MC74HC595ADT

Shift Registers Overview

The MC74HC595ADT is an 8-bit serial-input/serial or parallel-output shift register with latched 3-state outputs manufactured by onsemi. It integrates an 8-bit shift register and an 8-bit D-type latch, featuring independent clock inputs for both sections and an asynchronous reset for the shift register. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range from -55°C to +125°C. Propagation delays vary between 24 ns and 140 ns depending on voltage and load conditions.

Shift Registers Feature Summary

• Integrates an 8-bit shift register and an 8-bit D-type latch with independent clocking capabilities
• Provides three-state parallel outputs that directly interface with CMOS, NMOS, and TTL logic families
• Features an active-low asynchronous reset input that clears only the shift register portion
• Designed for direct interfacing with SPI serial data ports on CMOS microprocessors and microcontrollers

Shift Registers Applications

• Serial-to-parallel data conversion in embedded systems
• Expansion of I/O lines for microcontroller applications
• Display driver circuits requiring serial data input
• SPI interface peripheral expansion modules

Shift Registers Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-16 package configuration required for your design. Confirm RoHS compliance status through official manufacturer documentation as specifications may evolve. Ensure the component meets the thermal and electrical requirements for your intended operating environment before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with latched outputs and three-state capability is required. The HC series offers high noise immunity and low input current characteristics suitable for general-purpose digital logic applications. Consider the TSSOP-16 package constraints and verify voltage compatibility across the 2.0 V to 6.0 V operating range for your specific system architecture.

Shift Registers Part Context
