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. The 74ACT16827 is packaged in TI’s shrink small-outline package, which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed- circuit-board area. The 54ACT16827 is characterized for operation over the full military temperature range of –55 °C to 125°C. The 74ACT16827 is characterized for operation from –40 °C to 85°C.
