SN74LV164APWT

Shift Registers Overview

The SN74LV164APWT is an 8-bit serial-in, parallel-out shift register from Texas Instruments' LV logic family. It operates within a supply voltage range of 2 V to 5.5 V and features a TSSOP-14 package. The device supports mixed-mode operation, allowing inputs to interface with voltages up to 5.5 V while the core operates at lower levels. Propagation delays are specified at 21.1 ns, 16.3 ns, and 11 ns depending on conditions. It functions as a CMOS circuit with asynchronous reset capabilities.

Shift Registers Feature Summary

• Serial-to-parallel data conversion for expanding parallel outputs from limited serial lines
• Asynchronous reset functionality to clear all storage elements immediately
• Mixed-mode voltage support enabling 5.5 V tolerant inputs for system flexibility

Shift Registers Applications

• General-purpose serial-to-parallel expansion in embedded systems
• Data acquisition interfaces requiring parallel output generation
• Control logic circuits utilizing low-voltage CMOS technology

Shift Registers Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeits. Confirm package integrity upon receipt, as TSSOP-14 pins are susceptible to damage during handling. Ensure compatibility with existing board designs regarding pinout and thermal requirements before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when low power consumption and wide voltage operation are required. The LV series offers better performance than standard TTL at lower voltages. Consider the TSSOP-14 package size constraints and ensure adequate PCB space for surface mount assembly processes.

Shift Registers Part Context

This part belongs to the SN74LV164A family of shift registers designed for low-voltage applications. It provides a cost-effective solution for converting serial data streams into parallel formats. The LV technology ensures compatibility with modern low-power digital systems while maintaining robust noise immunity.

Shift Registers Replacement Considerations

SN74LV164ADGVR serves as a direct functional substitute with identical electrical characteristics but utilizes a TVSOP-14 package instead of TSSOP-14. Verify pin compatibility and thermal dissipation requirements when substituting packages.
