SN74HC594DWRG4

Shift Registers Overview

The SN74HC594DWRG4 is an 8-bit serial-in, parallel-out shift register with an output storage register. It operates within a supply voltage range of 2 V to 6 V and features high-current outputs capable of driving up to 15 LSTTL loads. The device includes independent direct overriding clear inputs for both the shift and storage registers, as well as separate positive edge-triggered clocks for each stage. A serial (QH') output facilitates cascading multiple devices.

Shift Registers Feature Summary

• Wide operating voltage range from 2 V to 6 V
• High-current outputs drive up to 15 LSTTL loads
• Independent direct overriding clears on shift and storage registers
• Separate clocks for shift and storage registers

Shift Registers Applications

• Pro Audio Mixer
• Elevators and Escalators
• Human Machine Interface: Industrial Monitor
• Entertainment Systems
• Grid Infrastructure: Grid Control
• Access Control and Security: DVR and DVS

Shift Registers Procurement Notes

Verify the RoHS compliance status and lead finish details against the latest Texas Instruments Package Option Addendum. Confirm that the SOIC DW package dimensions match your PCB footprint requirements. Ensure input pins are not left floating during operation to maintain stable logic states. Check the moisture sensitivity level rating before soldering to prevent damage during assembly.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel conversion is required with registered outputs. The wide voltage range supports systems operating between 2 V and 6 V. High-current outputs make it suitable for driving medium loads directly. Use separate clock inputs if independent control of shifting and latching is necessary. Consider the SOIC DW package for surface-mount applications requiring specific board space constraints.

Shift Registers Part Context

This part belongs to the SNx4HC594 family of 8-bit shift registers with output registers manufactured by Texas Instruments. It utilizes CMOS technology for low power consumption. The device is designed for general-purpose digital logic applications where data serialization and parallel output are needed. It is distinct from other logic families by its specific combination of shift and storage capabilities with independent clearing functions.
