CY74FCT16652ATPVC

Overview

The CY74FCT16652ATPVC 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 has a maximum power dissipation of 1 W. The component is housed in an SSOP-56 package and supports surface-mount installation. It functions as a non-inverting bus transceiver and register, containing two circuits across sixteen channels.

Feature Summary

• Integrates registered bus transceiver functionality for data latching and transmission
• Provides three-state outputs to facilitate bus line isolation
• Supports TTL logic level compatibility for inputs and outputs

Applications

• High-speed data acquisition systems requiring parallel data buffering
• Memory interface circuits utilizing registered bus architectures
