CY74FCT16652ATPVCT

Overview

The CY74FCT16652ATPVCT is a 16-bit registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input and output levels. The device provides three-state outputs with a low-level output current of 64 mA and a high-level output current of -32 mA. It exhibits a propagation delay of 6.3 ns and is housed in an SSOP-56 package. The component supports surface-mount installation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates 16-bit data latching capability for synchronized bus operations
• Provides bidirectional data transfer between two buses
• Features three-state outputs to isolate the bus when disabled

Applications

• High-speed data acquisition systems requiring buffered storage
• Clock domain crossing interfaces in digital logic circuits
• Memory buffer applications in computing architectures

Procurement Notes

Verify the specific suffix 'TPVC' against the manufacturer's official documentation to confirm pinout, lead finish, and RoHS compliance status. Ensure the SSOP-56 package dimensions match the target PCB footprint requirements. Confirm that the TTL input thresholds are compatible with the driving source logic family before integration into the design.

Selection Notes

Select this component when 16-bit parallel data registration is required alongside bus direction control. The FCT series offers faster switching speeds compared to standard CMOS logic. Verify that the system power supply remains stable within the 4.5 V to 5.5 V range to ensure correct operation of the internal latch and transceiver circuitry.
