9 / 46 page  Si4421 9 GENERAL DEVICE SPECIFICATIONS All voltages are referenced to Vss, the potential on the ground reference pin VSS. Absolute Maximum Ratings (non-operating) Symbol Parameter Min Max Units Vdd Positive supply voltage -0.5 6 V Vin Voltage on any pin (except RF1 and RF2) -0.5 Vdd+0.5 V Voc Voltage on open collector outputs (RF1, RF2) -0.5 Vdd+1.5 (Note 1) V Iin Input current into any pin except VDD and VSS -25 25 mA ESD Electrostatic discharge with human body model 1000 V Tst Storage temperature -55 125 oC Tld Lead temperature (soldering, max 10 s) 260 oC Recommended Operating Range Symbol Parameter Min Max Units Vdd Positive supply voltage 2.2 3.8 V Voc Voltage range on open collector outputs (RF1, RF2) Vdd-1.5 (Note 2) Vdd+1.5 V Top Ambient operating temperature -40 85 oC Note 1: The voltage on RF1 and RF2 pins can be higher than the actual Vdd but cannot exceed 7 V. Note 2: The actual voltage on RF1 and RF2 pins can be lower than the current Vdd but never should go below 1.2 V. |
