SN74HC595NSR-P

Shift Registers Overview

The SN74HC595NSR-P is an 8-bit serial-in, parallel-out shift register with a D-type storage register and 3-state outputs. It operates within a voltage range of 2 V to 6 V and supports temperatures from -40°C to +85°C. The device features a direct clear input, separate clocks for shift and storage registers, and cascading serial outputs. Propagation delays are specified at 200 ns, 40 ns, and 34 ns depending on conditions.

Shift Registers Feature Summary

• Provides 8-bit serial-to-parallel conversion with independent clocking for shift and storage registers
• Features high-current 3-state outputs capable of driving multiple LSTTL loads
• Includes a direct overriding clear function for the shift register

Shift Registers Applications

• Network switches
• Power infrastructure
• LED displays
• Servers

Shift Registers Procurement Notes

Verify the exact suffix 'P' against the manufacturer's official orderable addendum, as standard datasheets list 'SN74HC595NSR'. Confirm package dimensions and thermal resistance values match the specific variant requirements. Ensure compatibility with the intended operating temperature range and supply voltage specifications before integration.

Shift Registers Selection Notes

Select this component for applications requiring low power consumption and wide voltage operation. The HC logic family offers balanced drive capabilities suitable for bus interfaces where output ringing must be minimized. Consider the separate clock inputs for precise timing control between shifting data and latching outputs.

Shift Registers Part Context

This device belongs to the Texas Instruments SNx4HC595 family of CMOS logic integrated circuits. It is designed for general-purpose digital applications requiring serial data expansion. The NS package denotes a small-outline package variant optimized for surface-mount assembly processes.

Shift Registers FAQ

How does the device handle unused inputs?

All unused inputs must be connected to either VCC or GND to prevent undefined operational states caused by floating voltages.

What is the function of the OE pin?

When the Output Enable (OE) input is high, the outputs QA through QH enter a high-impedance state, effectively disabling them.
