... CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The IN74HC245A is a 3-state noninverting transceiver that is used for 2-way asynchronous communication between data buses. The device has an active-low Output Enable pin, which is used to place the I/O ports into high-impedance states ...
