74HCT595D/AUJ

Shift Registers Overview

The 74HCT595D/AUJ is an 8-bit serial-in, serial or parallel-out shift register with output latches and 3-state outputs. Manufactured by NXP USA Inc., it belongs to the HCT logic family, ensuring compatibility with Low-power Schottky TTL (LSTTL). The device integrates a separate shift register and storage register, allowing independent clocking for efficient data handling. It operates within a supply voltage range of 4.5V to 5.5V and supports a typical shift-out frequency of 100 MHz. The component is housed in a TSSOP-16 package and is specified for operation across extended temperature ranges.

Shift Registers Feature Summary

• Provides 8-bit serial input capability for flexible data integration
• Features storage registers with 3-state outputs for bus sharing
• Includes direct clear function for the shift register
• Offers ESD protection exceeding standard thresholds

Shift Registers Applications

• Serial-to-parallel data conversion systems
• Remote control holding registers
• Industrial communication interfaces requiring latch functionality

Shift Registers Procurement Notes

Verify the specific suffix 'AUJ' against official NXP documentation to confirm the exact package type and tape/reel specifications. Ensure the ordering part number matches the required automotive or industrial qualification standards if applicable. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and recommended operating conditions before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when TTL-compatible logic levels are required alongside high-speed shifting capabilities. The HCT series ensures seamless interface with legacy LSTTL systems while providing CMOS efficiency. Consider the TSSOP-16 package for space-constrained surface-mount designs. Verify that the 3-state output requirement aligns with the system's bus architecture needs.

Shift Registers Part Context

This component is part of the widely adopted 74HCT595 family, designed for general-purpose digital logic applications. It serves as a fundamental building block for expanding I/O ports in microcontroller-based systems. The device replaces older discrete logic solutions by integrating shift and storage functions into a single integrated circuit, simplifying board layout and reducing component count.

Shift Registers Replacement Considerations

Compatible alternatives include the 74HC595D for CMOS-level applications and the 74HCT595PW from Nexperia. Verify pin compatibility and electrical characteristics such as propagation delay and supply voltage tolerance before substitution.
