december 2006 rev 2 1/26 26 features low voltage power supply down to 3v 16 constant current output channels adjustable output current through external resistor serial data in/parallel data out can be driven by a 3.3v microcontroller output current: 5-80ma max clock frequency 30mhz esd protection 2.5kv hbm, 200v mm description the STP16CP05 is a monolithic, low voltage, low current power 16-bit shift register designed for led panel displays. the STP16CP05 contains a 16-bit serial-in, parallel-out shift register that feeds a 16-bit, d-type storage register. in the output stage, sixteen regulated current sources provide from 5ma to 80ma constant current to drive the leds. the output current setup time is 40ns (typ), thus improving the system performance. the leds' brightness can be controlled by using an external resistor to adjust the STP16CP05 output current. the STP16CP05 guarantees a 20v output driving capability, allowing users to connect more leds in series.the high clock frequency, 30mhz, makes the device suitable for high data rate transmission. the 3.3v voltage supply is useful in applications that interface with a 3.3v microntroller. dip-24 so-24 tssop24 tssop24 (exposed pad) STP16CP05 low voltage 16-bit constant current led sink driver www.st.com order codes part number package packaging STP16CP05b1r dip-24 15 parts per tube STP16CP05mtr so-24 1000 parts per reel STP16CP05ttr tssop24 2500 parts per reel STP16CP05xtr tssop24 exposed pad 2500 parts per reel
