74ALVC16245
Low-Voltage 1.8/2.5/3.3V
16-Bit Transceiver
With 3.6 V鈥揟olerant Inputs and Outputs
(3鈥揝tate, Non鈥揑nverting)
The 74ALVC16245 is an advanced performance, non鈥搃nverting
16鈥揵it transceiver. It is designed for very high鈥搒peed, very low鈥損ower
operation in 1.8 V, 2.5 V or 3.3 V systems.
The ALVC16245 is designed with byte control. It can be operated as
two separate octals, or with the controls tied together, as a 16鈥揵it wide
function. The Transmit/Receive (T/Rn) inputs determine the direction
of data flow through the bi鈥揹irectional transceiver. Transmit
(active鈥揌IGH) enables data from A ports to B ports; Receive
(active鈥揕OW) 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.

鈥燭o ensure the outputs activate in the 3鈥搒tate condition, the output enable pins
should be connected to V

through a pull鈥搖p resistor. The value of the resistor is
determined by the current sinking capability of the output connected to the OE pin.
