5496/BFA

Overview

The SNJ5496W is a parallel-in, parallel-out shift register belonging to the TTL/H/L series. It features a 5-bit architecture with right-shift direction capability and true outputs. The device is housed in a ceramic flatpack (CDFP16) package with 16 terminals. It operates within a temperature range of -55 °C to 125 °C and supports a supply voltage between 4.75 V and 5.5 V. The propagation delay is specified at 40 ns. The component meets MIL-PRF-38535 screening levels and includes functionality where clear followed by selective preset imitates load operations.

Feature Summary

• Parallel-in parallel-out data transfer capability
• Five-bit serial-to-parallel conversion with right-direction shifting
• Military-grade reliability with extended temperature operation
• Ceramic flatpack construction for high durability

Applications

• Military aerospace data storage systems
• High-reliability industrial control interfaces
• Defense communication equipment signal processing

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm exact screening level and testing requirements. Ensure the ceramic flatpack variant matches the required thermal and mechanical specifications for the target environment. Confirm that the TTL logic family compatibility aligns with existing system voltage and interface standards before integration.

Selection Notes

Select this component when a robust, five-bit shift register is required for harsh environments. The ceramic package offers superior protection compared to plastic alternatives. Verify that the 40 ns propagation delay meets the timing constraints of the application. Ensure the system design accommodates the specific power supply tolerances defined for the TTL/H/L series.

Part Context
