SN74LV164APW

Shift Registers Overview

The SN74LV164APW is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It belongs to the LV (Low-Voltage CMOS) logic family and operates within a supply voltage range of 2 V to 5.5 V. The device features asynchronous clear functionality and accepts data on two serial input pins (A and B), which are internally ANDed. It utilizes a TSSOP-14 surface-mount package. Propagation delays vary between 11 ns and 21.1 ns depending on conditions. The component supports mixed-mode operation, allowing interfacing with different voltage domains, and includes latch-up performance exceeding 100 mA per JESD 78 Class II specifications.

Shift Registers Feature Summary

• Serial-to-parallel data conversion capability for expanding parallel outputs from limited serial lines
• Asynchronous clear function to reset all flip-flops independently of clock signals
• Dual serial inputs (A and B) that are logically combined to control data entry
• Support for mixed-mode voltage operation across the specified supply range

Shift Registers Applications

• General-purpose serial-to-parallel data expansion in digital systems
• Driving LED displays or indicator arrays requiring sequential data loading
• Interface circuits connecting microcontrollers with limited I/O to peripheral devices

Shift Registers Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-14 package variant required for your design. Confirm the operating temperature range meets your environmental specifications. Check current production status as availability may vary. Ensure voltage levels at inputs and outputs are compatible with the 2 V to 5.5 V operating range to prevent damage or malfunction.

Shift Registers Selection Notes

Select this component when an 8-bit parallel output is needed from a serial source within the LV logic family. Consider the TSSOP-14 package constraints for PCB layout. Evaluate propagation delay requirements against system timing budgets. Verify that the asynchronous clear feature aligns with system reset strategies. Compare power consumption characteristics if low-power operation is critical.

Shift Registers Part Context

This part is part of the SN74LV164A series of 8-bit shift registers. It shares functional similarities with other members of the LV family but differs in packaging and specific electrical characteristics. The 'A' designation typically indicates improved specifications over earlier versions. It serves as a standard solution for basic serial data expansion tasks in consumer and industrial electronics.
