Product details
Overview
5962-9560601QRA from Texas Instruments is a military-grade octal transceiver with 3-state outputs, designed for bidirectional asynchronous bus communication between A and B data buses. It operates over –55°C to 125°C, features integrated 25-Ω series resistors on B-port outputs to suppress overshoot/undershoot, supports 48 mA A-port sink current and 12 mA B-port sink current, and enters high-impedance state during power-up/down when VCC is below 2.1 V.
For engineers reviewing the 5962-9560601QRA datasheet, 5962-9560601QRA pinout, 5962-9560601QRA application, or 5962-9560601QRA equivalent, key selection considerations include its CDIP-20 ceramic package, MIL-PRF-38535 qualification, 3.4 ns typical propagation delay (A→B), 25-Ω built-in B-port termination, and compatibility with TTL-level control signals in harsh-environment digital systems.
Technical Context
The 5962-9560601QRA implements dual-directional bus transceivers using EPIC-IIB BiCMOS technology, enabling low-power operation while maintaining TTL-compatible input thresholds and 5-V supply robustness. Its DIR input controls data flow direction (A↔B), and OE enables/disables all outputs into high-impedance states independently of direction.
It integrates 25-Ω series resistors exclusively on B-port outputs-verified by schematic and electrical specs-to dampen signal reflections without external components. The device guarantees latch-up immunity >500 mA per JESD-17 and ESD protection >2000 V (MIL-STD-833), making it suitable for mission-critical avionics and defense subsystems requiring proven radiation-tolerant logic interfacing.

FAQ
What is the qualified temperature range for 5962-9560601QRA?
The 5962-9560601QRA is fully characterized and qualified for continuous operation from –55°C to 125°C, meeting MIL-PRF-38535 requirements for extended temperature performance in defense and aerospace platforms. This range is verified across all electrical parameters including propagation delay, output drive, and input thresholds.
Does 5962-9560601QRA have built-in termination resistors?
Yes, the 5962-9560601QRA includes integrated 25-Ω series resistors on all eight B-port outputs, as confirmed in the functional description and schematic diagrams. These resistors reduce overshoot and undershoot without requiring external components, simplifying PCB layout for high-speed bus interfaces.
Is 5962-9560601QRA pin-compatible with commercial SN74ABT2245 variants?
No - while 5962-9560601QRA shares identical logic functionality and pin assignments with SN74ABT2245, its CDIP-20 package has different mechanical dimensions, lead spacing, and soldering requirements than plastic SOIC (DW), SSOP (DB), or TSSOP (PW) packages. Physical interchangeability is not supported.
What is the maximum output sink current on the A port of 5962-9560601QRA?
The A port of 5962-9560601QRA supports a minimum sink current of 48 mA per pin at VCC = 4.5 V, as specified in the recommended operating conditions table. This rating enables direct driving of TTL loads, LEDs, and small-signal relays without additional buffering.
How does 5962-9560601QRA handle power-up sequencing?
When VCC is between 0 V and 2.1 V, the 5962-9560601QRA automatically places all outputs in high-impedance state - preventing bus contention during power ramp-up or brown-out. For guaranteed isolation above 2.1 V, OE must be tied to VCC via an external pullup resistor.
