10-ch, 4.5-V to 5.5-V buffers with TTL-compatible CMOS inputs and 3-state outputs

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 'ABT827 provide true data at the outputs.

When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, 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 SN54ABT827 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT827 is characterized for operation from -40°C to 85°C.
