Product details
Overview
5962-9685501Q2A from Texas Instruments is a military-grade octal transparent D-type latch with 3-state outputs, designed for high-reliability aerospace and defense systems. It features TTL-compatible inputs (VIH = 2 V, VIL = 0.8 V), ±25 mA output drive per channel, 5 V supply operation, and operates across –55°C to +125°C. Its latch-enable (LE) and output-enable (OE) controls enable bus-hold functionality in avionics data acquisition subsystems.
For engineers reviewing the 5962-9685501Q2A datasheet, 5962-9685501Q2A pinout, 5962-9685501Q2A application, or 5962-9685501Q2A equivalent, this page delivers verified functional behavior, MIL-PRF-38535 compliance details, LCCC-20 package terminal mapping, timing parameters at extended temperature, and direct alternatives for radiation-tolerant digital interface design.
Technical Context
The 5962-9685501Q2A implements eight independent D-type latches with synchronous LE control and asynchronous OE gating. Each latch captures D-input states on LE falling edge with 1.5 ns minimum hold time and 3.5 ns setup time at 5 V.
Its 3-state outputs support high-impedance bus isolation without pull-up components, while TTL-voltage compatibility enables direct interfacing with legacy 3.3 V microcontrollers driving 5 V backplanes. Latch operation remains functional during OE assertion, allowing data retention or update while outputs are disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | AHCT - TTL-compatible CMOS with 5 V supply only, enabling mixed-voltage system interfacing |
| Operating Temperature | –55°C to +125°C - Qualified per MIL-PRF-38535 for extended-range military platforms |
| Supply Voltage | 4.5 V to 5.5 V - Tight regulation required; no 3.3 V operation supported |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-9685501QRA | CDIP-20 package, same electrical specs and MIL-PRF-38535 Class V qualification | Through-hole mounting; lower thermal resistance but larger board footprint and no hermetic seal | Select when legacy PCB assembly processes or manual repair accessibility are prioritized over weight and vibration performance |
| 5962-9685501QSA | CFP-20 ceramic flatpack, identical timing and drive, qualified to same MIL spec | Side-leaded construction enables easier visual inspection and rework; slightly higher parasitic inductance than LCCC | Choose for systems requiring high-reliability interconnects with simplified test access and thermal management via heatsink attachment |
Compared with 5962-9685501Q2A, the CDIP-20 (5962-9685501QRA) offers mechanical robustness for non-hermetic enclosures, while the CFP-20 (5962-9685501QSA) balances manufacturability and thermal performance-both retain full functional equivalence but differ in mounting method, sealing, and board-level reliability trade-offs.

FAQ
What is the qualified temperature range for the 5962-9685501Q2A?
The 5962-9685501Q2A is fully specified and tested from –55°C to +125°C per MIL-PRF-38535 Class V requirements. All electrical parameters-including propagation delay, setup/hold times, and output drive-are guaranteed across this full range, making it suitable for stratospheric UAVs and space launch vehicle electronics where ambient extremes occur.
Does the 5962-9685501Q2A support 3.3 V supply operation?
No, the 5962-9685501Q2A requires a 4.5 V to 5.5 V supply and does not operate at 3.3 V. Its AHCT logic family is specifically designed for 5 V systems. However, its TTL-compatible inputs accept 3.3 V logic levels (VIH = 2 V min), enabling safe interfacing with 3.3 V controllers while powered from a regulated 5 V rail.
How is the 5962-9685501Q2A pinout arranged in the LCCC-20 package?
The 5962-9685501Q2A uses a top-view LCCC-20 (FK) package with pins numbered counterclockwise starting from the index corner. Pin 1 is OE, pins 2–9 are 1D–8D, pin 10 is GND, pin 11 is LE, pins 12–19 are 8Q–1Q (reversed order), and pin 20 is VCC-matching the official TI FK drawing and MIL-STD-883 test configurations.
Is the 5962-9685501Q2A compliant with MIL-PRF-38535?
Yes, the 5962-9685501Q2A is manufactured and tested to MIL-PRF-38535 Class V requirements, including screening for burn-in, temperature cycling, hermeticity, and parametric testing across the full temperature range. Its device marking "5962-9685501Q2A" explicitly denotes QML-V qualification status.
Can OE and LE be tied together on the 5962-9685501Q2A?
No-OE and LE serve independent functions and must not be shorted. LE controls data latching (transparent vs. hold), while OE controls output state (active vs. high-Z). Tying them together would prevent simultaneous latching and tri-stating, violating the functional truth table and risking bus contention. TI recommends separate control per application timing requirements.
