74LV595PW,118

Shift Registers Overview

The 74LV595PW,118 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 1.0 V to 3.6 V and supports temperatures from -40 °C to +125 °C. The device features separate clocks for the shift and storage registers, a serial input (DS), a serial output (Q7S) for cascading, and an asynchronous master reset (MR). It utilizes a TSSOP16 package (SOT403-1) and includes clamp diodes on inputs to allow interfacing with voltages exceeding VCC using current limiting resistors.

Shift Registers Feature Summary

• Provides 8-bit serial-to-parallel data conversion with independent shift and storage register clocks.
• Features 3-state parallel outputs controlled by an active LOW output enable (OE) input.
• Includes an asynchronous master reset (MR) input that clears the shift register when held LOW.
• Supports direct interface with TTL logic levels and offers ESD protection exceeding 2000 V (HBM).

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Verify the specific ordering suffix

Shift Registers Selection Notes

Select this component for designs requiring low-voltage operation down to 1.0 V with CMOS low power dissipation. Ensure the application environment stays within the specified temperature range of -40 °C to +125 °C. Consider the TSSOP16 package dimensions if PCB space is constrained. Verify that the system voltage does not exceed the maximum rating of 3.6 V to prevent damage.

Shift Registers Part Context

This part belongs to the 74LV series of logic ICs, designed for low-voltage applications. It is functionally similar to other 8-bit shift registers but optimized for the 1.0 V to 3.6 V supply range. The PW suffix indicates the TSSOP16 plastic thin shrink small outline package, distinguishing it from SO16 or SSOP variants in the same logical family.

Shift Registers Replacement Considerations

Check for pin-compatible alternatives such as the 74HC595 or 74LVC595 families, noting differences in supply voltage ranges and speed characteristics. Ensure any substitute maintains the required 3-state output functionality and package type.
