Texas Instruments 5962-9314701Q2A

Overview

5962-9314701Q2A from Texas Instruments is a military-grade octal edge-triggered D-type flip-flop with 3-state outputs, designed for high-capacitance bus driving in avionics and defense systems. It operates across –55°C to 125°C, delivers ±32-mA high-drive outputs (IOH/IOL), features EPIC-II^B BiCMOS architecture for low power dissipation, and supports 125-MHz clock frequency with 1.6-ns setup/hold timing.

For engineers reviewing the 5962-9314701Q2A datasheet, 5962-9314701Q2A pinout, 5962-9314701Q2A application, or 5962-9314701Q2A equivalent, this device serves as a latch-controlled bidirectional bus interface with output-enable–gated high-impedance state, critical for MIL-STD-883 qualified embedded control and data acquisition subsystems.

Technical Context

This device implements eight independent positive-edge-triggered D flip-flops with asynchronous output-enable control. Each channel latches D-input logic on CLK rising edge and drives complementary Q outputs, while OE independently places all eight outputs into high-Z without affecting internal storage.

Its EPIC-II^B BiCMOS process enables TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V), rail-to-rail output swing (VOH ≥ 2.5 V at –32 mA, VOL ≤ 0.55 V at 64 mA), and latch-up immunity exceeding 500 mA per JESD-17 - essential for ruggedized digital backplanes.

FAQ

What is the operating temperature range of the 5962-9314701Q2A?

The 5962-9314701Q2A is characterized for operation from –55°C to 125°C, fully compliant with MIL-PRF-38535 Class V environmental screening requirements. This range ensures reliable functionality in extreme aerospace and defense environments, including stratospheric UAV platforms and missile guidance electronics where thermal cycling exceeds civilian specifications.

Does the 5962-9314701Q2A support 3.3-V logic interfacing?

No, the 5962-9314701Q2A is strictly a 5-V device with TTL-compatible input thresholds (VIH = 2 V min, VIL = 0.8 V max) and requires VCC = 4.5 V to 5.5 V. It does not support 3.3-V signaling directly; level-shifting circuitry is required when interfacing with 3.3-V FPGAs or microcontrollers to avoid input undervoltage or output overvoltage conditions.

How does the output-enable (OE) pin affect internal flip-flop operation in the 5962-9314701Q2A?

The OE pin in the 5962-9314701Q2A controls only the output drivers - it has no effect on internal latch states or clocked data capture. While OE is asserted high (disabling outputs), the eight D flip-flops continue to sample and store D-input data on each CLK rising edge, preserving register contents and enabling seamless bus re-engagement without data loss or reset sequencing.

What is the maximum clock frequency supported by the 5962-9314701Q2A?

The 5962-9314701Q2A supports a maximum clock frequency of 125 MHz under recommended operating conditions (VCC = 5 V, TA = 25°C), with guaranteed timing margins verified across the full –55°C to 125°C range. Its tPLH/tPHL propagation delays remain ≤6.1 ns, ensuring robust timing closure in high-throughput digital control applications such as radar pulse generation sequencers.

Is the 5962-9314701Q2A pin-compatible with commercial-grade SN74ABT534A variants?

No - although electrically identical in function and AC/DC parameters, the 5962-9314701Q2A uses a 20-pin LCCC (FK) package with ceramic body and J-leads, whereas SN74ABT534A variants use plastic SOIC (DW), SSOP (DB), or PDIP (N) packages. Mechanical dimensions, soldering profiles, and thermal characteristics differ significantly; PCB layout and assembly processes are not interchangeable.
