Description

The CY29FCT52T has two 8-bit back-to-back registers that store data flowing in both directions between two bidirectional buses. Separate clock, clock enable, and 3-state output-enable signals are provided for each register. Both A outputs and B outputs are specified to sink 64 mA.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
