Working Principles

The SN74ALVTH16240GR is designed to facilitate bidirectional data communication between two buses with different voltage levels. It acts as a buffer/driver, allowing data transmission in both directions while providing voltage level translation.

The IC features tri-state outputs, which means that when the control inputs are inactive, the outputs enter a high impedance state, effectively disconnecting the IC from the bus. This feature enables multiple devices to share the same bus without interfering with each other.

The SN74ALVTH16240GR also incorporates ESD protection, safeguarding the IC against Electrostatic Discharge events that could potentially damage the device.
