Description
This STPIC6C595 is a monolithic, medium-
voltage, low current power 8-bit shift register
designed for use in systems that require relatively
moderate load power such as LEDs. The device
contains a built-in voltage clamp on the outputs
for inductive transient protection. Power driver
applications include relays, solenoids, and other
low-current or medium-voltage loads.
The device contains an 8-bit serial-in, parallel-out
shift register that feeds an 8-bit D-type storage
register. Data transfers through both the shift and
storage register clock (SRCK) and the register
clock (RCK), respectively. The device transfers
data out the serial output (SER OUT) port on the
rising edge of SRCK. The storage register
transfers data to the output buffer when shift
register clear (CLR) is high. When CLR is low, the
input shift register is cleared. When output enable
(G) is held high, all data in the output buffer is
held low and all drain output are off. When G is
held low, data from the storage register is
transparent to the output buffer.

When data in the output buffers is low, the DMOS
transistor outputs are off. When data is high, the
DMOS transistor outputs have sink-current
capability. The SER OUT allows for cascading of
the data from the shift register to additional
devices.
Output are low-side, open-drain DMOS
transistors with output ratings of 33 V and 100 mA
continuous sink-current capability. Each output
provides a 250 mA maximum current limit at
T
C
= 25 °C. The current limit decreases as the
junction temperature increases for additional
device protection. The device also provides up to
1.5 kV of ESD protection when tested using the
human-body model and 150 V machine model.
The STPIC6C595 is characterized for operation
over the operating case temperature range of
-40 °C to 125 °C.

Maximum rating
Stressing the device above the rating listed in the “absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
