SN74AHCT595NE4

Shift Registers Overview

The SN74AHCT595NE4 is an 8-bit serial-in, parallel-out shift register with a storage register and 3-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40°C to 125°C. The device features TTL-voltage compatible inputs and includes a direct clear input for the shift register. Both the shift register clock (SRCLK) and storage register clock (RCLK) are positive-edge triggered.

Shift Registers Feature Summary

• TTL-voltage compatible inputs
• Direct overriding clear for the shift register
• Positive-edge triggered separate clocks for shift and storage registers

Shift Registers Applications

• Network switches
• Power infrastructures
• LED displays

Shift Registers Procurement Notes

Verify the component against official Texas Instruments documentation to confirm specifications and authenticity. Ensure that the ordering suffix 'E4' corresponds to the required lead-free packaging and RoHS compliance status as defined in the manufacturer's current product information. Cross-reference the datasheet revision history for any updates to electrical characteristics or thermal data prior to finalizing procurement.

Shift Registers Selection Notes

Select this component when a CMOS shift register requires compatibility with TTL logic levels. The device is suitable for applications needing separate control over shifting and latching operations via distinct clock inputs. Consider the wide operating temperature range and high ESD protection ratings for robust system designs requiring reliable data transfer in industrial environments.

Shift Registers Part Context

This part belongs to the SNx4AHCT595 family of 8-bit shift registers manufactured by Texas Instruments. The 'HCT' designation indicates High-speed CMOS technology with TTL-compatible input thresholds. The 'NE4' suffix specifies the PDIP-16 package type and lead-free manufacturing process compliant with environmental directives.
