16-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTS

These 16-bit Buffers and bus drivers SN54AHC16540 SN74AHC16540 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 55C to 125C. The SN74AHC16540 is characterized for operation from 40C to 85C. By Texas Instruments
