4 / 76 page  Si 24 00 4 Rev. 0.95 Electrical Specifications Table 1. Recommended Operating Conditions Parameter1 Symbol Test Condition Min2 Typ Max2 Unit Ambient Temperature TA K-Grade 0 25 70 °C Ambient Temperature TA B-Grade –40 25 85 °C Si2400 Supply Voltage, Digital3 VD 3.0 3.3/5.0 5.25 V Notes: 1. The Si2400 specifications are guaranteed when the typical application circuit (including component tolerance) and any Si2400 and any Si3015 are used. See Figure 3 on page 9 for typical application circuit. 2. All minimum and maximum specifications are guaranteed and apply across the recommended operating conditions. Typical values apply at nominal supply voltages and an operating temperature of 25 °C unless otherwise stated. 3. The digital supply, VD, can operate from either 3.3 V or 5.0 V. The Si2400 interface supports 3.3 V logic when operating from 3.3 V. The 3.3 V operation applies to both the serial port and the digital signals CTS, CLKOUT, GPIO1–4, and RESET. Table 2.
