These 16-bit buffers and bus drivers provide a
high-performance bus interface for wide data
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.

SN74AHC16540 . . . DGG, DGV, OR DL PACKAGE
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.
