Product details

Overview

5962-9754901QLA from Texas Instruments is a military-grade octal D-type edge-triggered flip-flop with 3-state noninverting outputs, designed for bus driving in high-reliability systems. It operates across –55°C to 125°C, features synchronous clear (CLR), clock-triggered data capture on CLK↑, and supports 24 mA low-level output drive at 5 V. It is used in avionics I/O port buffering and radiation-tolerant data acquisition subsystems.

For engineers reviewing the 5962-9754901QLA datasheet, 5962-9754901QLA pinout, 5962-9754901QLA application, or 5962-9754901QLA equivalent, this device serves as a TTL-compatible, bus-structured register with buffered control inputs, high-impedance output enable, and MIL-STD-883 Class B compliance - critical for deterministic timing in embedded control and test instrumentation.

Technical Context

This device implements eight independent D-type latches synchronized to the rising edge of CLK, with separate asynchronous output-enable (OE) and synchronous clear (CLR) controls. All inputs are TTL-compatible, and outputs drive standard TTL loads directly without external pull-ups.

The internal architecture includes buffered OE and CLR inputs, bus-structured pinout for minimal trace skew, and 3-state output drivers capable of sinking 24 mA while maintaining VOL ≤ 0.4 V at VCC = 4.5 V. Propagation delays are specified down to 3 ns (tPLH) under loaded conditions (CL = 50 pF).

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4.5 V to 5.5 V - compatible with standard 5 V logic rails and tolerant of supply ripple in ruggedized power domains.
Operating Temperature	–55°C to 125°C - qualified per MIL-PRF-38535 for use in aerospace, defense, and downhole electronics.
Output Drive (IOL)	24 mA - sufficient to drive eight standard TTL inputs or terminate unterminated stubs on backplanes.
Max Clock Frequency	90 MHz - enables high-speed data latching in real-time digital signal routing applications.
tPLH / tPHL	3 ns / 4 ns - ensures tight setup/hold margins in synchronous bus interfaces with sub-10 ns timing windows.
3-State Enable/Disable	tPZH = 2 ns, tPLZ = 2 ns - allows rapid bus arbitration and glitch-free multiplexing in shared-data-path architectures.
Input Compatibility	TTL - interoperable with legacy 74-series logic, microcontroller GPIOs, and discrete level-shifting circuits.

Pinout & Package

Ceramic flat package (W), 24-pin, 0.300-inch wide, hermetically sealed, compliant with MIL-STD-883.

Pin/Terminal	Circuit Role	Design Meaning
1	CLR	Synchronous clear input - drives all eight Q outputs low when asserted low concurrent with CLK↑.
2	OE	Output-enable control - places all Q outputs in high-impedance state without affecting internal latch states.
3–10	1D–8D	Data inputs - routed directly to D inputs of respective flip-flops; no internal inversion.
11	GND	Ground reference - dedicated pin for low-noise return path in mixed-signal environments.
12	VCC	Power supply - decoupling capacitor placement adjacent to this pin is required for stable switching.
13–20	1Q–8Q	Noninverting 3-state outputs - each independently controllable via OE; true bus-driving capability.
21	CLK	Clock input - edge-sensitive rising transition triggers simultaneous sampling of all eight D inputs.
22–24	NC	No internal connection - unused pins; must remain unconnected per TI design guidelines.

Key Features

Feature	Design Value
Bus-structured pinout	Minimizes PCB trace length mismatch between parallel D/Q lines - critical for skew-controlled data buses.
Synchronous clear (CLR)	Resets all eight outputs to logic low in one clock cycle without disrupting ongoing OE-controlled bus sharing.
Buffered control inputs	Reduces capacitive loading on system-level control lines - improves noise immunity and fan-out capability.
3-state noninverting outputs	Enables direct connection to shared data buses without external transceivers or direction-control logic.
MIL-STD-883 Class B screening	Includes burn-in, temperature cycling, and parametric testing - ensures reliability in mission-critical deployments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal D-type 3-state flip-flop applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
5962-9754901QKA	Same die, W-package, but with different DSCC screening lot traceability and minor packaging marking variation.	Identical functional and timing behavior; approved for same Class B applications.	Select when cross-referencing legacy procurement documentation referencing QKA suffix.
SNJ54AS575JT	Ceramic DIP (JT) package, 24-pin, same electrical specs and temperature range, but larger footprint and lower thermal dissipation rating.	Suitable for prototyping or legacy board replacements where W-package rework is impractical.	Choose for manual assembly or repair scenarios where surface-mount W-package handling is constrained.

Compared with 5962-9754901QLA, the QKA variant offers identical performance with alternate DSCC traceability, while the JT-packaged SNJ54AS575 trades compactness and thermal efficiency for through-hole compatibility - making the QLA optimal for new high-density, high-reliability designs requiring hermetic sealing and minimal board area.

FAQ

What is the operating temperature range for the 5962-9754901QLA?

The 5962-9754901QLA is characterized for operation from –55°C to 125°C, meeting full military temperature range requirements per MIL-PRF-38535. This specification is verified through temperature cycling and parametric testing across the range, ensuring reliable performance in extreme environmental conditions encountered in aerospace and defense platforms. The 5962-9754901QLA maintains specified timing and drive strength throughout this range.

Does the 5962-9754901QLA support synchronous reset functionality?

Yes, the 5962-9754901QLA includes a synchronous clear (CLR) input that resets all eight Q outputs to logic low on the next rising edge of CLK when CLR is held low. This behavior is confirmed in the function table and logic diagram of the SDAS165B datasheet. Unlike asynchronous reset, the 5962-9754901QLA's CLR does not affect outputs outside the clock edge, preserving timing determinism in synchronous systems.

What package type is used for the 5962-9754901QLA?

The 5962-9754901QLA uses a ceramic flat (W) package - a 24-pin, 0.300-inch wide, hermetically sealed outline compliant with MIL-STD-883. This package provides superior moisture resistance, thermal stability, and mechanical robustness compared to plastic or DIP variants. Pin configuration matches the W-package top view shown in Figure 1 of the SDAS165B datasheet.

Can the 5962-9754901QLA drive standard TTL loads directly?

Yes, the 5962-9754901QLA can drive standard TTL loads directly: its outputs source ≥2.4 V at –2.6 mA (VOH) and sink up to 24 mA while maintaining VOL ≤ 0.4 V, satisfying TTL input voltage thresholds. This eliminates need for external buffers in bus-driving applications. The 5962-9754901QLA's 3-state outputs further allow direct connection to shared data buses without contention.

Is the 5962-9754901QLA pin-compatible with commercial-grade SN74AS575 devices?

No - the 5962-9754901QLA uses a 24-pin W-package with NC pins at positions 22–24, whereas commercial SN74AS575 variants use DW or NT packages with different pin counts and assignments. While logic function and electrical behavior align with SN74AS575, physical layout, thermal characteristics, and screening differ significantly. Direct PCB replacement requires redesign; the 5962-9754901QLA is not a drop-in substitute for commercial packages.
