74LV165PW,112

Shift Registers Overview

The 74LV165PW,112 is an 8-bit parallel-in/serial-out shift register manufactured by Nexperia. It features a serial data input (DS), eight parallel data inputs (D0 to D7), and two complementary serial outputs (Q7 and Q7). The device operates with a wide supply voltage range from 1.0 V to 5.5 V and includes clamp diodes on inputs for overvoltage interfacing. Data loads asynchronously when the parallel load input (PL) is LOW. Shifting occurs on LOW-to-HIGH clock transitions when the clock enable (CE) is LOW.

Shift Registers Feature Summary

• Supports synchronous parallel-to-serial conversion and serial input expansion
• Provides direct interface compatibility with TTL logic levels within the 2.7 V to 3.6 V range
• Includes input clamp diodes allowing current limiting resistors for voltages exceeding VCC
• Complies with JEDEC standards for various low-voltage applications

Shift Registers Applications

• Synchronous parallel-to-serial data conversion
• Serial input expansion in digital systems
• Interfacing with TTL level logic circuits

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Confirm current production status as product lifecycles may change. Ensure design compliance with absolute maximum ratings to prevent permanent damage. Cross-reference pin assignments with the functional diagram before integration.

Shift Registers Selection Notes

Select this component for designs requiring 8-bit parallel data acquisition with serial output capability. Consider the 1.0 V to 5.5 V operating range for flexible power supply options. Verify that the TSSOP16 package fits the PCB layout constraints. Check propagation delay specifications against system timing requirements at the target supply voltage.

Shift Registers Part Context

This part belongs to the 74LV family of low-voltage CMOS logic devices. The PW suffix indicates a TSSOP16 plastic thin shrink small outline package. It serves as a standard shift register solution for converting parallel data streams into serial formats for transmission or processing.

Shift Registers Replacement Considerations

The 74LV165D is a compatible alternative using an SO16 package.
