Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging when sourcing this component. Confirm that the SOIC-14 package matches the required footprint and pin spacing for the target PCB layout. Ensure the procurement documentation aligns with the manufacturer's specifications for the 74ACT series to guarantee correct electrical characteristics and performance levels.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring buffered signals with high drive strength and controlled output impedance. The 3-STATE feature allows multiple devices to share a common bus without interference. Consider the ACT series for applications needing faster propagation delays compared to standard logic while maintaining TTL input compatibility.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC/ACT logic family, which offers higher speed and lower power consumption than legacy 74LS series devices. The 74ACT variant specifically bridges the gap between AC speed and TTL voltage compatibility. It is widely used in digital systems where signal integrity and bus management are critical requirements.
