AM26LV32IDR 개요
A differential line receiver is an interface circuit that converts a balanced differential signal into a single-ended logic signal while rejecting common-mode noise. In the interface hierarchy, it belongs to the receiver class of RS-422 interface ICs, which sit between a physical communication bus and digital logic. The AM26LV32IDR is optimized for low-voltage, high-speed point-to-point or multidrop communication where four channels must be received in one package.
Key features include four differential receivers, a common enable control for all outputs, and 3-state output capability for bus isolation. The BiCMOS architecture combines low power dissipation with high switching performance. The device is specified for a 3.3 V supply, making it suitable for systems whose digital core operates from the same voltage rail. Its 32 MHz maximum switching rate supports substantially faster signaling than conventional low-speed RS-422 receivers.
The AM26LV32 family is intended for balanced differential buses and point-to-point data links. Its reduced common-mode voltage range is a consequence of the low supply voltage, so the complete bus voltage and grounding plan must remain within the device's specified operating limits. The common enable function allows the receiver outputs to enter a high-impedance state when the host needs to isolate the interface.
Typical uses include industrial automation equipment, test and measurement instruments, computer peripherals, data acquisition systems, and multi-channel communication links. Because each channel is independent, the IC can also serve monitoring, redundant sensing, or distributed input systems where four differential signals share a common supply.
When laying out a board, keep the differential traces short, matched, and continuous over a common ground reference. Place receiver bypass capacitors close to the supply pins and follow the manufacturer's recommended termination and protection practices. Verify that the driver, cable, connector, and receiver common-mode limits remain compatible across temperature and supply tolerance.

일반적인 애플리케이션
AM26LV32IDR 적합 용도: 6 애플리케이션s: Industrial Automation Communication, Test and Measurement Equipment, Data Acquisition Systems, Computer and Peripheral Interfaces, Multi-Channel Sensor Monitoring, Redundant and Monitoring Communication.
Industrial Automation Communication
The AM26LV32IDR fits 3.3 V industrial automation links that need four balanced differential inputs in one package. Its quadruple receiver architecture reduces the number of interface components and helps organize multi-axis, sensor, or remote I/O data paths. The 32 MHz switching-rate capability is useful when the system must preserve signal integrity across short printed-circuit or short cable interconnects. Place the device near the connector, maintain a continuous ground reference, and verify that the bus common-mode voltage remains within the receiver's limits.
추천
Test and Measurement Equipment
AM26LV32IDR can receive four differential channels in instrumentation systems where measurement or control signals must be converted from a balanced bus to digital logic. The 3.3 V supply is convenient for modern mixed-signal and digital control platforms, while the high-speed receiver helps preserve timing margin in test systems. Designers should route each differential pair as a controlled-impedance pair, provide local supply bypassing, and validate the source termination and cable length for the intended signaling rate.
추천
Data Acquisition Systems
The four independent AM26LV32IDR receiver channels suit compact data-acquisition front ends that must accept multiple differential signals while sharing a 3.3 V system rail. The common enable allows a controller to disable or isolate all channels together, which can help simplify reset and bus-sharing behavior. For accurate acquisition, use matched routing, minimize stubs, keep return-current paths continuous, and confirm that the source amplitude and common-mode level meet the receiver requirements.
추천
Computer and Peripheral Interfaces
AM26LV32IDR can support legacy-style balanced peripheral links when a 3.3 V system needs four receive channels and a high-speed differential receiver. Its 3-state outputs are useful when the host must place the interface in an inactive state or share a bus without driving the output node. Compatibility still depends on the original interface's voltage levels, termination scheme, connector pinout, and signal-rate requirements, so legacy peripheral designs should be reviewed against the original system specification.
추천
Multi-Channel Sensor Monitoring
The AM26LV32IDR is appropriate when several remote or distributed sensor outputs use balanced differential signaling and need to enter a common digital receiver. Four channels in one 16-pin SOIC can simplify wiring and provide consistent electrical loading. The receiver's 3.3 V operation aligns with compact sensor and controller systems, but sensor output common-mode voltage must remain within the device's specified range. Shielding, grounding, and cable routing should be selected for the installation environment.
추천
Redundant and Monitoring Communication
The independent receiver channels of AM26LV32IDR can be used in monitoring systems where several bus nodes or redundant signals must be observed by one controller. The common enable provides a straightforward way to place the four outputs in a defined high-impedance state during reset or maintenance. A redundant architecture should still include separate power and fault analysis for each signal path, and engineers should verify that the receiver's common-mode range and timing behavior meet the reliability requirements of the monitored system.

주요 차별점
- Four independent differential receivers in one 16-pin SOIC (vs DS90LV032ATMX/NOPB)
- Verified 3.3 V low-voltage operation (vs AM26LV32ID)
- High-speed 32 MHz switching-rate positioning (vs AM26LV32EIDR)
설계 노트
Place the receiver close to the connector or cable-entry point so the differential pair reaches the IC without unnecessary stubs. Route each pair over a continuous reference plane with closely matched spacing, and avoid sharing a narrow return-current path with unrelated high-current signals. This is particularly important for a high-speed receiver whose benefit depends on preserving differential signal integrity rather than merely recovering a logic level.
Provide local supply bypassing at the AM26LV32IDR pins according to the manufacturer layout and decoupling recommendations. The verified device operates from a 3.0 V to 3.6 V supply, so power routing should be sized for the required channel count and the source's current behavior. Keep the 3.3 V rail away from switching-node noise and maintain a low-impedance ground return between the receiver and its bypass components.
Do not assume that any 16-pin 0/4 receiver is automatically interchangeable. The retrieved cross-reference data identifies DS90LV032ATMX/NOPB and DS26LV32ATM as same-package candidates, but it does not provide complete pin, timing, common-mode, or supply tables. Before substitution, verify every pin, enable polarity, input threshold, output timing, temperature range, and supply range against the original design requirements.
Termination, cable length, driver edge rate, and receiver common-mode range must be considered together. The AM26LV32IDR is optimized for balanced buses at switching rates up to 32 MHz, but the maximum usable link rate can be lower when cable loss, skew, reflections, or grounding are unfavorable. Validate the complete driver-to-receiver path with the intended cable and connector rather than relying on the receiver rating alone.
