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. 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 pins for increased flexibility. The outputs are designed with a power-off disable feature to allow for live insertion of boards. The CY74FCT16827T is ideally suited for driving high-capacitance loads and low-impedance backplanes. The CY74FCT162827T has 24mA balanced output drivers.
The CY74FCT16827T and CY74FCT162827T are 20‑bit buffer/line driver devices designed for high‑performance bus interfacing, capable of handling wide data/address paths and parity. They offer power‑off disable outputs for live insertion, edge‑rate control, and low‑noise operation.
