SN74HC595ADB

Shift Registers Overview

The SN74HC595ADB is an 8-bit serial-in, parallel-out shift register from the Texas Instruments 74HC logic family. It features a serial input and eight parallel outputs with three-state capability. The device operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -40°C to +85°C. It utilizes CMOS technology and includes a direct clear function for the shift register. The component is housed in a 16-SSOP package.

Shift Registers Feature Summary

• Converts serial data input into parallel output across eight bits
• Provides three-state outputs for bus-driven applications
• Includes direct clear functionality for the shift register stage

Shift Registers Applications

• Microcontroller I/O expansion
• Serial-to-parallel data conversion interfaces
• LED display driver circuits

Shift Registers Procurement Notes

Verify the specific suffix 'ADB' against official Texas Instruments documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with system voltage levels and thermal requirements before integration. Cross-reference ordering information with authorized distributors to confirm current availability and manufacturing status.

Shift Registers Selection Notes

Select this component when a compact 16-pin SSOP form factor is required for space-constrained designs. It is suitable for applications needing low power consumption and high noise immunity typical of HC logic families. Consider alternative packages like TSSOP or SOIC if different footprint constraints apply.

Shift Registers Part Context

This part belongs to the SN74HC595 series of 8-bit shift registers. The 'HC' designation indicates High-speed CMOS technology, offering faster switching speeds compared to standard 74C series devices while maintaining low power dissipation. The series is widely used in digital logic systems requiring data storage and transfer capabilities.

Shift Registers FAQ

What is the function of the SRCLR pin?

The SRCLR pin provides a direct clear function for the shift register. When driven low, it resets all shift register flip-flops to zero, regardless of clock or data inputs.

How does the three-state output benefit the design?

The three-state outputs allow the device to be connected to a common bus without interfering with other devices. When the Output Enable (OE) pin is high, the outputs enter a high-impedance state, effectively disconnecting them from the circuit.
