74F640 鈥?74F645
Octal Bus Transceiver with 3-STATE Outputs
General Description
These devices are octal bus transceivers designed for
asynchronous two-way data flow between the A and B bus-
ses. Both busses are capable of sinking 64 mA, have 3-
STATE outputs, and a common output enable pin. The
direction of data flow is determined by the transmit/receive
(T/R) input. The 74F645 is a high speed/low power version
of the 74F245. The 74F640 is an inverting option of the
74F645.
