These 16-bit buffers and bus drivers SN54AHCT16540 provide ahigh-performance bus interface for wide datapaths.
The 3-state control gate is a 2-input AND gate withactive-low inputs so that if either output-enable(OE1 or OE2) input is high, all correspondingoutputs 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 SN54AHCT16540 is determined by the current-sinking capability of the driver.
The SN54AHCT16540 is characterized for operation over the full military temperature range of 55°C to 125°C.
The SN74AHCT16540 is characterized for operation from 40°C to 85°C.
