General description

The 74LVC245A; 74LVCH245A are 8-bit transceivers featuring non-inverting 3-state bus

compatible outputs in both send and receive directions. The device features 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.

Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be

applied to the outputs. These features allow the use of these devices in mixed

3.3 V and 5 V applications.

The 74LVCH245A bus hold on data inputs eliminates the need for external pull-up

resistors to hold unused inputs.
