Product details
Overview
DS26C32AMW/883 from Texas Instruments is a quad differential line receiver designed for RS-422 and RS-423 balanced data transmission systems, featuring ±0.2 V input sensitivity over ±7 V common-mode range, TRI-STATE outputs with 6 mA drive capability, and fail-safe input circuitry. It operates across −55°C to +125°C and supports high-reliability aerospace and defense applications requiring MIL-STD-883 Class B screening.
For engineers reviewing the DS26C32AMW/883 datasheet, DS26C32AMW/883 pinout, DS26C32AMW/883 application, or DS26C32AMW/883 equivalent, this device delivers deterministic 35 ns propagation delay, low 25 mA quiescent current, and robust ±14 V absolute maximum differential input voltage - critical for noise-immune industrial serial links and avionics backplanes.
Technical Context
The DS26C32AMW/883 implements four independent CMOS-based differential receivers with shared enable control, each incorporating internal pull-up/pull-down resistors to prevent floating outputs during channel disable. Its input stage tolerates −7 V to +7 V common-mode voltage while maintaining 200 mV differential threshold detection.
TRI-STATE output logic enables bus-sharing via external enable signals, with 29 ns enable/disable timing and rail-to-rail output swing (VOH ≥ 3.8 V at IO = −6 mA, VOL ≤ 0.3 V at IO = 6 mA). The device remains electrically inert when VCC = 0 V, eliminating bus loading during power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V logic rails and stable operation under supply variation. |
| Differential Input Sensitivity | ±200 mV - guarantees reliable logic-level decisioning even under degraded signal integrity in noisy environments. |
| Common-Mode Range | ±7 V - supports long-cable RS-422 links with ground potential differences up to 14 V between nodes. |
| Propagation Delay | 35 ns max - enables reliable operation at data rates up to ~10 Mbps in point-to-point or multidrop configurations. |
| Output Drive Strength | 6 mA sink/source - sufficient to directly drive multiple TTL loads or terminate stubs without external buffers. |
| Quiescent Current | 25 mA max - minimizes system power budget in always-on communication subsystems. |
| Operating Temperature | −55°C to +125°C - qualified per MIL-STD-883 for extended life in harsh military, space, and downhole applications. |
Pinout & Package
Ceramic Flatpack (CFP) package, 16-pin, hermetically sealed, with 0.050-inch lead pitch and 2.33 mm max height (Package Code NAD0016A). Designed for high-reliability mounting on ceramic substrates or metal-core PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | Inverting Input (A−, B−, C−, D−) | Differential negative inputs for channels A–D; referenced to corresponding non-inverting inputs for polarity-sensitive decoding. |
| 2, 4, 6, 8 | Non-Inverting Input (A+, B+, C+, D+) | Differential positive inputs for channels A–D; paired with pins 1/3/5/7 to detect valid RS-422 signal transitions. |
| 9, 11, 13, 15 | Output (YA, YB, YC, YD) | TRI-STATE CMOS outputs; driven high/low when enabled, high-impedance when /EN asserted. |
| 10 | /ENABLE | Active-low global enable controlling all four outputs; asserts high-impedance state when logic high. |
| 16 | VCC | Positive supply terminal; must be decoupled locally to suppress switching noise coupling into analog input paths. |
| 12 | GND | Signal reference plane; requires low-inductance connection to minimize ground bounce during output transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-Safe Input Circuitry | Guarantees logic-high output when inputs are open, shorted, or unterminated - prevents undefined bus states in fault conditions. |
| Zero-Voltage Input Loading | Inputs present no load to transmission lines when VCC = 0 V - enables hot-swap and power sequencing without signal corruption. |
| CMOS Power Efficiency | 25 mA ICC at 5.5 V supply - reduces thermal load in dense avionics modules where convection cooling is limited. |
| RS-422 Compliance | Fully meets EIA RS-422 electrical requirements including differential threshold, common-mode range, and output drive - eliminates need for external level-shifting. |
| TRI-STATE Bus Interface | Single /ENABLE pin controls all four outputs simultaneously - simplifies control logic and reduces FPGA I/O count in multi-channel designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad differential receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS26LS32AMW/883 | Bipolar process; higher 45 mA ICC; 40 ns propagation delay; same pinout and function. | Higher power consumption limits use in thermally constrained modules; slightly slower timing affects >8 Mbps designs. | Select when legacy bipolar compatibility or marginally better noise immunity at high frequencies is required. |
| AM26LS32AW/883 | Identical pinout and DC specs; 45 ns max tPLH/tPHL; 50 mA ICC; not qualified to MIL-STD-883 Class B. | Lacks full radiation-hardened screening and extended temperature validation; unsuitable for flight-critical systems. | Choose only for cost-sensitive ground-test equipment where full MIL-QPL qualification is unnecessary. |
Compared with DS26C32AMW/883, the DS26LS32AMW/883 trades lower power for marginally higher noise immunity but increases thermal load, while the AM26LS32AW/883 omits MIL-STD-883 screening - making DS26C32AMW/883 the sole option meeting full Class B requirements for flight hardware.

FAQ
What is the absolute maximum differential input voltage rating for DS26C32AMW/883?
The DS26C32AMW/883 has an absolute maximum differential input voltage rating of ±14 V. This specification allows the device to withstand transient overvoltages and ground potential differences commonly encountered in long-distance RS-422 installations without damage or latch-up, provided common-mode voltage remains within ±14 V limits.
Does DS26C32AMW/883 require external pull-up or pull-down resistors on its inputs?
No, DS26C32AMW/883 does not require external pull-up or pull-down resistors on its inputs. The device integrates internal fail-safe biasing that ensures defined logic-high outputs when inputs are open, shorted, or unterminated - eliminating external components and reducing board area in space-constrained designs.
Can DS26C32AMW/883 operate with a 3.3 V supply?
No, DS26C32AMW/883 is specified only for 4.5 V to 5.5 V operation. Its internal CMOS structure and output drive characteristics are optimized for 5 V logic families; operation below 4.5 V violates recommended conditions and may result in undefined output states or increased propagation delay beyond datasheet limits.
What is the meaning of "/883" in DS26C32AMW/883?
The "/883" suffix in DS26C32AMW/883 indicates compliance with MIL-STD-883, Method 5005 Group A testing, including static/dynamic functional tests across −55°C to +125°C, settling time verification, and switching parameter validation. This designation confirms full military-grade screening and qualification for high-reliability applications.
Is DS26C32AMW/883 pin-compatible with DS26C32AME/883?
Yes, DS26C32AMW/883 is pin-compatible with DS26C32AME/883. Both share identical 16-pin CFP (NAD0016A) and 20-pin LCCC (NAJ0020A) footprints respectively, and maintain identical pin functions, enabling direct substitution in existing layouts when upgrading from CDIP or selecting alternate package forms for thermal or mechanical constraints.
