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.
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

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 VCC 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.

10. For CL = 50 pF, add approximately 300 ps to the AC maximum specification.
11. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
The specification applies to any outputs switching in the same direction, either HIGH−to−LOW (tOSHL) or LOW−to−HIGH (tOSLH); parameter
guaranteed by design.

1. Metric Dimensions Govern−English are in parentheses for reference only.
2. A0, B0, and K0 are determined by component size. The clearance between the components and the cavity must be within 0.05 mm min to
0.50 mm max. The component cannot rotate more than 10° within the determined cavity.
