DESCRIPTION

The STP16C596A is a monolithic,

medium-voltage, low current power 16-bit shift

STP16C596A 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 are designed to provide

15-120mA constant current to drive the LEDs.

The serial output change state on the falling edges

of clock, this special feature will provide an

improved performance of the application when the

clock signal is skewed because the daisy chain is

too long.

(exposed pad)

Through an external resistor, users may adjust the

STP16C596A output current, controlling in this

way the light intensity of LEDs.

The STP16C596A guarantees a 16V output

driving capability, allowing users to connect more

LEDs in series. The high clock frequency, 25 MHz,

also satisfies the system demand for high volume

data transmission. Compared with a standard

TSSOP package, the TSSOP exposed pad

increases heat dissipation capability by a 2.5

factor.
