DESCRIPTION
The 74LVCH16541A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3V or 5V devices. In 3-State operation, outputs can handle 5V. These features allow the use of these devices in a mixed 3.3V/5V environment. The 74LVCH16541A is a 16-bit inverting buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs 1OEn and 2OEn. A HIGH on nOEn causes the outputs to assume a high impedance OFF-state. To ensure the high impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

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