具有三态输出的 16 位缓冲器/驱动器 48-TSSOP -40 to 85
The SN54ABT16540 and SN74ABT16540A are inverting 16-bit buffers/drivers composed of two 8-bit sections with separate output-enable gates. These 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 or input is high, all corresponding outputs are in the high-impedance state.
To ensure the high-impedance state during power up or power down, 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 SN54ABT16540 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT16540A is characterized for operation from -40°C to 85°C.
