DESCRIPTION
The STP08CDC596 is a monolithic,
medium-voltage, low current power 8-bit shift
register designed for LED panel display. The
STP08CDC596 contains a 8-bit serial-in,
parallel-out shift register that feeds a 8-bitD-type
storage register. In the output stage, eight
regulated current sources were designed to
provide 15-120mA constant current to drive the
LEDs.
The STP08CDC596 contains the built-IN error
detection feature. The device performs this
additional function without any increase of the pin
number and any change of the pin function, if
compared to the standard device without error
detection. Consequently, choosing this device
does not mean to change the footprint on the
board. To perform this functionality mode, the
device needs a digital key coming from the
Microprocessor. The STP08CDC596 is able to
detect: open and short on the LED line, short to

TSSOP16
GND, short to Led voltage supply. The data
mapping of output channels status detection is
provided by a feedback from the serial output to
the Microprocessor.
Trough an external resistor, users may adjust the
STP08CDC596 output current, controlling the light
intensity of LEDs.
The STP08CDC596 guarantees 16V output
driving capability, allowing users to connect more
LEDs in series. The high clock frequency, 25 MHz,
also satisfies the system requirement of high
volume data transmission.
The device is offered in DIP-16, SO-16 and
TSSOP-16 packages.
The STP08CDC596 is well suitable for traffic
display signs where the detection feature is
strongly required.
