Product details
Overview
5962-8763101RA from Texas Instruments is a military-grade octal D-type edge-triggered flip-flop with 3-state outputs, operating over −55°C to 125°C, supporting 4.5–5.5 V supply, 10 ns max propagation delay at 5 V, and TTL-compatible inputs. It serves as a bus-oriented register or I/O port in radiation-tolerant avionics and defense computing systems.
For engineers reviewing the 5962-8763101RA datasheet, 5962-8763101RA pinout, 5962-8763101RA application, or 5962-8763101RA equivalent, key selection criteria include its CDIP-20 package, guaranteed operation across extended military temperature range, 3-state output drive capability (±24 mA), and compatibility with high-capacitance bus loads without external pull-ups.
Technical Context
The 5962-8763101RA implements eight independent D-type latches triggered on the positive clock edge, with asynchronous 3-state control via OE. Its internal logic retains data during output disable, enabling concurrent register update and bus release.
Designed for MIL-PRF-38535 Class V compliance, it features input voltage tolerance up to 5.5 V, absolute maximum ratings including ±20 mA clamp current and −0.5 V to 7 V supply range, and specified timing parameters (e.g., 5 ns min CLK pulse width, 5.5 ns max setup time) validated across −55°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures stable operation under regulated 5 V military power rails with ±10% tolerance. |
| Propagation Delay (tpd) | 10 ns max at 5 V - Enables reliable 70 MHz clock operation in synchronous bus interfaces. |
| Output Drive (IOL/IOH) | ±24 mA - Directly drives 50 Ω transmission lines or 15+ TTL loads without buffers. |
| Operating Temperature | −55°C to 125°C - Qualified for engine bay, radar, and space-qualified chassis environments. |
| Input Compatibility | TTL-voltage compatible - Interfaces directly with legacy 5 V TTL logic without level shifters. |
| 3-State Leakage (IOZ) | ±0.25 μA at 5.5 V - Minimizes bus leakage current when outputs are disabled, critical for low-power standby modes. |
| Setup/Hold Time | 5.5 ns / 1.5 ns - Defines minimum data stability window before and after CLK rising edge for deterministic sampling. |
Pinout & Package
5962-8763101RA is housed in a 20-pin Ceramic Dual In-line Package (CDIP-J), hermetically sealed for moisture resistance and thermal stability in harsh environments. Pin 10 is GND, Pin 11 is VCC, and the device uses standard dual-row through-hole mounting with 0.3-inch body width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Data Inputs (D1–D8) | Asynchronous parallel data inputs sampled on CLK↑; tolerate up to 5.5 V regardless of VCC. |
| 9 | Output Enable (OE) | Active-low control: asserts high-impedance state on all Q outputs without affecting internal latch state. |
| 10 | GND | Power ground reference for all internal logic and output drivers. |
| 11 | VCC | Positive supply rail (4.5–5.5 V); supports simultaneous switching of all eight outputs. |
| 12, 13, 14, 15, 16, 17, 18, 19 | Outputs (Q1–Q8) | 3-state buffered outputs capable of sourcing/sinking ±24 mA; enter high-Z when OE = high. |
| 20 | CLK | Positive-edge-triggered clock input; requires ≥5 ns pulse width and meets TTL input thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| Extended Temperature Operation | Validated performance from −55°C to 125°C ensures reliability in jet engine controllers and satellite payload electronics. |
| Bus-Friendly 3-State Outputs | High-impedance state eliminates bus contention and removes need for external pull-up resistors in shared-data architectures. |
| TTL-Compatible Inputs | Accepts standard 0 V/5 V logic levels, enabling direct interface with legacy military subsystems without translation circuitry. |
| Robust Absolute Ratings | Withstands −0.5 V to 7 V supply and input transients, protecting against power sequencing faults and ESD events. |
| Controlled Output Transition | Specified tPZL/tPHZ (≤9 ns) and tPLZ/tPHZ (≤10.5 ns) ensure predictable bus release timing in time-critical arbitration protocols. |

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 |
|---|---|---|---|
| SNJ54ACT374FK | LCCC-20 ceramic package; lower thermal resistance (θJA ≈ 50°C/W vs. CDIP's 75°C/W); identical electrical specs. | Better suited for high-density, conduction-cooled modules where board space and thermal mass are constrained. | Select SNJ54ACT374FK when PCB layout requires surface-mount footprint and enhanced thermal dissipation. |
| 5962-8763101SA | CFP-20 metal-ceramic package; higher mechanical robustness; same temp range and timing, but different lead finish (Call TI). | Preferred for vibration-prone platforms (e.g., missile guidance) due to superior shock resistance and hermeticity. | Choose 5962-8763101SA for applications demanding MIL-STD-883 vibration qualification beyond standard CDIP requirements. |
Compared with 5962-8763101RA, SNJ54ACT374FK offers superior thermal performance in compact layouts, while 5962-8763101SA provides enhanced mechanical survivability-both retain identical logic functionality and military temperature rating but differ in package form factor and mounting method.

FAQ
What is the maximum clock frequency supported by the 5962-8763101RA?
The 5962-8763101RA supports a maximum clock frequency of 70 MHz across its full −55°C to 125°C operating range, as confirmed by timing characterization in the SCAS539F datasheet. This limit derives from worst-case propagation delay (10 ns) and setup/hold timing margins. At 25°C, it can operate up to 100 MHz, but system-level design must use the 70 MHz rating for guaranteed military-spec compliance.
Does the 5962-8763101RA require external pull-up resistors on its 3-state outputs?
No, the 5962-8763101RA does not require external pull-up resistors on its Q outputs. Its 3-state outputs present high impedance (IOZ ≤ ±0.25 μA) when OE is high, eliminating bus loading. Pull-up resistors are only recommended on the OE pin itself (tied to VCC) to ensure defined high-impedance state during power-up/power-down sequences.
Is the 5962-8763101RA compliant with MIL-PRF-38535 Class V?
Yes, the 5962-8763101RA is manufactured and tested to MIL-PRF-38535 Class V requirements, as indicated by its 5962- prefix and CDIP-J packaging. All electrical parameters-including propagation delay, setup/hold time, and output drive-are fully characterized and tested across −55°C to 125°C per the specification.
Can the 5962-8763101RA interface directly with 3.3 V logic systems?
The 5962-8763101RA accepts input voltages up to 5.5 V and is TTL-compatible, but its outputs swing rail-to-rail between GND and VCC (4.5–5.5 V). Direct connection to 3.3 V logic requires level-shifting circuitry or series resistors to avoid overstressing downstream inputs; it is not 3.3 V I/O compatible without external interface components.
What is the recommended PCB layout practice for minimizing noise coupling on the 5962-8763101RA's CLK and OE pins?
For the 5962-8763101RA, place 0.1 μF ceramic decoupling capacitors between VCC and GND within 5 mm of pins 11 and 10. Route CLK (pin 20) and OE (pin 9) as short, guarded traces-avoid routing adjacent to noisy signals-and terminate CLK with a 33 Ω series resistor near the driver to dampen ringing. Ground plane continuity beneath the CDIP footprint is essential for signal integrity.
