DESCRIPTION
The 74LVC245A/74LVCH245A 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 74LVC245A/74LVCH245A is an octal transceiver with
non-inverting 3-state bus compatible outputs in both send
and receive directions.
The 74LVC245A/74LVCH245A has an output enable (OE)
input for easy cascading and a send/receive (DIR) input for
direction control. OE controls the outputs so that the buses
are effectively isolated.
