74ABT245 Octal Bi-Directional Transceiver with 3-STATE Outputs
Features
Bidirectional non-inverting buffers A and B output sink capability of 64mA, source

General Description
The ABT245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for busoriented 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 placing 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
