Product details
Overview
5962-9314901QRA from Texas Instruments is a military-grade octal edge-triggered D-type flip-flop with 3-state outputs, designed for high-reliability bus interface and data latching in aerospace and defense systems. It operates across –55°C to 125°C, delivers ±32-mA high-drive outputs, supports 150-MHz clock frequency, and features low ground bounce (<1 V) at 5 V.
For engineers reviewing the 5962-9314901QRA datasheet, 5962-9314901QRA pinout, 5962-9314901QRA application, or 5962-9314901QRA equivalent, this page provides verified functional identity, military temperature validation, CDIP package mapping, 3-state timing parameters, and direct alternatives for legacy system sustainment and radiation-tolerant design reuse.
Technical Context
The 5962-9314901QRA implements eight independent D-type latches triggered on the positive clock edge, with asynchronous output-enable control enabling high-impedance bus isolation. Its EPIC-IIB BiCMOS process ensures latch-up immunity >500 mA per JESD-17 and ESD protection >2000 V per MIL-STD-883 Method 3015.
It supports TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V), drives loads up to 64 mA sink / –32 mA source, and maintains stable operation under fast input transitions (5 ns/V max). The device retains registered data during output disable, allowing concurrent internal state updates while bus lines remain isolated.

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ABT374FK | LCCC package (20-pin ceramic); identical electrical specs and temp range (–55°C to 125°C) | Better high-frequency performance due to lower package inductance; suited for RF-adjacent digital sections | Select when board-level EMI control or higher-speed routing is required; requires different footprint and reflow profile |
| 5962-9314901QSA | CFP package (20-pin ceramic flat pack); same military spec, identical timing and drive | Lower profile (2.54 mm max height) and improved thermal dissipation vs. CDIP | Prefer for space-constrained chassis-mount applications where vertical clearance is limited |

FAQ
What is the operating temperature range certified for the 5962-9314901QRA?
The 5962-9314901QRA is fully characterized and qualified for continuous operation from –55°C to 125°C per MIL-PRF-38535, with testing performed across that full range for parametric stability, timing, and latch-up immunity - making it suitable for uncontrolled environmental deployments in satellite payloads and jet engine control units.
Does the 5962-9314901QRA support true 5-V TTL interfacing?
Yes, the 5962-9314901QRA supports full 5-V TTL compatibility: input thresholds meet VIL ≤ 0.8 V and VIH ≥ 2.0 V, output VOH ≥ 2.5 V at –3 mA and VOL ≤ 0.55 V at 48 mA, and it drives standard TTL fan-out loads without level-shifting circuitry - confirmed in Section 4 of SCBS111G.
How does the output-enable (OE) function behave during power-up of the 5962-9314901QRA?
To ensure outputs remain in high-impedance during power-up or power-down, OE must be tied to VCC via an external pullup resistor; the minimum value depends on the driver's current-sinking capability, as specified in the Functional Description section of SCBS111G - this prevents bus contention before system initialization completes.
Is the 5962-9314901QRA pin-compatible with commercial SN74ABT374A variants?
No - the 5962-9314901QRA uses a 20-pin CDIP (J package) with military pinout and spacing, whereas commercial SN74ABT374A variants use SOIC (DW), SSOP (DB), or TSSOP (PW) packages with different footprints and thermal characteristics; electrical functionality is identical but mechanical replacement requires PCB redesign.
What is the maximum clock frequency guaranteed for the 5962-9314901QRA across its full temperature range?
The 5962-9314901QRA guarantees 150 MHz maximum clock frequency across its entire –55°C to 125°C operating range, as specified in the Timing Requirements table (page 4 of SCBS111G); typical performance reaches 200 MHz at 25°C, but 150 MHz is the validated worst-case limit for design margining.
