description
The ’AHCT16541 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 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 V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54AHCT16541 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74AHCT16541 is characterized for operation from –40
°
C to 85
°
C.
