DESCRIPTION
The 74LVC241A is a high-performance, low-power, low-voltage,
Si-gate CMOS device and superior to most advanced CMOS
compatible TTL families.
Inputs can be driven from either 3.3 V or 5 V devices. In 3-State
operation, outputs can handle 5 V . This feature allows the use of
these devices as translators in a mixed 3.3 V/5 V environment.
The 74LVC241A is an octal non- inverting buf fer/li ne driver with 3-State
outputs. The 3-State outputs are controlled by the output enable inputs
1OE
and 2OE. Schmitt-trigger action at all inputs makes the circuit
highly tolerant for slower input rise and fall times.
