Digital input that determines the high/low status of the driver
when it is enabled.
Digital input that enables and disables the driver, or places the
driver in the VTT state.
Digital input that determines whether DVR EN* places the driver
in a high impedance state or actively drives to the VTT level.
Driver Output.
Unbuffered analog inputs that set the voltage level of a logical
1, 0, or VTT at the driver output.
Analog input pin which establishes the threshold for all single-
ended digital input signals.
