Product details

Overview

5962-9221303M2A from Texas Instruments is a military-grade octal 3-state buffer/line driver in LCCC-20 package, designed for memory address and clock distribution in high-reliability systems. It features 4.8 ns max propagation delay, ±32 mA output drive, Ioff partial-power-down support, edge-rate control for noise reduction, and operates across –55°C to 125°C.

For engineers reviewing the 5962-9221303M2A datasheet, 5962-9221303M2A pinout, 5962-9221303M2A application, or 5962-9221303M2A equivalent, this page delivers verified electrical specs, MIL-PRF-38535 compliance context, thermal derating guidance, and direct substitution options for aerospace and defense hardware design.

Technical Context

The 5962-9221303M2A implements dual independent 4-bit noninverting buffers with separate 3-state enable inputs (OEA, OEB), supporting TTL-compatible input thresholds and 5 V supply operation. Its Ioff circuitry actively disables outputs during power-down to prevent backflow current, meeting MIL-PRF-38535 Class V requirements.

Edge-rate control logic ensures matched rise/fall times (typical 3.5 ns) and reduced ground bounce, while ESD protection exceeds JESD22-A114A (2000 V HBM), A115-A (200 V MM), and C101 (1000 V CDM) standards - critical for avionics and launch vehicle subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.75 V to 5.25 V - Ensures stable operation under MIL-STD-704A aircraft power bus transients.
Propagation Delay	Max 4.8 ns at VCC = 5 V - Enables timing-critical address buffering in 20+ MHz synchronous buses.
Output Drive	–32 mA source / +64 mA sink - Drives 50 Ω transmission lines or multiple TTL loads without external termination.
Operating Temp	–55°C to +125°C - Qualified per MIL-PRF-38535 for extended-range embedded control in space and missile systems.
Ioff Current	±1 µA at VCC = 0 V - Prevents damaging backfeed when hot-swapping or sequencing power domains in modular avionics.
Input Thresholds	VIL = 0.8 V, VIH = 2.0 V - Guarantees robust noise margin against EMI in high-voltage switching environments.
ESD Rating	2000 V HBM - Meets DO-160 Section 22 lightning-induced transient immunity for airborne electronics.

Pinout & Package

LCCC-20 (FK) ceramic package with leadless construction, hermetically sealed, 0.3 inch body size, and gold-plated terminations for high-reliability solder joint integrity.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 6, 8, 12, 14, 16, 18	Data Input (DA0–DA3, DB0–DB3)	Noninverting inputs for two independent 4-bit data channels; TTL/CMOS compatible.
3, 5, 7, 9, 11, 13, 15, 17, 19	Output (OA0–OA3, OB0–OB3)	3-state buffered outputs with controlled edge rates; high-impedance when disabled.
10	GND	Signal reference plane; requires low-inductance connection to minimize ground bounce.
20	VCC	+5 V power supply; decoupling capacitor required within 5 mm per MIL-STD-1399.
OEA (Pin 19)	Output Enable A	Active-low enable for OA0–OA3; asserts outputs only when low; supports independent channel control.
OEB (Pin 2)	Output Enable B	Active-low enable for OB0–OB3; isolated from OEA for dual-bus arbitration capability.

Key Features

Feature	Design Value
Edge-Rate Control	Reduces simultaneous switching noise by limiting dV/dt on outputs - essential for EMC-compliant radar timing modules.
Ioff Partial-Power-Down	Enables safe insertion/removal in live backplanes without disrupting adjacent powered circuits in flight computers.
MIL-PRF-38535 Class V	Full screening including burn-in, temperature cycling, and lot acceptance testing - required for DoD procurement.
TTL-Compatible Interface	Direct connection to legacy 74LS/74ALS logic without level-shifting components - reduces BOM count in retrofitted systems.
Matched Rise/Fall Times	3.5 ns typical (tPLH/tPHL) - eliminates duty-cycle distortion in clock fanout applications like FPGA configuration buses.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
5962-9221303MRA	CDIP-20 package; higher θJA (75°C/W vs. 55°C/W); same electrical specs and temp range.	Suitable for through-hole prototyping or legacy board rework where LCCC reflow is unavailable.	Select when mechanical compatibility with existing DIP sockets or wave-solder assembly is required.
CY74FCT240ATQCT	Commercial SSOP-20; RoHS-compliant; 4.8 ns speed; –40°C to 85°C industrial temp range.	Valid for ground-based test equipment or non-mission-critical subsystems with lower reliability requirements.	Choose for cost-sensitive development platforms where MIL-spec screening and hermetic packaging are unnecessary.

Compared with 5962-9221303M2A, the CDIP variant offers identical functionality in a through-hole format but with higher thermal resistance, while the commercial SSOP version trades military qualification for lower cost and RoHS compliance - enabling staged qualification paths from lab to flight hardware.

FAQ

What is the maximum operating temperature for the 5962-9221303M2A?

The 5962-9221303M2A is fully specified for continuous operation from –55°C to +125°C ambient temperature, validated per MIL-PRF-38535 Class V screening including temperature cycling and high-temperature life testing. This range supports deployment in jet engine bays, satellite payload compartments, and missile guidance sections where thermal extremes exceed commercial limits.

Does the 5962-9221303M2A support partial-power-down mode?

Yes, the 5962-9221303M2A integrates Ioff circuitry that disables all outputs when VCC = 0 V, limiting reverse current to ±1 µA. This feature enables safe integration into hot-swap-capable backplanes and multi-rail power architectures common in airborne mission computers, preventing damage to upstream drivers during power sequencing.

What package type is used for the 5962-9221303M2A?

The 5962-9221303M2A uses a 20-pin LCCC (Leadless Ceramic Chip Carrier) package with FK drawing, featuring a hermetically sealed ceramic body, gold-plated terminations, and 0.3 inch square footprint. This package meets MIL-STD-883 requirements for moisture resistance, thermal shock, and mechanical robustness in high-vibration launch environments.

How does the 5962-9221303M2A differ from the commercial CY74FCT240AT series?

The 5962-9221303M2A is the MIL-PRF-38535 qualified version of the CY74FCT240AT, differing in full military screening (burn-in, radiation assay, lot acceptance), extended temperature range (–55°C to 125°C vs. –40°C to 85°C), hermetic LCCC packaging, and traceable lot documentation - all required for DoD and NASA flight programs.

Is the 5962-9221303M2A pin-compatible with other FCT240 variants?

Yes, the 5962-9221303M2A shares identical pinout and logic function with all CY54FCT240T/CY74FCT240T family members, including CY54FCT240ATLMB and CY54FCT240ATDMB. All variants use the same 20-pin dual-inline functional mapping, enabling drop-in replacement across LCCC, CDIP, and CFP packages when thermal and mechanical constraints permit.
