Shift Registers Overview

The SN54HC164 is an 8-bit parallel-out serial shift register featuring AND-gated serial inputs and an asynchronous clear function. It operates within a supply voltage range of 2 V to 6 V, with outputs capable of driving up to 10 LSTTL loads. The device exhibits low power consumption, with a maximum ICC of 80 μA, and typically achieves a propagation delay (tpd) of 20 ns. Output drive capability reaches ±4 mA at 5 V, supported by a maximum input current of 1 μA.

Shift Registers Feature Summary

• AND-gated serial inputs allow complete control over incoming data entry
• Asynchronous direct clear input resets all registers immediately
• Fully buffered clock and serial inputs ensure signal integrity

Shift Registers Applications

• Programmable Logic Controllers
• Appliances
• Video Display Systems
• Output Expander

Shift Registers Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm the exact package type, such as CDIP or CFP, and the corresponding temperature rating. Ensure compliance with MIL-PRF-38535 requirements if specified for military-grade applications. Confirm RoHS status and lead finish details directly from the manufacturer's documentation before procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with dual gated serial inputs is required. Verify that the operating voltage falls between 2 V and 6 V and that the temperature range meets system needs. Consider the package availability, such as CDIP or CFP, based on board layout constraints and mounting style requirements.

Shift Registers Part Context

This part belongs to the SNx4HC164 family of 8-bit shift registers manufactured by Texas Instruments. It is designed for high-speed digital logic applications requiring serial-to-parallel conversion. The device supports both commercial and military temperature ranges depending on the specific variant selected.

Shift Registers FAQ

How do the AND-gated serial inputs function?

Data enters the shift register only when both serial inputs A and B are high. A low signal at either input inhibits new data entry and resets the first flip-flop to the low level upon the next clock pulse.

What triggers the data shift in the register?

Clocking occurs on the low-to-high-level transition of the CLK pin. Data stored in the first flip-flop propagates to the subsequent registers with each positive edge trigger.
