74HC595DR2G

Shift Registers Overview

The MC74HC595ADR2G is an 8-bit serial-input/serial or parallel-output shift register with latched 3-state outputs. It consists of an 8-bit shift register and an 8-bit D-type latch. The device operates within a voltage range of 2.0 to 6.0 V and supports an operating temperature from -55°C to +125°C. Propagation delays vary between 24 ns and 140 ns depending on supply voltage. Maximum clock frequencies range from 4.0 MHz to 35 MHz.

Shift Registers Feature Summary

• Provides independent clocks for the shift register and storage latch, allowing stable parallel outputs during shifting operations.
• Features asynchronous active-low reset input that clears only the shift register without affecting the latch contents.
• Includes three-state parallel outputs controlled by an active-low output enable signal for direct bus interfacing.

Shift Registers Applications

• Serial-to-parallel data conversion
• Parallel-to-serial data conversion
• SPI serial data port interfacing

Shift Registers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and lead-free status. Ensure compatibility with required operating voltage ranges and temperature specifications before integration. Confirm RoHS compliance requirements match project standards.

Shift Registers Selection Notes

Select this component when high-speed CMOS performance with low power dissipation is required. Consider the independent clock inputs for applications needing simultaneous shifting and latching. Evaluate propagation delay specifications relative to system timing constraints.

Shift Registers Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It is functionally compatible with standard 74HC595 devices but may offer improvements in propagation delays and noise immunity. The device is manufactured using silicon gate CMOS technology.

Shift Registers Replacement Considerations

Check datasheets for SN74HC595DR and MC74HCT595ADR2G to verify pinout and electrical parameter compatibility. Ensure substitute parts meet the same voltage and temperature requirements.
