74AHCT594DB,118

Shift Registers Overview

The 74AHCT594DB,118 is an 8-bit serial-in, parallel-out shift register with output latches manufactured by Nexperia USA Inc. It belongs to the 74AHCT logic family and operates within a supply voltage range of 4.5V to 5.5V. The device features push-pull outputs and is housed in a 16-SOIC package with a width of 3.90mm. It supports a wide operating temperature range from -40°C to +125°C and complies with RoHS3 standards.

Shift Registers Feature Summary

• Provides serial-to-parallel conversion functionality for data processing applications
• Features push-pull outputs for robust signal driving capabilities
• Compatible with standard CMOS logic families through AHCT input levels

Shift Registers Applications

• General-purpose digital logic circuits requiring data storage
• Industrial control systems operating in extended temperature environments
• Automotive electronics utilizing AEC-Q100 qualified variants

Shift Registers Procurement Notes

Verify the exact suffix against official Nexperia documentation to confirm package type and availability. Confirm that the specific ordering code matches the required 16-SOIC form factor. Check current production status as component availability may vary by region. Ensure compliance with relevant environmental regulations such as RoHS3 before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when a high-speed 8-bit shift register with latch capability is required. The AHCT series ensures compatibility with 5V CMOS logic inputs. Consider the 16-SOIC package for surface-mount assembly constraints. Evaluate thermal performance requirements given the wide operating temperature range specified for industrial and automotive use cases.

Shift Registers Part Context

This part is part of the broader 74AHCT594 product line, which includes variants like the 74AHC594D,118 and 74HCT594D,118. While sharing similar functional architectures, differences exist in supply voltage ranges and speed characteristics across the HC, HCT, and AHC sub-families. The DB suffix specifically denotes the SOIC package variant within the Nexperia portfolio.

Shift Registers Replacement Considerations

The 74HCT594D,118 serves as a verified alternative within the same manufacturer's lineup. Both parts share identical pinouts and core shifting functions. Verify voltage tolerance specifications if interfacing with non-standard logic levels. Cross-reference datasheets to ensure mechanical footprint compatibility during board redesigns.
