DRON(flat)

VDD = 3 V, VI = 0 V or 1 V, IO = –8 mA

Notes:

1. VIN and IIN refer to control input (OE). VI, VO, II, and IO refer to data pins.

2. All typical values are at VDD = 3.3 V (unless otherwise noted), TA = 25°C.

3. For I/O ports, the parameter IOZ includes the input leakage current.

4. This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VDD or GND.

5. Measured by the voltage drop between the D and HSD terminals at the indicated current through the switch. ON-state resistance is

determined by the lower of the voltages of the two terminals.
