SN74HC595DBRG4

Shift Registers Overview

The SN74HC595DBRG4 is an 8-bit serial-in, serial/parallel-out shift register manufactured by Texas Instruments. It belongs to the SN74HC series of CMOS logic devices and is housed in a 16-pin SSOP package. The component features asynchronous reset functionality and operates within a supply voltage range of 2 V to 6 V. It supports a wide operating temperature range from -40°C to +85°C. Propagation delays are specified at 200 ns, 40 ns, and 34 ns depending on conditions. The device includes three-state outputs for bus-driven operations.

Shift Registers Feature Summary

• Serial-to-serial and serial-to-parallel data conversion capabilities
• Asynchronous direct clear input for immediate output resetting
• Three-state outputs allowing connection to shared data buses

Shift Registers Applications

• Industrial control systems requiring serial data expansion
• Consumer electronics utilizing low-power CMOS logic
• Automotive instrumentation with standard operating temperatures

Shift Registers Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with specific environmental standards. Confirm the SSOP-16 package type matches the target PCB footprint. Check RoHS documentation for current regulatory status. Ensure the supplier provides valid traceability records for quality assurance purposes.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with three-state outputs is required in a compact SSOP package. It is suitable for applications needing serial-to-parallel conversion within the HC logic family specifications. Consider the 2V to 6V operating range for compatibility with various system voltages.

Shift Registers Part Context

This device is part of the broader SN74HC595 family of 8-bit shift registers. It shares functional similarities with variants like SN74HC595DR but differs in packaging and specific manufacturing revisions. The DBR designation indicates the specific tape-and-reel packaging format for surface-mount assembly.
