Product details
Overview
5962-9051601M2A from Texas Instruments is a military-grade octal edge-triggered D-type latch with 3-state outputs, designed for high-reliability bus interface and register applications in aerospace and defense systems. It operates from 4.5 V to 5.5 V, features BiCMOS architecture, delivers ±64 mA output drive (IOL), supports 70 MHz clock frequency, and is qualified per MIL-PRF-38535 Class V.
For engineers reviewing the 5962-9051601M2A datasheet, 5962-9051601M2A pinout, 5962-9051601M2A application, or 5962-9051601M2A equivalent, key selection criteria include its LCCC-20 package, –55°C to +125°C operating range, 3-state bus-driving capability, and full compliance with SNJ54BCT374 specifications for radiation-hardened embedded control.
Technical Context
The 5962-9051601M2A implements eight independent D-type flip-flops synchronized on the rising edge of CLK, with asynchronous 3-state control via OE. Its BiCMOS design enables low ICCZ (5–8 mA) while maintaining TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and fast propagation delays (tPLH/tPHL ≤ 11.6 ns).
All eight outputs support high-impedance disable independent of internal latch state, allowing data retention during bus contention. The device meets JESD22-A114A ESD protection (2000-V HBM) and is fully characterized across temperature for IOL = 64 mA, VOL ≤ 0.55 V, and VOH ≥ 2.4 V at IOH = –15 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with legacy 5-V TTL and military power rails. |
| Operating Temperature | –55°C to +125°C - Qualified for extreme-environment avionics, guidance, and space-qualified electronics. |
| Output Drive (IOL) | 64 mA - Sufficient to directly drive heavily loaded data buses without external buffers. |
| Max Clock Frequency | 70 MHz - Supports high-speed register transfer in real-time control subsystems. |
| Propagation Delay | tPLH/tPHL ≤ 11.6 ns - Enables tight timing margins in synchronous digital systems. |
| 3-State Enable Delay | tPZH/tPLZ ≤ 12.7 ns - Guarantees clean bus release/activation for multi-master arbitration. |
| Input Clamp Current | –18 mA - Protects inputs against transient overvoltage events in harsh EMI environments. |
Pinout & Package
LCCC-20 ceramic package (FK) with side-brazed leads, hermetically sealed, 0.300-inch square body, 0.200-inch height, and leadless construction for high-reliability mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Data Inputs (1D–8D) | Asynchronous parallel data inputs latched on CLK↑; TTL-compatible voltage thresholds. |
| 9 | Output Enable (OE) | Active-low control: drives all Q outputs to high-Z when high; no effect on internal latch state. |
| 10 | GND | Signal ground reference for all logic and output stages. |
| 11 | VCC | Positive supply rail (4.5–5.5 V); decoupling required per MIL-STD-1399. |
| 12, 13, 14, 15, 16, 17, 18, 19 | Outputs (1Q–8Q) | 3-state buffered outputs capable of sinking 64 mA or sourcing –15 mA; bus-ready drive. |
| 20 | CLK | Edge-sensitive clock input; triggers simultaneous latching of all eight D inputs on rising edge. |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS Process Technology | Reduces ICCZ to 5–8 mA while retaining TTL-level drive strength and noise immunity. |
| Full Parallel Load Architecture | Enables simultaneous capture of 8-bit data words on single CLK edge-ideal for address/data registers. |
| Buffered Control Inputs | OE input buffered to minimize loading on upstream logic and ensure clean enable/disable transitions. |
| High-Impedance Output State | Outputs draw <50 µA in Z-state-eliminates need for pull-up resistors or bus terminators in shared-bus designs. |
| MIL-PRF-38535 Class V Qualification | Includes screening for burn-in, temperature cycling, and radiation tolerance per military specification. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-latch with 3-state output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54BCT374FK | Identical die, identical LCCC-20 package, same MIL-PRF-38535 Class V qualification; differs only in top-side marking format. | No functional difference; used interchangeably in DoD BOMs where part number traceability is managed via lot code rather than full PN. | Select when procurement requires TI's standard military marking convention (SNJ54BCT374FK) versus Defense Logistics Agency (DLA) assigned 5962-9051601M2A. |
| 5962-8776001RA | Same function but uses older bipolar TTL process; higher ICCZ (12 mA), slower tPLH (15 ns), and lower IOL (40 mA). | Suitable for legacy upgrades where timing margin exists, but not for new designs requiring 70 MHz operation or low-power standby. | Choose only for backward compatibility in fielded systems where redesign is prohibited; avoid for new avionics or radar programs. |
Compared with 5962-9051601M2A, SNJ54BCT374FK offers identical performance and qualification with alternate marking, while 5962-8776001RA trades speed and efficiency for proven legacy reliability-making the former a direct logistics alternative and the latter a constrained retrofit option.

FAQ
What is the qualified temperature range for the 5962-9051601M2A?
The 5962-9051601M2A is fully specified and tested from –55°C to +125°C per MIL-PRF-38535 Class V requirements. All electrical parameters-including propagation delay, output drive, and input thresholds-are guaranteed across this range, making it suitable for high-altitude flight control and space-qualified electronics where thermal cycling is severe.
Does the 5962-9051601M2A support true bidirectional bus operation?
The 5962-9051601M2A does not support bidirectional data flow on individual pins-it is an octal D-type latch with unidirectional data path (D→Q) and separate 3-state control (OE). However, it enables bidirectional bus systems when paired with complementary devices (e.g., transceivers or dual-direction latches), as its high-impedance outputs prevent bus contention during direction changes.
How is the 5962-9051601M2A different from commercial SN74BCT374 variants?
The 5962-9051601M2A shares identical logic functionality and pinout with SN74BCT374 but is manufactured under MIL-PRF-38535 Class V with enhanced screening: 100% burn-in, extended temperature testing, radiation hardness assurance, and hermetic LCCC packaging. Commercial variants lack these qualifications and operate only from 0°C to +70°C.
Can the 5962-9051601M2A be used without external pull-up resistors on OE?
Yes-OE is internally buffered and TTL-compatible, but to guarantee high-impedance state during power-up/power-down, TI recommends tying OE to VCC via a pull-up resistor (value determined by driver sink capability). This prevents undefined output states that could cause bus contention in multi-device systems.
Is the 5962-9051601M2A RoHS-compliant?
The 5962-9051601M2A uses post-plated lead finish on its LCCC-20 package and is exempt from RoHS lead restrictions under EU Directive 2011/65/EU Annex III for high-reliability aerospace and defense applications. It complies with MIL-STD-1288 for outgassing and is approved for use in manned spacecraft and critical flight hardware.
