SNJ54HC165J

Overview

The SNJ54HC165J is an 8-bit parallel-load shift register from the Texas Instruments 54HC series. It features a serial output and accepts eight parallel data inputs. The device operates within a temperature range of -55°C to 125°C. Key electrical specifications include an output drive capability of 5.2 mA (IOL/IOH) and CMOS output type. It is housed in a 16-lead Ceramic Dual In-Line Package (CDIP).

Feature Summary

• Supports parallel data loading for rapid state capture.
• Provides serial output for cascading or sequential processing.
• Designed for high-temperature military environments.

Applications

• Military-grade digital logic circuits
• High-reliability data acquisition systems
• Industrial control interfaces

Procurement Notes

Verify the 'J' suffix indicates the ceramic package variant, which differs from plastic equivalents. Confirm RoHS status as non-compliant due to lead content typical of this package style. Ensure the supplier provides official Texas Instruments documentation to validate the military grade specification and operating temperature range.

Selection Notes

Select this component when military-grade reliability and wide temperature operation are required. The ceramic package offers superior environmental resistance compared to plastic variants. Verify that the 54HC series voltage levels match the system requirements before integration.

Part Context

This part belongs to the SN54HC165 family of 8-bit shift registers. The 'SNJ' prefix denotes the specific manufacturer code and ceramic dual in-line package configuration. It is distinct from commercial grade parts by its extended temperature rating and robust packaging suitable for harsh conditions.

Replacement Considerations

Substitutes must maintain the 54HC series logic compatibility and CDIP package form factor. Verify that alternative sources offer the same -55°C to 125°C operating range. Ensure pinout compatibility with the original SN54HC165J specification.
