DESCRIPTION
The 74LVC240A 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 3.3V or 5V devices. In 3-State
operation, outputs can handle 5V. These features allow the use of
these devices as translators in a mixed 3.3V/5V environment.
The ‘240A 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 ’240’ is functionally identical to the ’244’, but the ’244’ has
inverting outputs.
