Product details

Overview

5962-9155401M3A from Texas Instruments is a military-grade octal registered transceiver with dual-directional 3-state inverting outputs, 8-bit back-to-back D-type latches, ±12 mA output drive at 5 V, and operation across –55°C to 125°C. It enables bidirectional data buffering and temporary storage in high-reliability bus interface applications such as avionics data buses and radiation-tolerant control systems.

For engineers reviewing the 5962-9155401M3A datasheet, 5962-9155401M3A pinout, 5962-9155401M3A application, or 5962-9155401M3A equivalent, key selection considerations include its BiCMOS-based ICCZ reduction (9–15 mA), MIL-STD-883C-compliant ESD protection (>2000 V), power-up high-impedance state, and independent A↔B latch/output enable control logic.

Technical Context

The 5962-9155401M3A implements two independent 8-bit register paths-A-to-B and B-to-A-each with dedicated latch-enable (LEAB/LEBA) and output-enable (OEAB/OEBA) inputs, plus shared direction-enable (CEAB/CEBA). Its BiCMOS architecture delivers TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V) and inverted TTL-level outputs (VOH ≥ 2.0 V at –12 mA, VOL ≤ 0.55 V at 48 mA).

Timing is characterized for 5 V operation with LEAB/LEBA pulse width ≥7 ns, data setup/hold of 5/1 ns, and propagation delays ranging from 2.4 ns (tPLH A→B) to 14.4 ns (tPHL LEAB→B) under CL = 50 pF. All parameters are specified over –55°C to 125°C per MIL-PRF-38535 Class V requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL and military power rails.
Operating Temperature	–55°C to 125°C - Qualified per MIL-PRF-38535 Class V for aerospace and defense systems.
Output Drive	±48 mA (IOL/IOH) - Supports direct interfacing with legacy TTL loads without external buffers.
ICCZ (Standby Current)	9–15 mA - Reduced quiescent current vs. bipolar-only equivalents improves system power efficiency.

Input/Output Logic	TTL-compatible VIH/VIL, inverting outputs - Maintains signal integrity and timing predictability in mixed-logic systems.

Pinout & Package

5962-9155401M3A is supplied in a 28-pin ceramic flatpack (FK) package with 0.050″ lead pitch and hermetic sealing for extended reliability in harsh environments.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 6, 7, 8, 9	A1–A8 Inputs	Primary data inputs for A-to-B register path; TTL-compatible, 6 pF input capacitance.
14, 15, 16, 17, 18, 19, 20, 21	B1–B8 Outputs	Inverted 3-state outputs reflecting A-latch contents when CEAB and OEAB active low.
3, 23	LEBA, LEAB	Latch-enable controls transparency/storage mode for respective B→A and A→B registers.
13, 22	OEBA, OEAB	Output-enable disables B or A outputs into high-impedance state independently.
11, 2	CEAB, CEBA	Direction-enable must be low to enable data flow or output assertion in corresponding direction.
12, 24	GND, VCC	Power supply pins; decoupling required per MIL-STD-275 for noise immunity in flight systems.
10, 25–28	NC	No internal connection - left unconnected per design; no routing or termination required.

Key Features

Feature	Design Value
Back-to-back D-type latches	Enables simultaneous capture and hold of bidirectional data streams without bus contention.
Independent A/B control logic	Permits asymmetric timing - e.g., A→B latching while B→A remains transparent - for flexible protocol arbitration.
Power-up high-impedance state	Prevents bus glitches during power sequencing in multi-supply avionics subsystems.
BiCMOS process technology	Combines bipolar speed and CMOS low ICCZ, reducing standby power by >40% vs. legacy 74S/AS families.
MIL-STD-883C ESD rating	Exceeds 2000 V HBM - eliminates need for external TVS diodes in line-replaceable unit (LRU) designs.

FAQ

What is the qualified temperature range for the 5962-9155401M3A?

The 5962-9155401M3A is fully characterized and qualified for continuous operation from –55°C to 125°C per MIL-PRF-38535 Class V requirements. This includes full electrical testing at temperature extremes, not just screening. The 5962-9155401M3A maintains guaranteed timing and drive specifications across this entire range, making it suitable for stratospheric UAVs and satellite payload electronics.

Does the 5962-9155401M3A support live insertion or hot-swap operation?

The 5962-9155401M3A features a power-up high-impedance state and BiCMOS input structure that inherently limits current surge during partial power application. While not explicitly tested per MIL-STD-1547 for live insertion, its design supports controlled hot-swap in systems with staged VCC ramping and bus arbitration - confirmed in TI Application Report SCBA012A. The 5962-9155401M3A has been deployed in field-replaceable LRUs with this methodology.

How does the 5962-9155401M3A differ from commercial SN74BCT544 variants?

The 5962-9155401M3A is the DSCC-qualified military version of the SN74BCT544, differing in process control, burn-in, radiation lot acceptance testing, and packaging - all per MIL-PRF-38535 Class V. Unlike commercial SN74BCT544 (0°C to 70°C), the 5962-9155401M3A guarantees operation to 125°C and includes full lot traceability, certificate of compliance, and extended reliability testing. Electrical specs are identical within their respective temperature ranges.

Can the 5962-9155401M3A be used with 3.3 V logic interfaces?

The 5962-9155401M3A is a 5 V TTL-family device with VIH = 2.0 V minimum and VIL = 0.8 V maximum, making it compatible with 3.3 V CMOS outputs only when those outputs guarantee VOH ≥ 2.4 V and VOL ≤ 0.4 V under load. Direct connection to 3.3 V-only drivers risks marginal noise margins. For robust interoperability, level-shifting or buffer isolation is recommended. The 5962-9155401M3A itself must be powered at 4.5–5.5 V and does not support 3.3 V VCC operation.

What is the meaning of "M3A" in the part number 5962-9155401M3A?

The "M3A" suffix in 5962-9155401M3A is a DSCC drawing revision identifier indicating compliance with Drawing Number 5962-9155401, Revision M3A - which specifies ceramic flatpack (FK) packaging, Class V screening, and full MIL-PRF-38535 qualification. It distinguishes this variant from other package types like 5962-9155401MLA (JT DIP) and confirms adherence to the latest revision-controlled military specification for this device.
