description
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 (OE1 or OE2) 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, 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 outputs, which are designed to source or sink up to 12 mA, include equivalent 25- series resistors to reduce overshoot and undershoot.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD51, except for through-hole packages, which use a trace length of zero.

All typical values are at VCC = 5 V, TA = 25°C. This data sheet limit may vary among suppliers. § Not more than one output should be tested at a time, and the duration of the test should not exceed one second. ¶ This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
