CD74ACT164E

Shift Registers Overview

The CD74ACT164E is an 8-bit serial-in, parallel-out shift register from the Texas Instruments 74ACT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features push-pull outputs. The device is housed in a 14-pin PDIP package designed for through-hole mounting. It supports an operating temperature range from -55 °C to +125 °C and utilizes positive edge-triggered clocking with asynchronous reset functionality.

Shift Registers Feature Summary

• Serial-to-parallel data conversion capability
• Push-pull output structure
• Asynchronous reset mechanism

Shift Registers Applications

• Data storage applications
• Parallel-to-serial conversion circuits
• Timing delay generation

Shift Registers Procurement Notes

Verify the specific package variant against design requirements, as surface-mount options like the CD74ACT164M96 exist. Confirm that the 4.5 V to 5.5 V supply voltage range aligns with the system power rails. Ensure the through-hole PDIP footprint matches the PCB layout constraints.

Shift Registers Selection Notes

Select this component when 8-bit serial shifting with parallel output is required in industrial environments. The ACT series provides CMOS compatibility with TTL input levels. Consider the PDIP package only if through-hole assembly is mandated by the manufacturing process or mechanical stability needs.

Shift Registers Part Context

This part belongs to the 74ACT family, which bridges AC speed with HC/TTL compatibility. It serves as a fundamental building block for digital systems requiring temporary data storage or waveform generation. The device is distinct from counters or latches due to its specific shift register architecture.
