74LV595DB,112

Shift Registers Overview

The Nexperia 74LV595DB,112 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. It operates within a supply voltage range of 1.0 V to 3.6 V and features separate clocks for the shift and storage registers. The device includes a serial input (DS), a serial output (Q7S) for cascading, and an asynchronous master reset (MR) input. Data shifts on LOW-to-HIGH transitions of the SHCP input and transfers to the storage register on STCP transitions. Outputs are enabled when OE is LOW; otherwise, they enter a high-impedance state.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion capabilities with independent shift and storage register clocks.
• Features 3-state outputs controlled by an active LOW enable input for bus driver applications.
• Includes an asynchronous master reset input to clear the shift register independently of clock signals.
• Supports direct interface with TTL levels and offers ESD protection exceeding 2000 V HBM.

Shift Registers Applications

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

Shift Registers Selection Notes

Select this component for designs requiring low-voltage operation down to 1.0 V. Ensure the application utilizes the SO16 package variant compatible with the DB suffix. Confirm that the system timing requirements align with the specified propagation delays and maximum frequencies across the intended temperature range.

Shift Registers Part Context

This part belongs to the 74LV595 family of 8-bit shift registers manufactured by Nexperia. It is pin and function compatible with 74HC/HCT595 devices but optimized for lower voltage applications. The product data sheet indicates that previous SSOP16 variants have been removed from the current specification.
