5962-9853001Q2A

Overview

The Texas Instruments 5962-9853001Q2A is a military-grade octal D-type edge-triggered flip-flop featuring a clear function and 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 an extended temperature range from -55°C to +125°C. Key electrical parameters include a propagation delay of 10.4 ns, high-level output current of -8 mA, and low-level output current of 8 mA. It is housed in a 20-pin CDIP package.

Feature Summary

Octal configuration providing eight independent D-type flip-flops with edge triggering for parallel data storage.
Integrated asynchronous clear function allows immediate resetting of all flip-flop outputs regardless of clock state.
Three-state outputs enable direct connection to bus systems without additional buffering hardware.
TTL-compatible input logic levels facilitate seamless interfacing with standard digital control circuits.

Applications

Military aerospace data acquisition systems requiring radiation-hardened or high-reliability components
Avionics memory registers for flight control and navigation data storage
Industrial automation controllers operating in extreme environmental conditions
Defense communication equipment signal processing and synchronization

Procurement Notes

Verify the specific suffix (Q2A) against official Texas Instruments documentation to confirm pinout, marking codes, and qualification standards. Ensure compatibility with existing board layouts due to the 20-CDIP package dimensions. Confirm that the TTL-compatible input requirements align with the system's logic voltage levels before integration.

Selection Notes

Select this component when an octal register with bus-compatible outputs is required for high-reliability applications. The AHCT series ensures compatibility with TTL-driven systems while offering CMOS power efficiency. Consider the extended temperature range and military qualification if the application involves harsh environments or critical safety functions.

Part Context

This part is a mil-aero version of the commercial SN54AHCT374. It shares the same logical functionality but undergoes stricter manufacturing controls and testing procedures defined by MIL-PRF-38534 or similar standards. The Q2A suffix denotes a specific package and marking code variant within the TI military product line.

Replacement Considerations

Direct replacements include other mil-aero versions of the SN54AHCT374 such as 5962-9853001QSA or 5962-9853001QRA, provided they match the required package and marking specifications. Verify that any substitute maintains the same TTL input compatibility and three-state output characteristics.
