SN74AHC16540DGGR

16位缓冲器/驱动器，具有三态输出 16-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTS

description

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.
