The 74ALVCH16245 is an advanced performance, noninverting 16bit transceiver. It is designed for very highspeed, very lowpower operation in 1.8 V, 2.5 V or 3.3 V systems. The 74ALVCH16245 is designed with byte control. It can be operated as two separate octals, or with the controls tied together, as a 16bit wide function. The Transmit/Receive (T/Rn) inputs determine the direction of data flow through the bidirectional transceiver. Transmit (activeHIGH) enables data from A ports to B ports; Receive (activeLOW) enables data from B to A ports. The Output Enable inputs (OEn), when HIGH, disable both A and B ports by placing them in a HIGH Z condition. The data inputs include active bushold circuitry, eliminating the need for external pullup resistors to hold unused or floating inputs at a valid logic state. |
