DESCRIPTION

74LVC245A;

74LVCH245A

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.
