MC74VHC595DTR2G

Shift Registers Overview

The MC74VHC595DTR2G is an onsemi CMOS shift register from the VHC logic series, housed in a TSSOP-16 surface-mount package. It functions as an 8-bit serial-to-serial/parallel converter with one circuit and nine output lines featuring three-state capability. The device operates within a supply voltage range of 2.5 V to 5 V and supports propagation delays of 16.5 ns and 10.2 ns. It is rated for industrial temperatures between -55°C and +125°C.

Shift Registers Feature Summary

• Serial data input converts to parallel outputs via internal shifting mechanism
• Three-state outputs allow direct connection to system buses without external drivers
• CMOS construction ensures low static power consumption across operating voltage range

Shift Registers Applications

• Data storage in digital communication interfaces
• Parallel expansion for microcontroller I/O ports
• LED display matrix scanning systems

Shift Registers Procurement Notes

Verify the complete part number including the DTR2G suffix to confirm the specific tape-and-reel packaging configuration. Ensure the procurement documentation references the correct VHC logic family specifications rather than generic HC or HCT variants. Confirm RoHS compliance status through official manufacturer certificates prior to integration into regulated assemblies.

Shift Registers Selection Notes

Select this component when designing circuits requiring eight-bit parallel output expansion from a single serial line. The VHC series offers faster switching speeds compared to standard HC logic while maintaining compatibility with 3.3 V and 5 V logic levels. The TSSOP-16 package provides a compact footprint suitable for high-density PCB layouts where space constraints limit larger packages.

Shift Registers Part Context

This integrated circuit belongs to the MC74VHC595 product family, which consists of high-speed silicon-gate CMOS devices. The family shares common architectural features including serial-in parallel-out functionality and three-state output control. These components are categorized under counter shift registers within the broader logic IC classification provided by the manufacturer.

Shift Registers Replacement Considerations

Cross-reference with other manufacturers' 8-bit shift registers such as the SN74VHC595 or NXP equivalents. Verify pinout compatibility and electrical characteristics match before substituting. Ensure the replacement part supports the required 3.3 V and 5 V operating voltages.
