Pin Name
Description
1
VIA Non-inverting logic input terminal for Driver A.
2
VIB Non-inverting logic input terminal for Driver B.
3 VDDI Input-side power supply terminal; connect to a source of 4.5 to 5.5 V, (2.7 to 5.5 V for Si8237/8).
4 GNDI Input-side ground terminal.
5 DISABLE Device Disable. When high, this input unconditionally drives outputs VOA, VOB LOW. It is
strongly recommended that this input be connected to external logic level to avoid erroneous
operation due to capacitive noise coupling.
6
NC No connection.
7
NC No connection.
8 VDDI Input-side power supply terminal; connect to a source of 4.5 to 5.5 V, (2.7 to 5.5 V for Si8237/8).
9 GNDB Ground terminal for Driver B.
10 VOB Driver B output.
11 VDDB Driver B power supply voltage terminal; connect to a source of 6.5 to 24 V.
12
NC No connection.
13
NC No connection.
14 GNDA Ground terminal for Driver A.
15 VOA Driver A output.
16 VDDA Driver A power supply voltage terminal; connect to a source of 6.5 to 24 V.
