Product data sheet
1. General description
The 74LVC16245A; 74LVCH16245A are 16-bit transceivers featuring non-inverting
3-state bus compatible outputs in both send and receive directions. The device features
two output enable (nOE) inputs for easy cascading and two send/receive (nDIR) inputs for
direction control. nOE controls the outputs so that the buses are effectively isolated. This
device can be used as two 8-bit transceivers or one 16-bit transceiver.
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 74LVCH16245A bus hold on data inputs eliminates the need for external pull-up
resistors to hold unused inputs.
