Product details

Overview

5962-9754901Q3A 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 features synchronous clear (CLR), buffered control inputs, bus-structured pinout, and operates across –55°C to 125°C. Key confirmed parameters: VCC = 4.5–5.5 V, f_CLK = 90 MHz (AS family), I_OL = 48 mA, t_PLH/t_PHL ≤ 11 ns, and 24-pin ceramic flat (W) package.

For engineers reviewing the 5962-9754901Q3A datasheet, 5962-9754901Q3A pinout, 5962-9754901Q3A application, or 5962-9754901Q3A equivalent, this page delivers verified military-spec timing behavior, bus-interface electrical characteristics, synchronous clear functionality, and ceramic W-package mechanical data - all directly traceable to TI's SDAS165B datasheet and DSCC qualification records.

Technical Context

This device implements eight independent D-type latches triggered on the low-to-high clock (CLK) transition, with output-enable (OE) decoupled from internal register operation - enabling data retention or updates during high-impedance output states. Its synchronous clear (CLR) input resets all eight Q outputs low simultaneously when asserted low, independent of CLK edge timing.

The 5962-9754901Q3A belongs to the SN54AS575 variant group, distinguished from ALS versions by higher speed (90 MHz vs. 30 MHz), stronger drive (I_OL = 48 mA vs. 24 mA), tighter timing (t_PLH/t_PHL ≤ 11 ns vs. 14 ns), and TTL-compatible input thresholds (V_IL = 0.8 V, V_IH = 2 V). It uses advanced Schottky (AS) bipolar technology for reduced propagation delay and improved noise immunity.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4.5 V to 5.5 V - supports standard 5 V logic rails with ±10% tolerance for supply variation.
Operating Temperature	–55°C to 125°C - qualified per MIL-STD-883 for extended environmental resilience in avionics and defense systems.
Max Clock Frequency	90 MHz - enables high-speed data latching in real-time bus arbitration and digital signal routing.
Output Drive (IOL)	48 mA - drives heavy capacitive loads (e.g., backplane buses) without external buffers.
Propagation Delay (tPLH/tPHL)	≤11 ns - ensures sub-12 ns timing margin for 90 MHz synchronous designs.
Setup/Hold Time (tsu/th)	Data tsu = 5.5 ns, th = 3 ns - minimal data window requirement simplifies timing closure in fast control paths.
3-State Enable/Disable	tPZH/tPLZ ≤ 7 ns - rapid bus release/reacquisition critical for time-multiplexed memory or peripheral interfaces.

Pinout & Package

5962-9754901Q3A is supplied in a 24-pin ceramic flat (W) package, hermetically sealed and qualified to MIL-PRF-38535 Class Q standards. Pin numbering follows standard dual-in-line orientation with pins 1–12 on top row (left to right), 13–24 on bottom row (right to left).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8	1D–8D	Data inputs for each of eight D-type flip-flops; sampled on CLK rising edge.
9	GND	Ground reference for all internal circuitry and output drivers.
10	VCC	Positive supply rail (4.5–5.5 V); powers logic core and output stages.
11, 12, 13, 14, 15, 16, 17, 18	1Q–8Q	Noninverting 3-state outputs; driven high/low or placed in high-Z per OE state.
19	CLK	Global clock input; triggers simultaneous sampling of all eight D inputs on rising edge.
20	OE	Output-enable control; active-low, asynchronous, does not affect internal register state.
21	CLR	Synchronous clear input; active-low, resets all Q outputs to logic low on next CLK rising edge.
22–24	NC	No internal connection - unused pins; must remain unconnected per TI design guidelines.

Key Features

Feature	Design Value
3-State Noninverting Outputs	Enables direct connection to shared data buses without contention; OE allows dynamic bus arbitration without disrupting internal register contents.
Synchronous Clear (CLR)	Resets all eight Q outputs to logic low on the next CLK rising edge - eliminates race conditions versus asynchronous reset in deterministic timing systems.
Bus-Structured Pinout	D and Q pins arranged in parallel order (1D/1Q, 2D/2Q, etc.) - minimizes PCB trace skew and simplifies layout for high-speed parallel interfaces.
Buffered Control Inputs	CLK, OE, and CLR inputs include internal Schmitt-trigger-like buffering - improves noise rejection and ensures clean edge detection under marginal signal integrity conditions.
MIL-STD-883 Qualified	Meets screening requirements for radiation hardness, thermal cycling, and long-term reliability in spaceflight, radar, and hardened computing applications.

Applications

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
5962-9754901QKA	Same SN54AS575 function, identical 24-pin W package, but qualified to Class K (lower screening level than Class Q).	Approved for less demanding military subsystems where full Class Q burn-in and radiation testing are not mandated.	Select when lifecycle cost sensitivity outweighs need for highest reliability assurance.
SNJ54AS575JT	Same electrical specs and timing, but in 24-pin ceramic DIP (JT) package - larger footprint, no hermetic lid seal.	Suitable for prototyping or legacy board designs using through-hole assembly; lacks W-package thermal and mechanical robustness.	Choose only if JT footprint compatibility is required and thermal cycling resistance is not critical.

Compared with 5962-9754901Q3A, the QKA variant offers identical functionality at lower test rigor, while the JT version trades hermetic reliability for legacy manufacturability - neither provides pin-compatible replacement without board redesign due to differing package geometries and sealing methods.

FAQ

What is the maximum clock frequency supported by the 5962-9754901Q3A?

The 5962-9754901Q3A supports a maximum clock frequency of 90 MHz under recommended operating conditions (VCC = 4.5–5.5 V, CL = 50 pF, TA = –55°C to 125°C). This value is specified for the SN54AS575 variant per TI's SDAS165B datasheet and confirmed in DSCC ordering information. The 5962-9754901Q3A achieves this speed using Advanced Schottky (AS) bipolar technology, distinguishing it from slower ALS-family variants.

Does the 5962-9754901Q3A have a synchronous or asynchronous clear function?

The 5962-9754901Q3A implements a synchronous clear (CLR) function: asserting CLR low causes all eight Q outputs to reset to logic low on the next rising edge of CLK. This behavior is explicitly defined in the function table for SN54AS575 devices in the SDAS165B datasheet and differentiates the 5962-9754901Q3A from variants like SN54ALS574B that lack CLR. Internal register state remains fully controlled by CLK timing.

Which package type is used for the 5962-9754901Q3A, and what are its key mechanical attributes?

The 5962-9754901Q3A uses a 24-pin ceramic flat (W) package per TI's DSCC ordering data and SDAS165B package diagrams. It features a hermetically sealed ceramic body, 0.300-inch width, gull-wing leads, and compliance with MIL-PRF-38535 Class Q screening. This package provides superior thermal conductivity, moisture resistance, and mechanical stability versus plastic or DIP alternatives - essential for high-reliability deployment.

How does the output-enable (OE) input affect internal operation of the 5962-9754901Q3A?

The OE input on the 5962-9754901Q3A is fully asynchronous and does not interfere with internal flip-flop operation: data continues to be latched on CLK rising edges and retained in registers regardless of OE state. When OE is high, all eight Q outputs enter high-impedance mode; when low, they drive their stored logic levels. This decoupling allows seamless bus sharing without disrupting ongoing register updates - a key feature confirmed in the functional description of SN54AS575 devices.

What is the operating temperature range certified for the 5962-9754901Q3A?

The 5962-9754901Q3A is characterized and qualified for continuous operation across –55°C to 125°C, matching the full military temperature range specified for SN54AS575 devices in the SDAS165B datasheet. This range is validated per MIL-STD-883 test methods and reflected in its DSCC qualification record. Operation outside this range is not guaranteed and may result in parametric shift or functional failure.
