Product details
Overview
5962-9685301QRA from Texas Instruments is a military-grade octal edge-triggered D-type flip-flop with 3-state outputs, designed for bus interface and register applications in high-reliability systems. It operates from –55°C to +125°C at 4.5–5.5 V, delivers ±8 mA output drive, features TTL-compatible inputs (VIH = 2 V, VIL = 0.8 V), and supports 110 ns max propagation delay (CL = 15 pF) in CDIP-20 packaging.
For engineers reviewing the 5962-9685301QRA datasheet, 5962-9685301QRA pinout, 5962-9685301QRA application, or 5962-9685301QRA equivalent, this page provides verified functional mode behavior, timing constraints (tsu = 3.5 ns, th = 1.5 ns), output-enable control logic, and military-grade thermal and ESD specifications per MIL-PRF-38535.
Technical Context
The 5962-9685301QRA implements eight independent D-type latches synchronized to the rising edge of CLK, with simultaneous 3-state control via active-low OE. Its TTL-voltage-compatible inputs allow direct interfacing with legacy 3.3-V or 5-V logic while maintaining full 5-V CMOS output swing (VOH ≥ 3.8 V, VOL ≤ 0.44 V at IOL = 8 mA).
It exhibits latch-up immunity exceeding 250 mA per JESD 17, ESD protection of 2000-V HBM and 1000-V CDM, and operates across the full military temperature range (–55°C to +125°C) with supply voltage tolerance up to 7 V absolute maximum - enabling use in avionics, ground radar, and hardened communications subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Octal transparent D-type latch with 3-state outputs - enables synchronous data capture and bus isolation |
| Supply Voltage | 4.5–5.5 V - compatible with regulated 5-V military power rails; absolute max 7 V prevents damage during transients |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 for deployment in extreme-environment platforms |
| Propagation Delay | 110 ns max (CL = 15 pF) - ensures timing margin in 8-MHz+ synchronous bus interfaces |
| Output Drive | ±8 mA per output - sufficient to drive 50-pF loads with controlled edge rates, minimizing ringing on long traces |
| Input Compatibility | TTL-level (VIH = 2 V, VIL = 0.8 V) - allows direct connection to legacy 3.3-V microcontrollers without level shifters |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets MIL-STD-883 Class 3015.8 for handling in non-classified assembly environments |
Pinout & Package
5962-9685301QRA is supplied in a 20-pin Ceramic Dual-In-Line Package (CDIP-J), with 0.3-inch body width, through-hole mounting, and hermetic sealing suitable for high-reliability aerospace and defense applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives all eight Q outputs into high-impedance state when high; enables bidirectional bus arbitration |
| 2–9 (1D–8D) | Data inputs | Asynchronous D inputs latched on CLK rising edge; TTL-compatible thresholds simplify mixed-voltage design |
| 10 (GND) | Ground reference | Common return path for logic and output current; must be low-inductance connection in noise-sensitive systems |
| 11 (CLK) | Clock input | Rising-edge-triggered; synchronizes all eight latches simultaneously; input transition rate limited to 20 ns/V |
| 12–19 (8Q–1Q) | 3-state outputs | Non-inverting buffered outputs; each capable of sourcing/sinking ±8 mA into capacitive or resistive loads |
| 20 (VCC) | Power supply | 5-V nominal supply; bypass capacitor required near pin to suppress switching noise coupling into analog sections |
Key Features
| Feature | Design Value |
|---|---|
| Latch-up immunity | Exceeds 250 mA per JESD 17 - eliminates risk of destructive latch-up during voltage transients or ESD events |
| Slow edge control | Controlled output slew rate minimizes overshoot/undershoot on unterminated transmission lines up to 15 cm |
| Military qualification | Fully compliant with MIL-PRF-38535 Class V - includes screening, burn-in, and lot traceability for flight-critical systems |
| Overvoltage-tolerant inputs | Accepts VI up to 5.5 V regardless of VCC - enables safe hot-swap or mixed-rail debugging without external clamping |
| High-impedance isolation | Outputs present <1 µA leakage in disabled state - prevents loading of shared buses during processor reset or sleep modes |
Applications
| Avionics Data Bus Interface | Ground-Based Radar Timing Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54AHCT574J | Identical electrical specs and CDIP-20 package; same MIL-PRF-38535 Class V qualification; differs only in device marking format | No functional difference; both rated for –55°C to +125°C and qualified to same military screening standards | Select SNJ54AHCT574J if legacy BOM references that part number; otherwise 5962-9685301QRA is functionally identical and actively stocked |
| 5962-9685301Q2A | LCCC-20 ceramic package instead of CDIP; same logic, timing, and temperature specs; different mechanical footprint and soldering process | Suitable for surface-mount PCBs requiring higher density or improved thermal conduction; not pin-compatible due to different land pattern | Choose 5962-9685301Q2A only when board layout mandates LCCC; requires redesign of footprint and reflow profile |
Compared with SNJ54AHCT574J, 5962-9685301QRA offers identical functionality and qualification but updated device marking and orderable ID; compared with 5962-9685301Q2A, it provides through-hole compatibility and simplified assembly for legacy military hardware upgrades.

FAQ
What is the operating temperature range of the 5962-9685301QRA?
The 5962-9685301QRA is fully specified and tested from –55°C to +125°C per MIL-PRF-38535 Class V requirements. This range is validated across all electrical parameters including propagation delay, output drive, and input thresholds - ensuring reliable operation in jet engine bays, missile guidance sections, and desert-deployed radar enclosures where ambient temperatures exceed 100°C.
Does the 5962-9685301QRA support 3.3-V input logic levels?
Yes, the 5962-9685301QRA accepts 3.3-V logic levels directly: its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) ensure robust recognition of 3.3-V high/low states when powered from 5-V VCC. No external level shifter is needed, simplifying interface design with modern low-voltage FPGAs and microcontrollers while maintaining full 5-V output swing.
What is the maximum clock frequency supported by the 5962-9685301QRA?
The 5962-9685301QRA supports a maximum clock frequency of approximately 8.3 MHz, derived from its 110 ns maximum propagation delay (tPLH/tPHL) under CL = 15 pF load conditions. At higher capacitance (e.g., CL = 50 pF), fmax drops to ~7.5 MHz. System designers must verify timing margins against actual trace capacitance and ensure setup/hold times (tsu = 3.5 ns, th = 1.5 ns) are met in their specific layout.
How does the output-enable (OE) pin function on the 5962-9685301QRA?
The OE pin on the 5962-9685301QRA is active-low: when OE = LOW, all eight Q outputs reflect the latched D-input values; when OE = HIGH, all Q outputs enter high-impedance state, electrically disconnecting the device from the bus. This enables clean bus sharing among multiple devices - for example, allowing one 5962-9685301QRA to drive while others remain tri-stated during multi-drop communication cycles.
Is the 5962-9685301QRA RoHS-compliant?
The 5962-9685301QRA is not RoHS-compliant in the standard EU definition, as it uses leaded solder in its hermetic CDIP package per MIL-PRF-38535 requirements. However, it complies with DoD Directive 4140.01 and is approved for use in U.S. Department of Defense systems where lead-free exemptions apply. TI provides full material declarations upon request for compliance documentation.
