SN74HC595NE4

Shift Registers Overview

The SN74HC595NE4 is an 8-bit serial-in, serial/parallel-out shift register manufactured by Texas Instruments. It belongs to the SNx4HC595 family and utilizes CMOS logic technology. The device features a wide operating voltage range from 2 V to 6 V and operates within a temperature range of -40°C to +85°C. It is housed in a 16-pin PDIP package designed for through-hole mounting. Key electrical characteristics include a propagation delay of 34 ns at 5 V, with maximum output currents supporting LSTTL loads.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion capabilities for expanding microcontroller I/O lines.
• Features tri-state outputs that enter a high-impedance state when the output enable pin is asserted high.
• Includes a direct clear input to reset the shift register independently of clock signals.

Shift Registers Applications

• Microcontroller port expansion for controlling multiple peripheral devices.
• LED display matrix scanning and driver circuits.
• Industrial control systems requiring reliable serial data shifting.

Shift Registers Procurement Notes

Verify the specific ordering suffix NE4 corresponds to the lead-free PDIP-16 package configuration. Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure the procurement channel provides traceable component history to guarantee authenticity and prevent counterfeit risks during assembly.

Shift Registers Selection Notes

Select this component when a through-hole PDIP-16 form factor is required for prototyping or legacy board designs. Compare against surface-mount variants like SN74HC595NSR if PCB space constraints dictate SMD packaging. Verify that the 2 V to 6 V supply range aligns with the target system's power architecture.

Shift Registers Part Context

This part is a member of the Texas Instruments SN74HC595 series, which standardizes 8-bit shift registers with tri-state outputs across various packages. The NE4 suffix specifically denotes the lead-free PDIP-16 variant, distinguishing it from SOIC or TSSOP versions while maintaining identical internal circuitry and functional specifications.

Shift Registers Replacement Considerations

Direct substitutes include SN74HC595N (standard PDIP-16) and SN74HC595DR (SOIC-16). Cross-package replacements require verifying pin compatibility and thermal management requirements.
