- 2.7V to 5.5V Supply: 7-8 Ω (typical), 28-40 Ω (maximum)
️· rON Matching Between Channels (ΔrON): Consistency between channels is important for balanced performance.
- 5V Supply: 0.8-2 Ω (typical)
- 2.7V to 5.5V Supply: 0.8-2 Ω (typical)
️· rON Flatness (RFLAT(ON)): Describes variation of ON-resistance across the voltage range.
- 5V Supply: 7-8 Ω
- 2.7V to 5.5V Supply: 7-8 Ω
️· Leakage Currents (OFF State): Lower is better (less current when the switch is OFF).

3. Dynamic Characteristics (Switching Speed)

️· Turn-ON Time (tON): How long it takes for the switch to turn ON.
- 5V Supply: 28-40 ns (typical)
- 2.7V to 5.5V Supply: 28-40 ns (typical)
️· Turn-OFF Time (tOFF): How long it takes for the switch to turn OFF.
- 5V Supply: 20-30 ns (typical)
- 2.7V to 5.5V Supply: 20-30 ns (typical)
️· Break-Before-Make Time Delay (tD): Important for avoiding signal contention.
- 5V Supply: 10 ns (typical)
- 2.7V to 5.5V Supply: 10 ns (typical)
️· Charge Injection (Q): A measure of the charge transferred during switching. Lower is generally better.
- 5V Supply: 3 pC (typical)
- 2.7V to 5.5V Supply: 3 pC (typical)
️· OFF Isolation: How well the switch blocks signals when OFF.
- 76 dB
️· Power Supply Rejection Ratio (PSRR): A measure of how well the circuit rejects noise on the supply line.
- 5V Supply: 60 dB
- 2.7V to 5.5V Supply: 60 dB

4. Power Supply Characteristics

️· Power Supply Range: 2.7V to 15V (for the 2.7V to 5.5V condition, it's functionally limited by the specified operation at 3.0V - 3.6V)
️· Positive Supply Current: How much current the device draws from the supply.
- 5V Supply: 0.0001 µA (typical)
- 2.7V to 5.5V Supply: 0.0001 µA (typical)
️· Digital Input Voltages:
- Input Voltage Low (VINL): 0.8V
- Input Voltage High (VINH): 2.4V (for both supply voltages)
️· Input Current: ±1 µA for both supply voltages.

Key Differences between 5V and 2.7V-5.5V operation

️· ON Resistance: Significantly lower for the 2.7-5.5V operation.
️· Supply Current: Similar supply current draw for both operation.
️· Functional Voltage Range: While the supply voltage range is wider for 2.7V-5.5V, the device is designed to operate reliably and with the performance outlined in the datasheet with a voltage between 3.0-3.6V.
