SN74AHC595BQBR

Shift Registers Overview

The SN74AHC595BQBR is an 8-bit serial-in, parallel-out shift register from the Texas Instruments AHC family. It incorporates a D-type storage register with 3-state outputs and operates within a supply voltage range of 2 V to 5.5 V. The device features separate clocks for the shift and storage registers, along with a direct overriding clear input. Packaged in a 16-pin WQFN (BQB) format measuring 3.5 mm by 2.5 mm, it supports operation across temperatures from -40°C to +125°C.

Shift Registers Feature Summary

• Provides 8-bit serial-to-parallel conversion with independent shift and storage clock inputs
• Features 3-state parallel outputs controlled by an output-enable pin
• Includes a direct overriding clear input for immediate data reset
• Offers high electrostatic discharge protection exceeding JESD standards

Shift Registers Applications

• Network Switches
• Power Infrastructures
• LED Displays
• Servers

Shift Registers Procurement Notes

Verify the specific BQB package variant against the latest TI orderable information to ensure compatibility with design constraints. Confirm that the RoHS status and lead finish meet project requirements. Cross-reference the active production status with current availability channels to align with manufacturing schedules.

Shift Registers Selection Notes

Select this component when a low-drive CMOS solution is required to minimize output ringing on bus interfaces. Ensure the application utilizes the wide operating voltage range suitable for systems between 2 V and 5.5 V. Consider the thermal characteristics of the WQFN package if high ambient temperatures are expected.
