Pin Descriptions

PIN NUMBER

PIN SYMBOL

FUNCTION

1VL

Logic-Level supply which sets the VIL/VIH levels for the DI and DE pins. Power-up this supply after VCC, and keep VL

≤ VCC.

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 VCC (or VL) through a 1kΩ to 3kΩ resistor.

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.

4, 5

GND

Ground connection. This is also the potential of the TDFN thermal pad.

±15kV HBM, ±7kV IEC61000 (contact method) ESD Protected RS-485/422 level, noninverting transmitter output.

±15kV HBM, ±7kV IEC61000 (contact method) ESD Protected RS-485/422 level, inverting transmitter output.

8VCC

System power supply input (3.0V to 5.5V). On devices with a VL pin, power-up VCC first.
