s, duty cycle
≤

2. Negative current is defined as coming out of the
specified device pin.
3. The I
IN(OFF)
current limit guarantees against partial
turn-on of the output.
4. The V
IN(ON)
voltage limit guarantees a minimum output
source current per the specified conditions.
5. The substrate must always be tied to the most
negative point and must be at least 4.0 V below V
S
.
6. V
CC
must be equal to or less positive than V
S
.
PARTIAL SCHEMATIC
Note the UDN2588A (DIP) and the A2588SLW (SOIC) are
electrically identical and share a common terminal number
assignment.
