Product details
Overview
5962-9680601QRA from Texas Instruments is a military-grade octal inverting buffer/driver with tri-state outputs, organized as two independent 4-bit sections (1A–1Y and 2A–2Y), operating over –55°C to +125°C at 4.5 V–5.5 V supply, with TTL-compatible inputs and 8 mA output drive capability-used in high-reliability bus interface and memory address driver applications.
For engineers reviewing the 5962-9680601QRA datasheet, 5962-9680601QRA pinout, 5962-9680601QRA application, or 5962-9680601QRA equivalent, key selection considerations include its CDIP-20 package, MIL-PRF-38535 compliance, guaranteed operation across extended temperature, input voltage tolerance up to 5.5 V, and propagation delay ≤9.5 ns (CL = 15 pF) under full military conditions.
Technical Context
The 5962-9680601QRA implements dual 4-bit inverting logic paths with independent output-enable controls (1OE and 2OE), enabling selective tri-state control of each 4-bit group. Its CMOS design ensures low static current (ICC ≤40 µA) while maintaining TTL-level input thresholds (VIH = 2 V, VIL = 0.8 V) for seamless 3.3 V-to-5 V level translation.
Each output delivers ±8 mA drive strength into resistive loads and supports high-impedance states with leakage ≤±2.5 µA. The device features slow edge rates to suppress ringing on transmission lines and meets JESD17 latch-up immunity (>250 mA), making it suitable for noise-sensitive aerospace and defense bus systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - supports stable operation across MIL-STD power rail tolerances |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 for harsh-environment deployment |
| Propagation Delay | ≤9.5 ns (CL = 15 pF) - enables timing-critical address/data bus buffering in real-time systems |
| Output Drive | ±8 mA - sufficient to drive multiple TTL loads without external buffers |
| Input Compatibility | TTL-voltage compatible (VIH = 2 V, VIL = 0.8 V) - interoperable with legacy 5 V logic families |
| Tri-State Leakage | ±2.5 µA max - ensures minimal bus contention during high-impedance mode |

Pinout & Package
5962-9680601QRA is supplied in a hermetically sealed Ceramic Dual-In-Line Package (CDIP), 20-pin, with 0.300-inch wide body and through-hole mounting. Pin 10 is GND; Pin 20 is VCC; Pins 1 and 19 are active-low output enables (1OE, 2OE); Pins 2–9 and 11–18 are bidirectional I/O pairs (1A1–1Y4, 2A1–2Y4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE | Active-low enable for Group 1 (1A1–1Y4) | Drives all four Y outputs low when asserted; high-Z when deasserted |
| 1A1–1A4 | Inverting input group 1 | Accepts TTL/CMOS logic; inverted signal appears on corresponding 1Yn |
| 1Y1–1Y4 | Inverting output group 1 | Delivers complement of 1An; tri-stated when 1OE = high |
| 2OE | Active-low enable for Group 2 (2A1–2Y4) | Independent control of second 4-bit channel; no crosstalk with Group 1 |
| 2A1–2A4 | Inverting input group 2 | Electrically isolated from Group 1; supports parallel bus expansion |
| 2Y1–2Y4 | Inverting output group 2 | Provides separate buffered path; enables dual-bus or redundant signaling |
| GND (Pin 10) | Ground reference | Primary return path; must be low-inductance connection for noise immunity |
| VCC (Pin 20) | Power supply | Requires local 0.1 µF ceramic bypass capacitor per TI layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Extended temperature range | –55°C to +125°C operation verified per MIL-PRF-38535 screening and testing |
| TTL-input compatibility | Guaranteed VIH = 2 V / VIL = 0.8 V allows direct interfacing with legacy 5 V TTL logic |
| Controlled edge rate | Slower transitions minimize EMI and overshoot on long PCB traces or cables |
| Latch-up immunity | Exceeds 250 mA per JESD17 - critical for survivability in radiation-prone platforms |
| High-impedance isolation | Outputs fully disconnect from bus when OE is high; leakage < ±2.5 µA prevents loading |
Applications
| Avionics Data Bus Interface | Military Vehicle Control System |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54AHCT240J | Same CDIP-20 package, identical pinout and electrical specs; differs only in part numbering convention and lot trace format | No functional difference; both qualified to MIL-PRF-38535 Class B with identical screening | Select SNJ54AHCT240J if sourcing from legacy TI military distribution channels requiring legacy nomenclature |
| 5962-9680601Q2A | LCCC-20 ceramic package instead of CDIP-20; same die, temp range, and logic function; different thermal resistance (RθJA = 48.9°C/W vs 54.9°C/W) | Better high-frequency performance due to lower inductance leads; preferred for >100 MHz clock distribution | Choose 5962-9680601Q2A when board space is constrained and superior RF grounding is required |
Compared with SNJ54AHCT240J, 5962-9680601QRA offers identical functionality in the same CDIP package but with updated documentation and traceability; versus 5962-9680601Q2A, it trades slightly higher thermal resistance for easier manual soldering and legacy board compatibility.

FAQ
What is the maximum operating temperature for the 5962-9680601QRA?
The 5962-9680601QRA is rated for continuous operation from –55°C to +125°C, fully qualified per MIL-PRF-38535 screening requirements. This specification is validated across all electrical parameters including propagation delay, output drive, and leakage current, ensuring reliable performance in jet engine bays, missile guidance sections, and other extreme thermal environments where the 5962-9680601QRA is routinely deployed.
Does the 5962-9680601QRA support 3.3 V logic inputs?
Yes, the 5962-9680601QRA accepts 3.3 V logic inputs reliably due to its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and overvoltage tolerance up to 5.5 V. This allows direct connection to 3.3 V microcontrollers without level shifters, making the 5962-9680601QRA ideal for mixed-voltage systems such as modern avionics where legacy 5 V buses interface with newer low-voltage processors.
Is the 5962-9680601QRA pin-compatible with commercial SN74AHCT240 variants?
No-the 5962-9680601QRA uses a CDIP-20 package with 0.300-inch lead spacing, whereas commercial SN74AHCT240 variants use SOIC, TSSOP, SSOP, or PDIP packages with different footprints and thermal characteristics. While the logic function, pin functions, and electrical behavior are identical, PCB layout and soldering processes differ significantly; the 5962-9680601QRA requires dedicated CDIP-compatible land patterns and reflow profiles.
What is the purpose of the two separate output-enable pins (1OE and 2OE) on the 5962-9680601QRA?
The 5962-9680601QRA features independent 1OE and 2OE pins to enable selective tri-state control of its two 4-bit groups-allowing one group (e.g., 1A1–1Y4) to drive a bus while the other (2A1–2Y4) remains high-Z. This capability supports time-division multiplexing, fault-isolation schemes, and dual-bus architectures in safety-critical systems where the 5962-9680601QRA serves as a configurable interface element.
How does the 5962-9680601QRA handle unused inputs?
All unused inputs on the 5962-9680601QRA must be tied to either VCC or GND to prevent floating nodes that cause excessive supply current, oscillation, or undefined output states. TI explicitly recommends pull-up resistors on OE pins during power-up to ensure high-impedance default; for unused A inputs, tying to GND is preferred to minimize dynamic power. This requirement is critical for achieving specified ICC ≤40 µA and avoiding latch-up in the 5962-9680601QRA's military-grade implementation.
