General Description
The ’ABT245 contains eight non-inverting bidirectional buffers with TRI-STATE outputs and is intended for bus-oriented applications. Current sinking capability is 48 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.

Features
■ Bidirectional non-inverting buffers
■ A and B output sink capability of 48 mA, source capability of 24 mA
■ Guaranteed output skew
■ Guaranteed multiple output switching specifications
■ Output switching specified for both 50 pF and 250 pF 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
■ Non-destructive hot insertion capability
■ Disable time is less than enable time to avoid bus contention
■ Standard Microcircuit Drawing (SMD) 5962-9214801
