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 bidirec- tional 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 s Non-inverting buffers s Bidirectional data path s A and B output sink capability of 64 mA, source capability of 15 mA s Guaranteed pin-to-pin skew, multiple output switching and 250 pf delay Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
