Description
This STPIC6D595 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 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 20V and 120mA
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 2.0KV
of ESD protection when tested using the human-
body model.
The STPIC6D595 is characterized for operation
over the operating case temperature range of -
40°C to 125°C.
