Octal Bi-Directional Transceiver with 3-STATE Outputs
Features
■ Bidirectional non-inverting buffers
■ A and B output sink capability of 64mA, source
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
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.
