Overview
The Texas Instruments 5962-9321801QRA is an ABT series octal transparent D-type latch featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels. The device provides eight non-inverting inputs and outputs, with high-level output current of -8 mA and low-level output current of 8 mA. It utilizes a 20-pin CDIP package for through-hole mounting. The component functions reliably across an extended temperature range from -55°C to +125°C.
Feature Summary
- Octal transparent D-type latch architecture with three-state outputs
- ABT series CMOS technology compatible with TTL input logic levels
- Extended industrial temperature operation capability
Applications
- High-reliability military aerospace data storage systems
- Industrial control interface buffering
- Ruggedized communication equipment signal latching
Procurement Notes
Verify the specific suffix QRA indicates qualified reliability standards required for your application. Confirm the CDIP-20 package compatibility with your assembly process. Ensure the ABT series electrical characteristics meet your system timing requirements. Validate that the manufacturer documentation aligns with your procurement specifications before finalizing orders.
Selection Notes
Select this component when an octal latch with three-state bus driving capability is required in a ceramic DIP package. The ABT series offers speed advantages over standard AHCT variants while maintaining TTL compatibility. Consider the extended temperature range if operating in harsh environments. Verify pinout compatibility with existing board layouts designed for SN54ABT373 equivalents.
Part Context
This part belongs to the SN54/74ABT373 family of octal transparent D-type latches. The 5962 prefix denotes a military-grade or high-reliability variant manufactured by Texas Instruments. It serves as a radiation-hardened or screened alternative to commercial logic families, ensuring stability in demanding operational conditions where standard commercial parts may fail.
Replacement Considerations
Direct functional substitutes include SN54ABT373J and SN54AHCT374M. Verify pin compatibility and electrical parameters before substitution. The 5962-9686501QRA is an AHCT variant with different input thresholds.
