74VHC595SJX

Shift Registers Overview

The Fairchild Semiconductor 74VHC595SJX is an advanced high-speed CMOS 8-bit shift register with output latches, fabricated using silicon gate CMOS technology. It operates within a voltage range of 2.0 V to 5.5 V and features low power dissipation. The device includes serial input and standard serial output for cascading, along with asynchronous reset functionality for all eight stages. It utilizes separate positive-edge-triggered clocks for the shift and storage registers. The component is housed in a 16-lead Small Outline Package (SOIC) with a 3.90 mm width.

Shift Registers Feature Summary

• Advanced high-speed CMOS technology providing operation similar to equivalent Bipolar Schottky TTL while maintaining low power consumption.
• Integrated power-down protection on all inputs to prevent excessive current draw during standby states.
• Separate clock inputs allow independent control of data shifting and storage latching operations.

Shift Registers Applications

• Remote control systems requiring data holding capabilities
• Serial-to-parallel data conversion interfaces
• Parallel output expansion for microcontroller I/O ports

Shift Registers Procurement Notes

Verify the specific suffix SJX against official datasheets to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for SOIC-16 packages. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Shift Registers Selection Notes

Select this component when high-speed shifting is required alongside low static power consumption. The VHC series offers faster propagation delays compared to standard HC logic. Verify that the operating voltage aligns with the system's 2.0 V to 5.5 V supply range and that the SOIC-16 package fits the design constraints.

Shift Registers Part Context

This part belongs to the 74VHC family of high-speed CMOS logic devices. It is functionally compatible with the 74HC595 but provides improved switching speeds. The device serves as a fundamental building block for digital data handling, enabling efficient management of serial data streams into parallel formats for display or processing applications.

Shift Registers Replacement Considerations

Direct pin-compatible alternatives include the 74HC595 for standard speed applications and the 74AHC595 for enhanced performance. Verify electrical characteristics such as propagation delay and drive strength when substituting to ensure circuit timing requirements are met.
