For either 10-bit buffersection, the two output-enable (1OE1 and 1OE2or 2OE1 and 2OE2) inputs must both be low forthe corresponding Y outputs to be active. If eitheroutput-enable input is high, the outputs of that10-bit buffer section are in the high-impedancestate.The 74ACT16827 is packaged in TI’s shrinksmall-outline package, which provides twice theI/O pin count and functionality of standardsmall-outline packages in the same printed-circuit-board area.1OE11Y11Y2GND1Y31Y4VCC1Y51Y61Y7GND1Y81Y91Y102Y12Y22Y3GND2Y42Y52Y6VCC2Y72Y8GND2Y92Y102OE11234 5678910111213141516171819202122232425262728565554535251504948474645444342414039383736353433323130291OE21A11A2GND1A3A14VCC1A51A61A7GND1A81A91A102A12A22A3GND2A42A52A6VCC2A72A8GND2A92A102OE2The 54ACT16827 is characterized for operation over the full military temperature range of –55°C to 125°C.
