Electrical Specifications
Unless otherwise noted, all parameters are established over the operational supply voltage and temperature
range of the device as follows: T_A = -25°C to +85°C; V_DD = 2.6V to 4.8V; Parameters with MIN and/or MAX
limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested. (Continued)

DESCRIPTION
System ground.
No connection.
Supply voltage.
Production test I/O pin. Used only during production testing. Must be left floating during
normal operation.
Communication bus with weak internal pull-down to VSS. This pin is a Schmitt-trigger input
and an open-drain output. An appropriate pull-up resistor is required on the host side.
