PI74FCT543ATS

Buffers, Drivers, Receivers, Transceivers Overview

The PI74FCT543ATS is an 8-bit wide non-inverting latched transceiver manufactured by Diodes Incorporated using advanced 0.8 micron CMOS technology. It features two sets of eight D-type latches with separate input and output controls for each set, enabling bidirectional data flow between A and B ports. The device includes a built-in 25 ohm series resistor on all outputs to reduce noise from reflections. It operates within an industrial temperature range of -40°C to +85°C and supports TTL input and output levels.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'ATS' against official datasheets to confirm package type and material specifications. Confirm RoHS compliance status as historical documentation may indicate lead-based variants. Ensure the component meets current environmental regulations before integration into final assemblies.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed bidirectional data transfer with storage capability is required. The integrated latching mechanism allows for precise control over data flow timing. Consider the 25 ohm series resistance for applications requiring reduced signal reflection without additional external components.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the PI74FCT series of fast CMOS logic circuits produced by Pericom Semiconductor Corporation, now part of Diodes Incorporated. The series is known for achieving industry-leading speed grades while maintaining lower power consumption compared to bipolar FAST Series equivalents. The PI74FCT543T/544T family represents latched transceivers designed for robust digital system interfacing.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The PI74FCT543T/544T is pin compatible with bipolar FAST Series devices. Verify functional equivalence if substituting with other 8-bit latched transceivers in the same logic family.
