These 10-bit buffers or bus drivers provide a high-performance bus interface for wide data paths or buses carrying parity.
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 ten outputs are in the high-impedance state. The 'ABT2827 provide true data at their outputs.
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 outputs, which are designed to source or sink up to 12 mA, include equivalent 25- series resistors to reduce overshoot and undershoot.
The SN54ABT2827 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT2827 is characterized for operation from -40°C to 85°C.
