MC74ACT323DWR2

Shift Registers Overview

The MC74ACT323DWR2 is an octal, bidirectional, three-state shift register manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and features low static power consumption with a maximum current of 8 uA. The device provides high drive capability with output currents of 32 mA at low level and -24 mA at high level. It exhibits a propagation delay of 10 ns at 5 V and functions reliably across an operating temperature range from -40°C to +85°C. Packaged in a 20-pin SOIC format, it supports surface mount installation.

Shift Registers Feature Summary

• Bidirectional data shifting capability for flexible parallel-in/parallel-out operations
• Three-state outputs enable direct connection to system buses without additional drivers
• CMOS construction ensures low static power dissipation during operation

Shift Registers Applications

• Parallel-to-serial or serial-to-parallel data conversion interfaces
• Bus buffering and temporary data storage in digital systems
• Shift register applications requiring bidirectional data flow control

Shift Registers Procurement Notes

Verify the complete part number including suffixes such as 'G' for RoHS compliance when ordering. Confirm package type and reel specifications match design requirements. Check humidity sensitivity handling instructions if moisture barrier packaging was compromised. Ensure supplier documentation matches the specific manufacturing lot for traceability purposes.

Shift Registers Selection Notes

Select this component for designs requiring bidirectional shifting with bus isolation capabilities. Compare propagation delays against system clock speeds to ensure timing margins are met. Evaluate package thermal characteristics for the intended enclosure environment. Verify that the 5V logic family compatibility aligns with existing input/output standards in the circuit architecture.

Shift Registers Part Context

This device belongs to the MC74ACT series of advanced CMOS logic components. It serves as a functional equivalent to standard octal shift registers but offers improved switching speeds and lower power consumption compared to older NMOS technologies. The ACT series is designed for high-density digital applications requiring reliable performance in consumer and industrial electronics.

Shift Registers Replacement Considerations

Check for MC74ACT323 variants with different suffixes for package or tape-and-reel options. Verify pinout compatibility before substituting with generic octal shift registers. Ensure replacement parts maintain the same bidirectional and three-state functionality.
