DGG, DGV, OR DL PACKAGE
This 16-bit buffer/driver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVCH16541A is a noninverting 16-bit buffer composed of two 8-bit sections with separate
output-enable signals. For either 8-bit buffer section, the two output-enable (1OE1 and 1OE2 or 2OE1 and
2OE2) inputs must be low for the corresponding Y outputs to be active. If either output-enable input is high, the
outputs of that 8-bit buffer section are in the high-impedance 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.
