54F 74F545 Octal Bidirectional Transceiver with TRI-STATE Outputs
May 1995
54F 74F545 Octal Bidirectional
Transceiver with TRI-STATE Outputs
General Description
The 鈥橣545 is an 8-bit TRI-STATE high-speed transceiver It
provides bidirectional drive for bus-oriented microprocessor
and digital communications systems Straight through bidi-
rectional transceivers are featured with 24 mA (20 mA Mil)
bus drive capability on the A ports and 64 mA (48 mA Mil)
bus drive capability on the B ports
One input Transmit Receive (T R) determines the direction
of logic signals through the bidirectional transceiver Trans-
mit enables data from A ports to B ports Receive enables
data from B ports to A ports The Output Enable input dis-
ables both A and B ports by placing them in a TRI-STATE
condition
