Overview
The Texas Instruments 5962-9685501QRA is a military-grade, octal transparent D-type latch with three-state outputs. It belongs to the SN54AHCT series, utilizing CMOS technology with TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting in a 20-pin CDIP package. It functions as a single circuit logic component with non-inverting polarity, designed for high-reliability applications across an extended temperature range from -55°C to +125°C.
Feature Summary
- Octal transparent D-type latch architecture providing eight independent data storage elements
- Three-state output capability enabling direct bus interfacing and system flexibility
- TTL-compatible input thresholds ensuring seamless integration with legacy digital systems
- Military-grade construction supporting operation in extreme environmental conditions
Applications
- High-reliability aerospace and defense data acquisition systems
- Industrial control interfaces requiring robust signal latching
- Military communication equipment bus drivers
- Harsh environment computing memory buffers
Procurement Notes
Verify authenticity through authorized distributors or certified suppliers due to the component's military specification status. Confirm that the part number matches the exact SNJ54AHCT573J.A marking. Ensure packaging integrity is maintained to prevent damage to the ceramic dual in-line package during handling and installation.
Selection Notes
Select this component when a transparent latch with three-state outputs is required for MIL-STD compliant designs. It serves as the latch counterpart to the SN54AHCT374 flip-flop. Choose this part over commercial variants if extended temperature ranges and radiation hardness are mandatory for the specific application environment.
Part Context
This part is the military version of the SN54AHCT573. It shares functional equivalence with commercial SN74AHCT573 devices but meets stricter manufacturing and testing standards. It is distinct from the SN54AHCT374, which is an edge-triggered flip-flop rather than a transparent latch.
Replacement Considerations
Direct equivalent: SNJ54AHCT573J. Commercial alternative: SN74AHCT573 (verify temperature and reliability requirements). Cross-reference with SN54AHCT574 for flip-flop functionality if latching behavior differs.
