74HCT595PW,118

Shift Registers Overview

The Nexperia 74HCT595PW,118 is an 8-bit serial-in/serial or parallel-out shift register with output latches and 3-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features separate clocks for the shift and storage registers, a serial input (DS), and a serial output (Q7S) for cascading. It includes an asynchronous master reset (MR) input that clears the shift register on a LOW level. Data shifts on LOW-to-HIGH transitions of the SHCP input and transfers to the storage register on STCP transitions. Outputs assume a high-impedance state when the OE input is HIGH.

Shift Registers Feature Summary

• Provides 8-bit serial data conversion with independent shift and storage register clocks
• Features 3-state parallel outputs controlled by an active-low enable input
• Includes a direct clear function via an asynchronous master reset input
• Supports cascading through a dedicated serial data output pin

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register
• Register once, drag and drop applications

Shift Registers Selection Notes

Select this component for designs requiring TTL-compatible logic levels with CMOS performance. The HCT series ensures compatibility with standard TTL inputs while offering low power dissipation. Ensure the operating temperature range of -40 °C to +125 °C meets environmental requirements. Confirm that the TSSOP16 package dimensions align with the PCB footprint constraints.

Shift Registers Part Context

This part belongs to the 74HCT logic family, which bridges TTL and CMOS technologies. It is manufactured in a TSSOP16 plastic thin shrink small outline package (SOT403-1). The device is designed for general-purpose digital applications where reliable data shifting and latching are required under standard industrial temperature conditions.

Shift Registers Replacement Considerations

Check for equivalent parts from other manufacturers such as SN74HCT595PWR from Texas Instruments. Verify pinout compatibility and electrical specifications before substitution.
