IO-Link Device Transceiver
AC Electrical Characteristics (continued)
(VCC = 18V to 36V, VL = 2.3V to 5.5V, VGND = 0V; all logic inputs at VL or GND; TA = -40NC to +85NC, unless otherwise noted. Typical
values are at VCC = 24V, VL = 3.3V, and TA = +25NC, unless otherwise noted.) (Note 2)

Note 2: All devices are 100% production tested at TA = +25NC. Limits over the operating temperature range are guaranteed by
design.
Note 3: UV is an open-drain output. Connect UV to a voltage less than 5.5V through an external pullup resistor.
Note 4: Disable time measurements are load dependent.
