The 3-state control gate is a 2-input NOR such that if either output-enable (OE1 or OE2) input is high, all
ten outputs are in the high-impedance state.
The SN74ALS29827 provides true data and the SN74ALS29828 provides inverted data at their respective
outputs.
The SN74ALS29827 and SN74ALS29828 are characterized for operation from 0°C to 70°C.
