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.
The ALVC16245 is designed with byte control. It can be operated as

Substantially Reduces System Power Requirements
• Latchup Performance Exceeds $250 mA @ 125°C
• ESD Performance: Human Body Model >2000 V; Machine Model >200 V
• 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_CC through a pull−up resistor. The value of the resistor is
determined by the current sinking capability of the output connected to the OE pin.
