The CY74FCT162827T and CY74FCT16827T are 20-bit buffers/line drivers that provide high-performance bus interface buffering for wide data/address paths or buses carrying parity. They have power-off disable outputs that allow for live insertion. They are ideally suited for driving high-capacitance loads and low-impedance backplanes.
This document provides technical specifications and electrical characteristics for the CY74FCT16827T and CY74FCT162827T 20-bit buffer/line drivers. These devices are designed for high-performance bus interface buffering, capable of operating as a single 20-bit buffer or two 10-bit buffers. They feature power-off disable outputs to permit live insertion of boards and include edge-rate control circuitry for improved noise characteristics.
