1. General description
2. Features
The 74LVCH322245A is a 32-bit transceiver featuring non-inverting 3-state bus
compatible outputs in both send and receive directions. The device features four output
enable (nOE) inputs for easy cascading and four send/receive (nDIR) inputs for direction
control. Pin nOE controls the outputs so that the buses are effectively isolated. The device
is designed with 30
reduce line noise.
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.
To ensure the high-impedance state during power-up or power-down, pin nOE should be
tied to V
the current-sinking capability of the driver.
Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused
inputs.
