74ALVC16245  
Low-Voltage 1.8/2.5/3.3V  
16-Bit Transceiver  
With 3.6 V–Tolerant Inputs and Outputs  
(3–State, Non–Inverting)  
The 74ALVC16245 is an advanced performance, non–inverting  
16–bit transceiver. It is designed for very high–speed, very low–power  
operation in 1.8 V, 2.5 V or 3.3 V systems.

MARKING DIAGRAM  
The ALVC16245 is designed with byte control. It can be operated as  
two separate octals, or with the controls tied together, as a 16–bit wide  
function. The Transmit/Receive (T/Rn) inputs determine the direction  
of data flow through the bi–directional 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), when HIGH, disable both A and B ports by placing them  
in a HIGH Z condition.

Second Source to Industry Standard 74ALVC16245  
To ensure the outputs activate in the 3–state condition, the output enable pins  
should be connected to V through a pull–up resistor. The value of the resistor is  
CC  
determined by the current sinking capability of the output connected to the OE pin.
