74ABT245  
Octal Bi-Directional Transceiver with 3-STATE Outputs  
General Description  
Features  
The ABT245 contains eight non-inverting bidirectional buff-  
ers 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 deter-  
mines 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.  
Bidirectional non-inverting buffers  
A and B output sink capability of 64 mA, source  
capability of 32 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
