Texas Instruments 5962-9754301VSA

Overview

5962-9754301VSA from Texas Instruments is a military-grade octal bus transceiver with tri-state outputs, designed for 2.7-V to 3.6-V V_CC operation in mixed-voltage 3.3-V/5-V systems. It features direction control (DIR), output enable (OE), bus-hold on all data inputs, I_off for live insertion, and 6.3 ns max propagation delay at 3.3 V. It serves as a bidirectional level translator in high-reliability aerospace and defense computing backplanes.

For engineers reviewing the 5962-9754301VSA datasheet, 5962-9754301VSA pinout, 5962-9754301VSA application, or 5962-9754301VSA equivalent, key selection criteria include its MIL-PRF-38535 compliance, –55°C to +125°C operating range, 5.5-V tolerant inputs, and verified 20-pin ceramic flatpack (FK) package with validated pin mapping per JESD51-14 thermal standard.

Technical Context

The 5962-9754301VSA implements an asynchronous bidirectional data path between two 8-bit buses using a single DIR signal to determine transmission direction (A→B or B→A), while OE independently controls tri-state output enable/disable. Its I_off circuitry actively blocks current flow during partial power-down, preventing back-drive damage when V_CC = 0 V.

Bus-hold circuitry maintains valid logic states on floating A/B port inputs without external resistors, and input clamping diodes support 5.5-V tolerance across the full temperature range. All parameters are 100% tested per MIL-PRF-38535 requirements, including latch-up (>250 mA per JESD17) and ESD robustness (2000-V HBM, 1500-V CDM).

FAQ

What is the operating temperature range for the 5962-9754301VSA?

The 5962-9754301VSA is rated for –55°C to +125°C operation and fully tested across this range per MIL-STD-883 Method 1010. This makes it suitable for extreme environments such as jet engine compartments, satellite thermal vacuum chambers, and desert-deployed electronic warfare systems. The 5962-9754301VSA maintains specified t_pd, I_off, and bus-hold performance throughout this full military temperature span.

Does the 5962-9754301VSA support 5-V input signals while powered from a 3.3-V supply?

Yes, the 5962-9754301VSA accepts input voltages up to 5.5 V regardless of V_CC level, enabling direct interfacing with legacy 5-V TTL devices without external level shifters. This mixed-mode capability is intrinsic to its input structure and is verified across –55°C to +125°C. The 5962-9754301VSA leverages internal clamping diodes and robust oxide design to sustain this voltage differential safely.

How does the bus-hold feature work on the 5962-9754301VSA, and why is it valuable?

The 5962-9754301VSA integrates active bus-hold circuitry on all A1–A8 and B1–B8 inputs, providing ±75 µA holding current at V_CC = 3 V to maintain valid logic states on unterminated or floating lines. This eliminates external pull-up/pull-down resistors - critical in dense backplane layouts where resistor placement causes parasitic loading. The 5962-9754301VSA's bus-hold remains active regardless of OE or DIR state, ensuring deterministic behavior during configuration transitions.

Is the 5962-9754301VSA compatible with hot-swap or live-insertion systems?

Yes, the 5962-9754301VSA incorporates I_off circuitry that limits input/output leakage to ±20 µA when V_CC = 0 V, preventing damaging back-drive currents during card insertion or removal. This feature is fully characterized per MIL-PRF-38535 and enables safe use in field-replaceable units (LRUs) within airborne and naval platforms. The 5962-9754301VSA requires no external circuitry to achieve compliant live-insertion behavior.

What package type and pinout does the 5962-9754301VSA use?

The 5962-9754301VSA is supplied exclusively in a 20-pin ceramic flatpack (FK package), with standardized pin assignments matching the SN54LVCH245A family: DIR on Pin 1, A1–A8 on Pins 2–9, GND on Pin 10, B1–B8 on Pins 11–18, OE on Pin 19, and V_CC on Pin 20. This pinout is identical across all QML-V variants and enables mechanical and electrical interchangeability in existing FK-footprint designs.
