DESCRIPTION

The 74AVCM162834 is an 18-bit universal bus driver. Data flow is

controlled by output enable (OE), latch enable (LE) and clock inputs

(CP).

This product is designed to have an extremely fast propagation

delay and a minimum amount of power consumption.

To ensure the high-impedance state during power up or power

down, OE should be tied to VCC through a pullup resistor (Live

Insertion).

NOTES:

1. CPD is used to determine the dynamic power dissipation (PD in µW):

PD = CPD × VCC2 × fi + S (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacitance in pF;

fo = output frequency in MHz; VCC = supply voltage in V; S (CL × VCC2 × fo) = sum of outputs.
