SN74HC164PW

Shift Registers Overview

The SN74HC164PW is an 8-bit parallel-out serial shift register manufactured by Texas Instruments in a 14-pin TSSOP package. It operates on a supply voltage ranging from 2 V to 6 V and supports an operating temperature range of -40°C to 125°C. The device features AND-gated serial inputs (A and B) and an asynchronous clear (CLR) input. Outputs are capable of driving up to 10 LSTTL loads with ±4-mA drive at 5 V. Typical propagation delay is 20 ns, with maximum clock frequencies reaching 36 MHz at 6 V.

Shift Registers Feature Summary

• AND-gated serial inputs allow complete control over incoming data entry
• Asynchronous direct clear resets all registers immediately upon low signal
• Push-pull outputs provide strong drive capability for multiple loads

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the 14-pin Thin Shrink Small Outline Package (TSSOP). Confirm the required temperature grade matches the standard commercial/industrial rating (-40°C to 125°C). Ensure the design accommodates the specified power supply voltage limits and ESD protection requirements during handling.

Shift Registers Selection Notes

Select this component when a serial-to-parallel conversion function is required within a CMOS logic family. The wide voltage range suits various digital systems. Verify that the 14-pin TSSOP footprint fits the PCB layout constraints. Consider the propagation delay specifications against the system clock speed requirements.

Shift Registers Part Context

This part belongs to the SNx4HC164 family of 8-bit shift registers. It is pin-compatible with other variants like the SOIC (SN74HC164D) and PDIP (SN74HC164N) packages. The HC series denotes high-speed CMOS technology, offering faster operation than standard 74C series devices while maintaining low power consumption.

Shift Registers Replacement Considerations

Check for equivalent parts from other manufacturers such as MC74HC164ADR2G or MM74HC164MTCX. Verify package compatibility and electrical characteristics before substitution.
