Functional Description
The CY74FCT163827 is a 20-bit buffer/line driver that provides
high-performance bus interface buffering for wide data/address
paths or buses carrying parity. It can be used as a single 20-bit
bufferortwo10-bitbuffers.Each10-bitbufferhasapairofNANDed
OE for increased flexibility.
The CY74FCT163827 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 inputs
and outputs were designed to be capable of being driven by
5.0V buses, allowing its use in mixed voltage systems as a
translator. The outputs are also designed with a power-off
disable feature enabling its use in applications requiring live
insertion.
