5 Pin Configuration and Functions DBV Package 5-Pin SOT-23 Top View Pin Function PIN DESCRIPTION NO. NAME

1 CS Chip Select input. This pin receives an active-low signal from the controller to select the device.

2 GND Ground. This is the power and signal ground return.

3 SI/O Serial Input/Output. This serial, bidirectional, data bus pin transmits and receives signals to and from the controller. Schmitt trigger input in the input mode.

4 SC Serial bus clock. This serial clock signal comes from the controller. Schmitt trigger input.

5 VDD Positive Supply Voltage. Supply a DC voltage from 2.4V to 5.5V to this pin and bypass with a 0.1-?F ceramic capacitor to ground. (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating the device beyond its rated operating conditions. (2) Soldering process must comply with Reflow Temperature Profile specifications. Refer to http://www.ti.com/packaging. (3) Reflow temperature profiles are different for lead-free and non-lead-free packages. (4) When the input voltage (VI) at any pin exceeds the power supplies (VI <

GND or VI >

VDD) the current at that pin should be limited to

5 mA.

150 °C (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) Human body model,

100 pF discharged through a 1.5 kΩ resistor. Machine model,

200 pF discharged directly into each pin. (3) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)(2) ±2000 V Charged-device model (CDM), per JEDEC specification JESD22- C101(3) ±200
