DESCRIPTION
L9823 is a Octal Low-Side Driver Circuit, dedicated
for automotive applications. Output voltage clamping
is provided for flyback current recirculation, when in-
ductive loads are driven. Chip Select and cascadable
Serial 8-bit Interface for outputs control and diagnos-
tic data transfer.
SO24 (20+2+2)
