SNJ54BCT543JT

Overview

The SNJ54BCT543JT is an octal bus transceiver featuring back-to-back D-type latches for temporary data storage. It utilizes a state-of-the-art BiCMOS design to significantly reduce quiescent current (ICCZ). The device provides true outputs with 3-state capability and includes ESD protection exceeding 2000 V per MIL-STD-883C, Method 3015. It operates over the full military temperature range of -55 °C to 125 °C. The JT package is a 24-pin Ceramic Dual-In-Line (CDIP).

Feature Summary

• Back-to-back registers allow independent control of data flow direction.
• Separate latch-enable and output-enable inputs permit flexible operation.
• BiCMOS technology reduces power consumption.

Applications

• Military and defense applications requiring high reliability.
• Data storage in bidirectional bus systems.
• Temporary buffering of data flowing between ports.

Procurement Notes

Verify that the specific part number matches the required military qualification standards. Confirm the package type corresponds to the intended board layout. Ensure environmental specifications align with the operational requirements. Check for any specific ordering suffixes that may affect material or finish. Validate against the latest manufacturer documentation before procurement.

Selection Notes

Select this component when bidirectional data transfer with internal storage is necessary. The military temperature rating makes it suitable for harsh environments. Consider the separate enable inputs for complex timing requirements. Verify compatibility with system voltage levels and load conditions.

Part Context

This component belongs to the BCT logic family, which combines BiCMOS speed with CMOS low power consumption. The 'SNJ' prefix indicates a military-grade version from Texas Instruments. The '54' series denotes the military temperature range specification.

Replacement Considerations

Check for SNJ54BCT543 variants with different packages such as FK or W if pinout compatibility allows. Verify functional equivalence with other octal transceivers having latch capabilities.
