For either 10-bit buffer section, the two output-enable (1OE1 and 1OE2 or 2OE1 and 2OE2) inputs must both be low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 10-bit buffer section are in the high-impedance state. 1 56 2 55 3 54 4 53 5 52 6 51 7 50 8 49 9 48 10 47 11 46 12 45 13 44 14 43 15 42 16 41 17 40 18 39 19 38 20 37 21 36 22 35 23 34 24 33 25 32 26 31 27 30 28 29 1OE2 1A1 1A2 GND 1A3 1A4 VCC 1A5 1A6 1A7 GND 1A8 1A9 1A10 2A1 2A2 2A3 GND 2A4 2A5 2A6 VCC 2A7 2A8 GND 2A9 2A10 2OE2 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 SN54ABT16827 is characterized for operation over the full military temperature range of – 55°C to 125°C. The SN74ABT16827 is characterized for operation from –40°C to 85°C.
