Product details

Overview

5962-9214701MRA from Texas Instruments is a military-grade octal noninverting buffer/line driver with dual 4-bit channels, 3-state outputs, ±32-mA high-drive capability, latch-up immunity >500 mA, and operation across −55°C to 125°C - deployed in memory address buffering, clock distribution, and bus-transceiver interfaces within avionics and hardened control systems.

For engineers reviewing the 5962-9214701MRA datasheet, 5962-9214701MRA pinout, 5962-9214701MRA application, or 5962-9214701MRA equivalent, this page delivers verified military-spec electrical parameters, CDIP-J package mechanical data, OE-controlled 3-state timing behavior, and direct alternatives for legacy system sustainment and radiation-tolerant design reuse.

Technical Context

This device implements two independent 4-bit noninverting buffers with separate active-low output-enable (OE) inputs per channel. Each buffer passes A-inputs to Y-outputs when OE is low; outputs enter high-impedance state when OE is high. Input logic thresholds are TTL-compatible (VIL = 0.8 V, VIH = 2.0 V), supporting direct interfacing with legacy 5-V logic families.

Designed using EPIC-II^B BiCMOS process, it achieves low ground bounce (<1 V VOLP), high noise immunity (2000-V HBM ESD), and robust latch-up resistance per JESD-17. Power-up/down sequencing requires OE tied to VCC via pullup resistor to guarantee defined high-Z state during supply transients.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - compatible with standard 5-V TTL/CMOS rails; absolute max 7 V prevents damage during transient overvoltage.
Output Drive	−32 mA IOH / +64 mA IOL - enables direct driving of heavy capacitive loads (e.g., >50-pF buses) without external buffers.
Propagation Delay	tPLH/tPHL ≤ 4.3 ns @ VCC = 5 V, CL = 50 pF - supports >100-MHz bus toggle rates in synchronous memory and address paths.
Operating Temperature	−55°C to +125°C - qualified per MIL-PRF-38535 Class B for deployment in missile guidance, satellite payload, and engine control units.
Input Clamp Current	−18 mA IIK - protects against negative input excursions (e.g., ESD or crosstalk) without requiring external diodes.
3-State Enable Timing	tPZL ≤ 5.6 ns, tPHZ ≤ 5.6 ns - ensures fast, deterministic bus release and acquisition critical for time-critical arbitration protocols.
Quiescent Current	ICC ≤ 250 µA (disabled), ≤30 mA (active) - enables low-power standby while maintaining full drive strength on demand.

Pinout & Package

Ceramic Dual-In-Line Package (CDIP) with 20 leads, hermetically sealed, 0.300-inch wide body, 0.100-inch lead pitch, and gold-plated leads compliant with MIL-STD-883. Designed for through-hole mounting and high-reliability board assembly in aerospace and defense platforms.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 19	Channel 1 Output Enable (active-low)	Controls Y1–Y4; must be pulled high during power-up to prevent bus contention.
2OE, 2	Channel 2 Output Enable (active-low)	Independent control of Y1–Y4 outputs; enables asymmetric channel gating.
1A1–1A4, 3,5,7,9	Channel 1 Data Inputs	Noninverting inputs routed directly to corresponding Y outputs when OE low.
2A1–2A4, 11,13,15,17	Channel 2 Data Inputs	Electrically isolated from Channel 1; supports dual-bus isolation or mirrored signal paths.
1Y1–1Y4, 18,16,14,12	Channel 1 Outputs	3-state CMOS outputs with symmetrical drive; share common GND (Pin 10) and VCC (Pin 20).
2Y1–2Y4, 1,4,6,8	Channel 2 Outputs	Matched drive strength and timing to Channel 1; enables load-balanced bus drivers.
GND, 10	Ground Reference	Single ground pin for both channels; layout requires low-inductance connection to minimize ground bounce.
VCC, 20	Power Supply	5-V supply input; decoupling capacitor required within 1 cm to suppress switching noise.

Key Features

Feature	Design Value
High-Drive 3-State Outputs	±32-mA/±64-mA drive enables direct termination of long PCB traces and multi-drop buses without signal integrity degradation.
Military Temperature Range	−55°C to +125°C operation validated per MIL-PRF-38535 ensures reliability in jet engine bays and space vacuum environments.
Latch-Up Immunity	Exceeds 500 mA per JESD-17 - eliminates risk of destructive latch-up during voltage transients in avionics power domains.
Low Ground Bounce	VOLP < 1 V at 5 V/25°C - maintains logic threshold margins under simultaneous output switching, critical for mixed-signal co-location.
TTL-Compatible Inputs	VIL = 0.8 V, VIH = 2.0 V - allows seamless integration with legacy 5-V microcontrollers, FPGAs, and ASICs without level-shifting.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54ABT244J	Identical die, same CDIP-J package, identical military temperature range and qualification baseline.	No functional difference; SNJ54ABT244J is the TI manufacturer-marked version of the same device.

FAQ

What is the operating temperature range specified for the 5962-9214701MRA?

The 5962-9214701MRA is characterized for continuous operation from −55°C to +125°C, fully qualified per MIL-PRF-38535 Class B for use in extreme-environment applications such as jet engine controllers and satellite attitude control systems. This range is validated across all electrical parameters including propagation delay, drive strength, and 3-state leakage.

Does the 5962-9214701MRA require external pull-up resistors on its OE pins?

Yes - to ensure the outputs remain in high-impedance state during power-up or brownout conditions, both 1OE (Pin 19) and 2OE (Pin 2) must be tied to VCC via external pull-up resistors. The minimum value depends on the current-sinking capability of the driving source; TI recommends ≥10-kΩ for typical TTL-compatible control logic interfacing with the 5962-9214701MRA.

Is the 5962-9214701MRA pin-compatible with commercial-grade SN74ABT244A variants?

No - although functionally identical, the 5962-9214701MRA uses a 20-pin CDIP-J package with 0.300-inch width and gold-plated leads, whereas commercial SN74ABT244A variants use SOIC-DW, SSOP-DB, or TSSOP-PW packages with different pin pitches, body sizes, and solder profiles. PCB layout and assembly processes are not interchangeable.

What is the maximum capacitive load the 5962-9214701MRA can drive while maintaining specified timing?

The 5962-9214701MRA's switching characteristics are guaranteed with CL = 50 pF, as tested per JEDEC standards. While it can drive heavier loads (e.g., 100 pF) due to its ±64-mA low-side drive, propagation delay increases linearly with capacitance - at 100 pF, tPHL rises to ~7.5 ns. For designs exceeding 50 pF, IBIS simulation using the official 5962-9214701MRA model is recommended.

How does the latch-up immunity of the 5962-9214701MRA compare to standard commercial logic devices?

The 5962-9214701MRA exceeds 500 mA latch-up immunity per JEDEC JESD-17, significantly surpassing typical commercial ABT devices (e.g., SN74ABT244A), which are rated only to 200 mA. This robustness is achieved via EPIC-II^B BiCMOS process enhancements and is verified across the full −55°C to +125°C range - essential for systems exposed to power rail transients in airborne platforms.
