Function

Description

1

INB

Logic input.

2

VDD

High side supply voltage.

3

VSS

Low side supply voltage. VSS is also connected to the IC substrate. It is required to

connect to the most negative potential of voltage supplies.

4

INC

Logic input.

5

IND

6

GND

Logic input ground reference.

7

VL

Supply voltage for N-channel output stage.

8

OUTC

Output drivers

9

OUTD

10, 11

VH

Supply voltage for P-channel output stage.

12

OUTA

Output drivers

13

OUTB

14

VL

Supply voltage for N-channel output stage.

15

PE

Power enable logic input. When PE is high, sets the input logic threshold. When PE is

low, all outputs are at default state (see truth table) and IC in standby mode.

16

INA

Logic input.

Substrate

The IC substrate is internally connected to the thermal pad. Thermal pad and VSS

must be connected externally.
