DESCRIPTION
The 74LVC2244A 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 V 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 V and 5 V environment.
The 74LVC2244A is an octal non-inverting buffer/line
driver with 3-state outputs. The 3-state outputs are
controlled by the output enable input pins 1OE and 2OE.
A HIGH on pin 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 74LVC2244A is designed with 30
termination resistors in both HIGH and LOW output stages
to reduce line noise.
