8409501EA

Shift Registers Overview

The SN54HC165 (part number 8409501EA) is a parallel-load, 8-bit shift register manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports a clock frequency of up to 28 MHz. The device features a propagation delay of 38 ns and an operating current of 0.08 mA. It is housed in a 16-pin Ceramic Dual In-Line Package (CDIP), designated by the 'J' suffix, and is rated for an extended industrial temperature range from -55°C to 125°C.

Shift Registers Feature Summary

• Parallel data loading capability for simultaneous input acquisition
• Serial output shifting functionality with high-speed clock operation
• Robust ceramic packaging designed for harsh environmental conditions

Shift Registers Applications

• Military aerospace systems requiring wide temperature tolerance
• Industrial control interfaces needing reliable serial data expansion
• High-reliability computing hardware components

Shift Registers Procurement Notes

Verify the specific package type matches the required footprint, as this part utilizes a ceramic dual in-line package distinct from standard plastic variants. Confirm that the extended temperature rating aligns with the operational environment requirements. Ensure compatibility with existing logic families and voltage levels before integration into the design.

Shift Registers Selection Notes

Select this component when military-grade reliability and wide temperature operation are mandatory. The ceramic package offers superior durability compared to plastic alternatives. Consider the 2V minimum supply voltage for low-power applications. Verify pinout compatibility if replacing older logic families in legacy designs.

Shift Registers Part Context

This part belongs to the SN54HC series, which denotes high-speed CMOS logic designed for military specifications. The SN54 family typically features wider temperature ranges and stricter manufacturing controls than commercial SN74 counterparts. The HC logic family provides speed comparable to LS TTL but with lower power consumption.

Shift Registers Replacement Considerations

Direct substitutes include other SN54HC165 variants from Texas Instruments or equivalent parts from manufacturers like ON Semiconductor. Ensure any replacement maintains the CDIP package style and military temperature rating.
