SN74HC164DRG4

Shift Registers Overview

The SN74HC164DRG4 is an 8-bit parallel-out serial shift register manufactured by Texas Instruments in a 14-pin SOIC package. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature from -40°C to 125°C. The device features AND-gated serial inputs (A and B) and an asynchronous clear (CLR) input. Typical propagation delay is 20 ns, with maximum clock frequencies reaching 36 MHz at 6 V. Output drive capability is ±4 mA at 5 V.

Shift Registers Feature Summary

• AND-gated serial inputs allow complete control over incoming data entry
• Asynchronous direct clear function resets all registers immediately
• Fully buffered clock and serial inputs ensure signal integrity
• Low power consumption with maximum ICC of 80 µA

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the active production status and RoHS compliance for the SN74HC164DRG4 variant. Confirm the specific lead finish (NIPDAU) and moisture sensitivity level (Level-1) requirements against your assembly process specifications. Ensure the ordering suffix matches the desired packaging configuration.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel conversion is required with independent serial input gating. The wide voltage range and high-speed operation make it suitable for general-purpose logic applications. Verify that the load capacitance does not exceed 50 pF to maintain specified switching characteristics.

Shift Registers Part Context

This part belongs to the SNx4HC164 family of 8-bit shift registers. It shares functional compatibility with other variants like SN74HC164D and SN74HC164DT, differing primarily in packaging and manufacturing revisions. The G4 suffix indicates a specific generation of lead-free processing and environmental compliance.

Shift Registers Replacement Considerations

SN74HC164DR is a compatible alternative within the same product line.
