TERMINAL FUNCTIONS
TERMINAL
I/O DESCRIPTION
NAME NO.
Bias supply input. Connect a 2-µf ceramic capacitor minimum from this pin to the GND pin as
VDD 1 I
close as possible to the device with the shortest trace lengths possible.
Inverting input. Pull IN+ to VDD in order to enable Output, when using the driver device in
IN- 2 I
Inverting configuration.
Non-inverting input. Pull IN- to GND in order to enable output, when using the driver device
IN+ 3 I
in non-inverting configuration.
OUTL 4 O 8-A sink current output of driver.
OUTH 5 O 4-A source current output of driver.
Drive voltage, output of internal linear regulator. Connect a 2-µf ceramic capacitor minimum
VREF 6 O from this pin to the GND pin as close as possible to the device with the shortest trace
lengths possible.
GND PAD 7 - Ground. All signals are referenced to this node.
