Test output in default mode
For internal use. Must be left unconnected
Select between slow (open, low: VSS) and fast (high) mode. Internal pull-
down resistor.
Negative Supply Voltage (GND)
OTP Programming Input and Data Input for Daisy Chain mode.
Internal pull-down resistor (~74kΩ). Should be connected to VSS if
programming is not used.
Clock Input of Synchronous Serial Interface; Schmitt-Trigger input
