transceiver with two drivers and two receivers, a single +5 V supply, and a 16-pin SOIC package. Its BiCMOS implementation supports low-power operation, ceramic charge-pump capacitors, and compatibility with established RS-232 interface layouts. An RS-232 transceiver is an interface IC that converts between digital logic levels and the bipolar voltage levels used by RS-232 serial links. Within the hierarchy of interface semiconductors, it sits between general-purpose logic ICs and communications transceivers. The SP232ACT-L integrates charge-pump circuitry, transmit drivers, and receive comparators to support point-to-point serial communication over cables or board-level links. Key features include operation from a 4.5 V to 5.5 V supply, a guaranteed transmission rate of 120 kbps, and compatibility with RS-232F and ITU V.28 requirements. The device operates with 0.1 F ceramic capacitors, supports a 10 V/µs slew rate, and provides enhanced ESD protection up to ±15 kV under the cited IEC 61000-4-2 and HBM test conditions. The BiCMOS architecture combines low-power CMOS circuitry with bipolar output stages capable of driving RS-232 loads. Its pin-compatible relationship with established industry-standard layouts simplifies replacement and PCB migration. Because the interface uses charge-pump-generated bipolar voltages for transmission, board design must account for capacitor placement, return-current flow, and ESD protection around the external connector. Typical applications include industrial serial consoles, data acquisition systems, test and measurement equipment, embedded control interfaces, and legacy RS-232 peripheral connections. The 120 kbps rate is suitable for command and control traffic rather than high-bandwidth data transfer. For reliable implementation, place the charge-pump capacitors close to their associated pins and provide a clean return path between the interface ground and the external connector. Confirm line voltage, cable length, and grounding before assuming the full 120 kbps specification applies to every cable and load arrangement. This product page combines verified manufacturer and distributor information, drop-in cross-reference data, comparison parameters, and application guidance to support faster component selection, sourcing, and circuit implementation.
SP232ACT-L/TR - 120kbps RS-232 Transceiver | MaxLinear
The MaxLinear SP232ACT-L/TR is a single-supply RS-232 line-driver and receiver IC with two drivers and two receivers, a maximum data rate of 120 kbps, and a 16-SOIC package. It operates from a single +5 V supply and supports 0–70 °C commercial-temperature applications. The device also provides a 10 V/µs slew rate and an on-board regulated charge pump that produces approximately ±6.5 V for compliant RS-232 signal levels. An RS-232 transceiver is an interface IC that bridges TTL-compatible digital logic and balanced, single-ended RS-232 communications. The SP232A belongs to the RS-232 transceiver hierarchy: interface IC, communications transceiver, line driver and receiver, and power-management-assisted interface. Its integrated charge-pump circuit raises the +5 V supply to the positive and negative voltages required for RS-232 drivers, while the receiver section converts incoming RS-232 levels back into TTL-compatible signals. Key features include two transmit channels, two receive channels, 120 kbps operation under load, 10 V/µs driver slew rate, and operation with small 0.1 µF ceramic charge-pump capacitors. The SP232A is designed to be pin-to-pin compatible with popular industry-standard RS-232 pinouts, simplifying replacement of compatible transceivers. Its 16-SOIC format also supports compact point-to-point and multi-port serial-interface designs. Technically, the charge pump generates the bipolar voltage required by the drivers, and the transmitter circuitry converts TTL input levels into RS-232 output levels. The receiver threshold circuitry detects the negative-going RS-232 signal used to indicate logic one. Because this is a single-supply design, system designers should account for the remaining voltage-drop budget across the interface and cable rather than assuming a modern low-voltage RS-232 architecture. Typical uses include industrial serial consoles, instrumentation, data acquisition, point-of-sale equipment, security systems, and embedded control boards. The device is especially useful where a legacy RS-232 port must coexist with +5 V TTL logic and where a 120 kbps data rate is sufficient. For new designs requiring higher speed, lower supply voltage, or automatic shutdown, the complete family specification should be compared before fixing the PCB footprint. A key implementation consideration is capacitor selection and placement. The manufacturer specifies 0.1 µF ceramic charge-pump capacitors, so use the approved dielectric and voltage rating and place each capacitor close to its associated device pins. Keep the RS-232 connector and transceiver interface path away from sensitive clocks, ADC inputs, and switching-node traces to reduce noise coupling. This page consolidates verified distributor facts, the manufacturer SP232A datasheet, cross-reference evidence, practical design guidance, and same-package replacement information that can be evaluated quickly during component selection and PCB bring-up.
SP232AEN-L - 120kbps RS-232 Transceiver | MaxLinear
The MaxLinear SP232AEN-L is a single-supply RS-232 line-driver and receiver transceiver with two transmit and two receive channels, 120 kbps data rate, and a 16-pin SOIC package. The verified manufacturer data also identifies a regulated on-board charge pump, approximately +6.5 V and -6.5 V RS-232 output levels, 0.1 uF ceramic charge-pump capacitors, and compatibility with popular industry-standard pinouts. Its operating temperature range is -40 C to 85 C, making it suited to industrial and commercial equipment requiring a compact multi-channel serial interface. An RS-232 transceiver is an interface IC that translates between CMOS/TTL logic and balanced, bipolar RS-232 signal levels. It belongs to the line-driver and receiver hierarchy, within interface ICs and serial-interface devices. The transmitter converts low-voltage digital signals into RS-232 levels, while the receiver converts incoming RS-232 levels back into logic-compatible signals. This bidirectional level translation allows equipment such as test instruments, industrial controllers, and computer peripherals to communicate over longer cable runs than ordinary CMOS signals support. The SP232AEN-L provides two transmit and two receive functions in one package, reducing board area compared with discrete line-driver and receiver solutions. Its 120 kbps maximum data rate is suitable for moderate-speed serial links, while the single 5 V supply simplifies system power design. The datasheet also specifies a 10 V/us slew rate, which helps control transition behavior on the RS-232 output. The -L ordering suffix and 16-pin SOIC package are identified in distributor results, while exact marking, tape-and-reel, and lead-free details should be confirmed against the manufacturer documentation. The SP232A family is described by MaxLinear as pin-to-pin compatible with popular industry-standard pinouts and as a replacement for earlier SP231, SP232, and SP233 versions. The verified comparison data references SP232ECN-L and SP232EET, but their manufacturer, package details, and full electrical parameters are not fully supplied here. The datasheet snippet specifically reports enhanced ESD capability of +/-15 kV using the IEC 61000-4-2 model and +/-15 kV using the Human Body Model, but the applicable test conditions and exact device suffix should be checked in the datasheet. Typical applications include RS-232 links in industrial controllers, test and measurement equipment, serial adapters, instrumentation, and embedded systems that require more than one serial channel. The 16-pin SOIC package is easy to route on conventional through-hole-compatible PCB land patterns, provided the exact pin assignment and exposed-pad status are confirmed. Designers should provide the specified 0.1 uF charge-pump capacitors close to the associated pins and maintain adequate signal-return and cable shielding practices. For new designs, verify supply tolerances, receiver thresholds, driver output levels, ESD requirements, and channel direction against the complete manufacturer datasheet before release. Do not infer that every similarly named SP232 variant is interchangeable without checking the exact pinout, package, temperature rating, and electrical limits.
SP232AEN-L/TR - 120kbps Dual RS-232 Transceiver | MaxLinear
The MaxLinear SP232AEN-L/TR is a dual RS-232 line-driver and receiver interface IC supporting data rates up to 120 kbps under load, packaged in a 16-lead SOIC. The device operates from a single 4.5 V to 5.5 V supply and is specified across -40°C to +85°C. It uses a BiCMOS implementation and 0.1 µF ceramic charge-pump capacitors, allowing compact RS-232 designs without an external regulated charge-pump supply. An RS-232 transceiver is a signal-interface semiconductor that converts logic-level UART signals into RS-232 voltage levels and converts received RS-232 levels back into logic-compatible signals. The SP232A belongs to the broader hierarchy of interface ICs, serial-interface transceivers, communication transceivers, and semiconductors. It is used where a host, controller, terminal, or embedded system must connect to a longer-distance, noise-tolerant RS-232 port. Key features include two driver and two receiver channels, compatibility with RS-232 and V.28 protocols, a 120 kbps data rate under load, and pin-to-pin compatibility with popular industry-standard pinouts. The manufacturer datasheet identifies small 0.1 µF ceramic charge-pump capacitors as a key implementation detail. The single 5 V supply and industrial temperature range support equipment operating across industrial and commercial environments. The BiCMOS architecture combines bipolar and CMOS characteristics in the driver and receiver circuitry. This is relevant when designing a UART link because the interface must translate between low-voltage digital logic and the larger voltage swings defined by RS-232 while maintaining receiver discrimination under cable noise. The SP232A is intended for point-to-point serial communication rather than multidrop RS-485 networks. Typical applications include industrial serial consoles, programmable-logic-controller service ports, test instrumentation, point-of-sale equipment, barcode-scanner interfaces, and embedded UART-to-RS-232 adapters. In each case, the transceiver is placed between the UART controller and the external DB9 or other RS-232 connector, with the charge-pump capacitors and bypass capacitor placed close to the device. For a new PCB, follow the manufacturer datasheet for the charge-pump capacitor connection, ground-return arrangement, and decoupling placement. Keep the connector-side interface trace short, provide a solid ground reference, and confirm the downstream UART baud rate and cable length. The SP232AEN-L/TR is not an RS-485 transceiver, so it should not be used where multi-drop bus arbitration and differential signaling are required. This page combines verified distributor listings, the MaxLinear SP232A datasheet, package information, application context, and a constrained drop-in replacement review. The listed alternatives are included only where the available cross-reference evidence identifies compatible package-level substitutions; engineers should still verify speed, ESD, supply, and lifecycle requirements before production use.
SP232AEP-L - 16-Pin RS-232 Transceiver | MaxLinear
The MaxLinear, Inc. SP232AEP-L is a 5 V single-supply RS-232 line-driver and receiver transceiver packaged in a 16-pin PDIP. It provides two driver and two receiver channels in one integrated circuit, making it suitable for bidirectional and multi-channel serial-interface designs. The device is described as compatible with RS-232 and V.28 protocols and pin-to-pin compatible with popular industry-standard pinouts. An RS-232 transceiver is an interface IC that converts logic-level UART signals into RS-232 levels and converts received RS-232 signals back into CMOS-compatible logic. Within the broader hierarchy of semiconductor interfaces, this device is a transceiver, an RS-232 interface IC, a line-driver/receiver pair, and a power-management-compatible peripheral for legacy serial ports. It is commonly associated with industrial equipment, computer peripherals, instrumentation, and embedded control systems that retain a DB9 or equivalent RS-232 connection. The SP232A family provides a 120 kbit/s data rate under load, as stated in the retrieved SP232A documentation. MaxLinear's product-page description also presents an 80 kbit/s under-load rate for the family, so the two retrieved sources differ and both values are retained here rather than silently choosing one. The difference may reflect device-family wording, test conditions, or source revision differences. The verified product materials also identify small 0.1 µF ceramic charge-pump capacitors as a characteristic of the SP232A implementation. The device uses MaxLinear's BiCMOS design, combining bipolar and CMOS process characteristics to support the line-driver and receiver functions required by RS-232. Its single-supply operation simplifies system power design compared with traditional ±12 V RS-232 interfaces. Nevertheless, the charge-pump network still creates the bipolar voltage levels required to drive an RS-232 receiver threshold, and correct capacitor selection and layout remain essential. Typical uses include connecting a UART-equipped controller to an industrial serial peripheral, upgrading a legacy PC serial port, communicating with test equipment, and building multi-channel RS-232 links. The 16-pin PDIP format is appropriate for through-hole industrial boards and prototypes, although it occupies more board area than surface-mount RS-232 transceivers. Designers should place the charge-pump capacitors close to their associated pins, route RS-232 driver outputs away from sensitive receiver inputs, and provide suitable protection for exposed external cables. The -40 °C to +85 °C temperature range is specifically listed in the Mouser product result, making the device suitable for extended commercial and industrial environments when the complete system qualification supports that range. This page consolidates the verified distributor and manufacturer information, identifies the documented protocol, package, speed, temperature, and charge-pump characteristics, and separates confirmed drop-in candidates from replacement options that require further engineering verification.

Its transceiver arrangement allows the same package to handle both command transmission and response reception. Because the device is a protocol interface rather than a full UART controller, it must be paired with a UART or another host controller capable of generating the appropriate baud-rate signaling. Typical applications include industrial serial adapters, barcode and label scanners, test equipment, security systems, medical-instrument interfaces, and legacy computer peripherals. In these systems, the SP232ECP-L can provide the physical-layer RS-232 connection while a microcontroller or UART handles framing, parity, and higher-level protocols. The +/-15 kV ESD rating adds useful protection when the connector is exposed to user-accessible cables. Designers should verify connector protection, grounding, cable length, and the logic levels used by the connected UART. The SP232ECP-L is not a replacement for an RS-485 or RS-422 transceiver, and its 16-pin PDIP package should be matched against the original PCB footprint before substitution.

Receivers operate from the main 3.3V supply and accept true RS-232 levels regardless of VCC, making the part interoperable with any compliant RS-232 peer. Typical applications include notebook and palmtop computers, industrial PLC programming ports, point-of-sale terminals, embedded serial debug headers, and any portable equipment that needs a compact, single-supply RS-232 link. Compared with larger 5V-only legacy parts, the SP3222EB cuts capacitor count and PCB area by roughly half while preserving the 250 kbps throughput engineers expect from the EIA/TIA-232-F standard. When designing with this device, place the four 0.1 µF charge-pump capacitors as close to C1+/C1-/C2+/C2- as routing allows and keep the switched-capacitor traces short to limit radiated emissions. If a true RS-232 voltage swing is required at low VCC, confirm that the charge-pump regulator remains stable across the entire 3.0V to 5.5V input range. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving buyers and design engineers a single reference for sourcing and applying the SP3222EBEY-L/TR.
