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 corresponding outputs are in the high-impedance state. The 74ACT16540 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 54ACT16540 is characterized for operation over the full military temperature range of 55C to 125C. The 74ACT16540 is characterized for operation from 40C to 85C. FUNCTION TABLE
