M74LCX16245DTR2G

The M74LCX16245DTR2G is a low voltage CMOS 16-bit Transceiver operates from a 2.3 to 3.6V supply. The device is byte controlled. Each byte has separate output enable inputs which can be tied together for full 16-bit operation. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. The MC74LCX16245 is suitable for memory address driving and all TTL level bus oriented transceiver applications. 4.5ns maximum propagation delays support high performance applications. Current drive capability is 24mA at both A and B ports. The transmit/receive (T/R barn) inputs determine 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 to A ports. The output enable inputs (OEn) bar, when HIGH, disable both A and B ports by placing them in a HIGH Z condition.
