These 16-bit buffers and bus drivers provide a high-performance bus interface for wide data paths.
The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1\ or OE2\) input is high, all corresponding outputs 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 SN54AHC16540 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74AHC16540 is characterized for operation from -40°C to 85°C.
