PI74FCT245ATS

Buffers, Drivers, Receivers, Transceivers Overview

The PI74FCT245ATS is an octal bidirectional bus transceiver from the FCT logic series, manufactured by Diodes Incorporated. It operates on a single 5V supply (4.75V to 5.25V) and features TTL-compatible input and output levels. The device provides three-state outputs with a propagation delay of 7 ns. It supports low ground bounce performance and includes hysteresis on all inputs for noise immunity. The component is housed in a 20-pin SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ATS' against the official datasheet to confirm package type and material specifications. Confirm end-of-life status and lead times through authorized distributors. Ensure compatibility with existing PCB footprints for the 20-pin SOIC package. Check for RoHS compliance requirements if applicable to the target assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed octal data transfer is required with TTL level compatibility. It is suitable for applications needing low power consumption compared to bipolar equivalents. Consider the 7 ns propagation delay and drive capabilities for signal integrity. Verify that the 5V operating voltage aligns with the system design constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Pericom FCT series of fast CMOS logic circuits, now produced under Diodes Incorporated. The FCT series offers higher speed and lower power than traditional bipolar FAST series devices. The PI74FCT245 variant specifically provides non-inverting octal bus transceiver functionality with direction control.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for pin-compatible alternatives within the same FCT family or other manufacturers offering equivalent 8-bit bus transceivers with 5V operation and SOIC-20 packaging. Verify electrical parameters such as propagation delay and output current drive before substitution.
