SN75182N - Dual Differential Line Receiver | Texas Instruments
MPN: SN75182N ✓ فعالSN75182N جائزہ
A differential line receiver is an interface IC that converts the voltage difference between two input terminals into a single-ended logic signal. Its differential input architecture rejects noise shared equally by both signal conductors, while the receiver threshold determines when the differential voltage produces a valid logic state. The SN75182 belongs to the broader line-receiver, interface-IC, and semiconductor hierarchy and is intended for systems where reliable signal recovery is more important than directly processing bipolar signals with digital logic.
The SN75182N includes separate channels with individual channel strobes, allowing receiver activity to be controlled when interfacing with shared buses, test equipment, or multi-source systems. Each channel's frequency response can be adjusted with one external capacitor, providing a practical means of balancing signal bandwidth against noise immunity. The device also supports an optional internal line-termination resistor, helping simplify implementations where controlled input impedance and noise reduction are useful.
According to the Texas Instruments SN75182 datasheet, TTL-compatible output signals indicate the polarity of the differential input voltage. The 4.5 V to 5.5 V single-supply range places the part in conventional 5 V digital-interface environments. Its two-channel architecture reduces component count when two differential links must be received simultaneously, while the common-mode range provides tolerance for ground offsets and coupled noise encountered in longer industrial or communication links.
Typical uses include balanced data acquisition, industrial control links, test and measurement systems, peripheral interfaces, and communications equipment operating with small differential signals over larger common-mode voltages. The receiver is especially relevant where a transmitted differential signal must be recovered reliably before being passed to TTL-compatible logic.
PCB implementation should preserve the differential signal path, minimize unequal routing between each input pair, and place the frequency-control capacitor close to its designated device pin. Differential impedance and termination arrangements should be evaluated together because the optional internal termination may change the effective input loading. The manufacturer's pin-description and typical-application information should guide final routing and capacitor selection.
This product page combines the SN75182N's verified electrical characteristics with practical interface guidance, package information, sourcing instructions, and a technically qualified replacement assessment. It is intended to help engineers determine whether the receiver's differential sensing, channel-strobe functions, and bandwidth-control features fit a specific signal-chain requirement before beginning layout.

Industrial Balanced Data Links
The SN75182N is appropriate for industrial balanced links in which a small differential signal must be recovered from a larger common-mode environment. According to the Texas Instruments SN75182 datasheet, the receiver accepts a ±15 V common-mode input range and a ±15 V differential input range while producing TTL-compatible outputs. Two channels allow two balanced links to share one interface device, reducing component count compared with separate single-channel receivers. Each channel also has an individual strobe and a frequency-control capacitor, so the system can disable an inactive receiver or tailor bandwidth to the line. The design must preserve symmetrical routing between each input pair and maintain rated input voltages during normal operation and fault conditions.
Test and Measurement Systems
The SN75182N can serve as the receiving stage in test and measurement equipment that accepts bipolar or balanced input signals but requires a digital representation for processing. According to the Texas Instruments SN75182 datasheet, the device senses differential signal polarity despite large common-mode noise and supplies TTL-compatible outputs. The adjustable frequency response, controlled by one external capacitor per channel, allows each receiver path to trade useful bandwidth for additional noise immunity. Two independently strobed channels are useful when instruments must qualify or isolate multiple inputs. Calibration and signal-integrity work should account for input impedance, optional termination state, propagation behavior, and the effect of external capacitance on the complete measurement path.
Peripheral Communication Interfaces
The SN75182N is suitable for peripheral communication equipment that uses a small differential signal over a pair of conductors with noise or ground-offset tolerance requirements. According to the Texas Instruments SN75182 datasheet, its differential sensing rejects common-mode noise and converts the input polarity into a TTL-compatible signal. The dual-channel implementation can support two related communication paths, while individual strobes provide local activity control. The 4.5 V to 5.5 V supply range fits conventional 5 V logic systems. Engineers should use the manufacturer's typical interface arrangement to confirm line termination and capacitor values, then verify that the complete transmitter, cable, and receiver loading supports the intended data rate without excessive reflections or loss of bandwidth.
Balanced Sensor Signal Conditioning
The SN75182N can receive weak differential outputs from sensors or sensor-interface circuits when the signal is exposed to common-mode voltage. According to the Texas Instruments SN75182 datasheet, its ±15 V common-mode input range provides substantial margin for systems in which both sensor lines move together relative to the receiver ground. The resulting TTL-compatible output can be connected to digital acquisition or control logic. Channel-specific frequency capacitors permit each signal path to be tuned according to its bandwidth and noise requirements. The receiver is not itself an analog amplifier or sensor front end, so system designers must still establish sensor excitation, scaling, grounding, and bandwidth before applying the receiver. Differential impedance and grounding symmetry remain critical to preserving the expected noise rejection.
Digital Control Equipment
The SN75182N is useful in digital control equipment that receives command or status information over differential lines while operating from a 5 V logic rail. According to the Texas Instruments SN75182 datasheet, two differential receiver channels provide TTL-compatible outputs, and the ±15 V common-mode range can accommodate ground differences between communicating assemblies. Individual channel strobes permit the controller to ignore or qualify one input path while another is active. The optional internal line termination helps create a defined load when enabled, although source and cable impedance must be included in the termination calculation. Layout should keep each differential pair adjacent, minimize stub branches, and place frequency-control capacitors near the receiver to preserve noise performance and predictable signal timing.
Legacy Differential Bus Interfaces
The SN75182N can support legacy or proprietary differential bus interfaces that combine bipolar signaling with TTL-compatible receiver electronics. According to the Texas Instruments SN75182 datasheet, it is designed to sense small differential signals in the presence of large common-mode noise and reports the input polarity through TTL-compatible outputs. The two-channel arrangement can receive two related bus lines, and the selectable termination and adjustable frequency response offer flexibility for different cable and source characteristics. Because legacy buses can contain long interconnects and substantial ground offsets, verify connector and cable behavior as part of the receiver design. Ground and surge requirements must also be evaluated independently; the receiver's input voltage ratings do not replace appropriate external protection.

ڈیزائن نوٹس
Route each differential input pair as a tightly coupled pair with consistent geometry and minimal impedance discontinuity. Keep the two channels physically separated when crosstalk could couple large common-mode energy into a low-level differential signal. Place the frequency-control capacitor close to the corresponding device pin and use the manufacturer pin-description table to avoid routing the capacitor through unrelated high-impedance or switching nodes.
Evaluate source impedance, line impedance, receiver termination, and external capacitance together. The optional internal termination resistor can establish a controlled input load, but its enabled or disabled state must match the ordered variant and the complete link budget. Confirm that the selected frequency-control capacitor preserves the required data bandwidth while providing the intended differential-noise attenuation.
Do not assume that the ±15 V input ranges permit arbitrary bipolar input conditions. Common-mode voltage, differential voltage, and the combined input condition must all remain within the device limits, including during startup and fault states. Because the receiver does not replace external surge or ESD protection, determine whether the interface requires series damping, clamps, or other network-specific protection.
