74F2645
Octal Bus Transceiver
with 25Series Resistors in the Outputs
General Description
This device is an octal bus transceiver designed for asyn-
chronous two-way data flow between the A and B busses
and is functionally equivalent to the 74F645. The 25
series resistors in the outputs reduce ringing and eliminate
the need for external resistors. Both busses are capable of
sinking 12 mA, sourcing 15 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
74F2645 is a low power version of the 74F245 with 25
series resistors in the outputs.
