Texas Instruments 5962-9685801Q2A

Overview

5962-9685801Q2A from Texas Instruments is a military-grade octal buffer/driver with 3-state outputs, designed for bus line driving and memory address register buffering in high-reliability systems. It operates from 4.5 V to 5.5 V, delivers ±8 mA output drive, supports –55°C to +125°C operation, and features dual active-low output-enable inputs (OE1/OE2) for independent 4-bit group control.

For engineers reviewing the 5962-9685801Q2A datasheet, 5962-9685801Q2A pinout, 5962-9685801Q2A application, or 5962-9685801Q2A equivalent, key selection considerations include its LCCC-FK package, MIL-PRF-38535 qualification, TTL-compatible inputs, latch-up immunity (>250 mA), and guaranteed 3-state timing across extended temperature.

Technical Context

The 5962-9685801Q2A implements an 8-channel non-inverting buffer architecture with two independent 3-state control gates-each a 2-input AND with active-low enables-allowing simultaneous or split-group output disable. Its input structure accepts TTL-level signals (VIH = 2 V min, VIL = 0.8 V max) while operating from a 5-V supply.

Output switching is characterized at CL = 15 pF and CL = 50 pF, with propagation delays tPLH/tPHL ≤ 6.5 ns (CL = 15 pF) and enable/disable times tPZH/tPZL ≤ 8.0 ns (CL = 15 pF). The device meets JESD 17 latch-up and JESD 22 ESD specifications (2000-V HBM, 200-V MM, 1000-V CDM).

FAQ

What is the qualified temperature range for the 5962-9685801Q2A?

The 5962-9685801Q2A is fully specified and qualified for operation from –55°C to +125°C. This range is validated per MIL-PRF-38535 Class V requirements and applies to all DC and AC parameters including propagation delay, output drive, and 3-state timing. No derating is required within this span, making the 5962-9685801Q2A suitable for extreme-environment deployment where commercial-grade buffers would fail.

Does the 5962-9685801Q2A require external pull-up resistors on OE pins?

Yes - to ensure defined high-impedance state during power-up or brownout, OE1 and OE2 should each be tied to VCC through a pull-up resistor. TI recommends a value ≤10 kΩ to guarantee fast, noise-immune assertion while staying within the input leakage current limit (±1 µA). This practice prevents unintended output activation before system initialization completes, which is critical in fault-tolerant 5962-9685801Q2A deployments.

How does the dual OE architecture of the 5962-9685801Q2A improve system-level bus management?

The 5962-9685801Q2A's separate OE1 and OE2 inputs allow independent control of Y1–Y4 and Y5–Y8 output groups. This enables time-multiplexed bus sharing - for example, using OE1 to gate address lines while OE2 controls data lines - reducing external logic and eliminating race conditions during bus handoff. In systems with multiple masters, this feature simplifies arbitration without adding discrete gates, directly enhancing determinism in the 5962-9685801Q2A's target applications.

Is the 5962-9685801Q2A RoHS compliant?

The 5962-9685801Q2A uses a POST-PLATE finish per TI's Package Option Addendum and is not classified as RoHS-compliant under EU Directive 2011/65/EU due to lead content in the solderable terminations. It is exempt under Annex III for high-reliability military/aerospace applications. Customers requiring RoHS compliance should evaluate commercial equivalents like SN74AHCT541DBR, but note these lack MIL-PRF-38535 qualification and extended temperature support.

What is the maximum capacitive load the 5962-9685801Q2A can drive while maintaining specified timing?

The 5962-9685801Q2A is characterized for CL = 15 pF and CL = 50 pF loads. At CL = 50 pF, tPLH/tPHL increases to ≤9.5 ns and tPZH/tPZL to ≤12 ns - still within guaranteed limits across –55°C to +125°C. Driving >50 pF risks violating setup/hold windows in high-speed buses; for heavier loads, TI recommends verifying timing margins with actual board parasitics or adding series termination. This load capability is integral to the 5962-9685801Q2A's role in backplane and long-trace military interconnects.
