DESCRIPTION
The STP16CL596 is a monolithic, low voltage, low
current power 16-bit shift register designed for
LED panel displays. The STP16CL596 contains a
16-bit serial-in, parallel-out shift register that feeds
a 16-bitD-type storage register. In the output
stage, sixteen regulated current sources were
designed to provide 15-90mA constant current to
drive the LEDs.
Compared with the STPIC6C595, the device
provides
great
flexibility
and
improved
performance in LED panel system design.

(exposed pad)
Trough an external resistor, users can adjust the
STP16CL596 output current, controlling in this
way the light intensity of LEDs.
The STP16CL596 guarantees a 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 3.3V of voltage
supply is well useful for applications that interface
any micro from 3.3V. Compared with a standard
TSSOP package, the TSSOP exposed pad
increases heat dissipation capability by a 2.5
factor.

Note: The latches circuit holds data when the LE terminal is Low.
When LE terminal is at High level, latch circuit doesn’t hold the data it passes from the input to the output.
When OE terminal is at Low level, output terminals OUT0 to OUT15 respond to the data, either ON or OFF.
When OE terminal is at High level, it switches off all the data on the output terminal.
