IDT74FCT640ATD

快速CMOS八路双向收发器 FAST CMOS OCTAL BIDIRECTIONAL TRANSCEIVERS

DESCRIPTION:

The IDT octal bidirectional transceivers are built using an advanced dual metal CMOS technology. The FCT245T/FCT2245T, FCT640T and FCT645T are designed for asynchronous two-way communication between data buses. Thetransmit/receive T/R input determines the direction of data flow through the bidirectional transceiver.
