The CY74FCT16827T 20-bit buffer/line driver and the CY74FCT162827T 20-bit buffer/line driver provide high-performance bus interface buffering for wide data/address paths or buses carrying parity. These parts can be used as a single 20-bit buffer or two 10-bit buffers. Each 10-bit buffer has a pair of NANDed OE\ for increased flexibility.

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.

The CY74FCT16827T is ideally suited for driving high-capacitance loads and low-impedance backplanes.

The CY74FCT162827T has 24-mA balanced output drivers with current-limiting resistors in the outputs. This reduces the need for external terminating resistors and provides for minimal undershoot and reduced ground bounce. The CY74FCT162827T is ideal for driving transmission lines.
