74LVC244A; 74LVCH244A Octal Buffer/line Driver With 5 V Tolerant Inputs/outputs (3-state)

The 74LVC244A 74LVCH244A is a high performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. Inputs CAN be driven from either 3.3 or 5 V devices. In 3-state operation, outputs CAN handle 5 V. These features allow the use of these devices as translators in a mixed 3.3 and 5 V environment. The 74LVC244A 74LVCH244A is an octal non-inverting Buffer Line Driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times. The 244 is functionally identical to the 240, but the 240 has inverting outputs.
