74FCT162543CTPVCT

Buffers, Drivers, Receivers, Transceivers Overview

The CY74FCT162543CTPVCT is a 16-bit high-speed, low-power latched transceiver organized as two independent 8-bit D-type latched transceivers. It features balanced 24 mA output drivers with current limiting resistors to reduce system switching noise and ground bounce. The device supports partial-power-down mode via Ioff circuitry and operates within an industrial temperature range of -40°C to +85°C at VCC = 5V ± 10%. It is housed in a 56-lead SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Balanced 24 mA output drivers with integrated current limiting resistors for reduced undershoot and ground bounce
• Ioff circuitry enables partial-power-down mode by disabling outputs to prevent damaging current backflow
• Edge-rate control circuitry improves noise characteristics and reduces electromagnetic interference

Buffers, Drivers, Receivers, Transceivers Applications

• Driving transmission lines with minimal signal reflection
• Partial-power-down applications requiring safe power sequencing
• High-capacitance load driving in industrial systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CT indicates the commercial temperature grade variant within the FCT series. Confirm the PVCT suffix corresponds to the 56-lead SSOP tape and reel packaging format. Ensure the component matches the active status listed in the latest Texas Instruments package addendum before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when balanced drive strength and controlled edge rates are required to minimize ground bounce on transmission lines. The integrated current limiting eliminates the need for external terminating resistors. Choose this part over standard variants if partial-power-down protection and improved noise performance are critical design constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the CY74FCT162543T family of 16-bit latched transceivers manufactured by Texas Instruments. It shares functional similarities with the CY74FCT16543T but differs in output driver configuration, offering balanced 24 mA drivers instead of asymmetric 64 mA sink/32 mA source drivers. The family utilizes Fast CMOS technology for high-speed operation.
