FUNCTION
DE
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high, and are high impedance when DE is low. If the
driver enable function isn’t needed, connect DE to V_CC (or V_L) through a 1kΩ to 3kΩ resistor.
DI
Driver input. A low on DI forces output Y low and output Z high. Similarly, a high on DI forces output Y high and output Z low.
GND Ground connection. This is also the potential of the TDFN thermal pad.
Y
±15kV HBM, ±7kV IEC61000 (contact method) ESD Protected RS-485/422 level, noninverting transmitter output.
Z
±15kV HBM, ±7kV IEC61000 (contact method) ESD Protected RS-485/422 level, inverting transmitter output.
V_CC System power supply input (3.0V to 5.5V). On devices with a V_L pin, power-up V_CC first.
V_L
Logic-Level supply which sets the V_IL/V_IH levels for the DI and DE pins (ISL3296E, ISL3297E, ISL3298E only). Power-up this supply
after V_CC, and keep V_L ≤ V_CC.
