DESCRIPTION
B6
The 74F545 is an 8-bit, 3-State, high speed transceiver. It provides
bidirectional drive for the bus-oriented microprocessor and digital
communications systems. Straight through bidirectional transceivers
are featured, with 24mA bus drive capability on the A ports and
64mA bus drive capability on the B ports. One input,

Transmit/Receive (T/R) determines the direction of logic signals
through the bidirectional transceiver. Transmit enables data from A
ports to B ports; Receive enables data from B ports to A ports. The
Output Enable input disables both A and B ports by placing them in
a 3-State condition. The 74F545 performs the same function as the
74F245, the only difference being package pin assignment.

NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value under the recommended operating conditions for the applicable type.
2. All typical values are at V = 5V, T = 25°C.

3. Not more than one output should be shorted at a time. For testing I , the use of high-speed test apparatus and/or sample-and-hold
OS
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I should be performed last.

4. Measure I with outputs open.
