description
This 16-bit buffer/driver is designed for 1.65-V to
3.6-V VCC operation.
The SN74ALVCH16541 is a noninverting 16-bit
buffer composed of two 8-bit sections with
separate output-enable signals. For either 8-bit
buffer section, the output enables (1OE1 and
1OE2 or 2OE1 and 2OE2) must both 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.
Active bus-hold circuitry is provided to hold
unused or floating data inputs at a valid logic level.
The SN74ALVCH16541 is characterized for
operation from –40
°C to 85°C.
