description

The ’AHC16541 devices are noninverting 16-bit

buffers 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.

The SN54AHC16541 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74AHC16541 is characterized for operation from –40°C to 85°C.
