General Description
The ABT245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus-
oriented applications. Current sinking capability is 64 mA
on both the A and B ports. The Transmit/Receive (T/R)
input determines the direction of data flow through the
bidirectional transceiver. Transmit (active HIGH) enables
data from A Ports to B Ports; Receive (active LOW)
enables data from B Ports to A Ports. The Output Enable
input, when HIGH, disables both A and B ports by plac-
ing them in a HIGH Z condition.
capability of 32mA
Guaranteed output skew
Guaranteed multiple output switching specifications
Output switching specified for both 50pF and 250pF
loads
Guaranteed simultaneous switching, noise level and
dynamic threshold performance
Guaranteed latchup protection
High-impedance, glitch-free bus loading during entire
power up and power down cycle
Nondestructive, hot-insertion capability
Disable time is less than enable time to avoid bus
contention
