BCT***8S/M/T/F is **-channel constant-current driver for LED displays with *-bit output current gain control. The output current value can also be set using an external resistor. BCT***8S/M/T/F contains a serial buffer and a **-bit data latches, which convert serial data into parallel output format. At BCT***8S/M/T/F output stage, sixteen regulated current ports are designed to provide constant current sinks for driving LEDs within a wide range of LED forward voltage variations. BCT***8S/M/T/F provides a clock frequency of *5MHz which satisfies the system requirements of high volume data transmission. Features • *6 constant current output channels • Constant current output range: 4mA ~ *0mA • Output current adjustable through an external resistor • *-bit programmable output current control • Output current accuracy: between channels: �1.5%, between ICs : �3% • *5MHz clock frequency • Fast response of output current, OE Pulse width: *0nS • Pb-free Package: SSOP*4(**0) SOP*******1.0 or SOP*******1.*7 Applications • Variable Message Signpost • Channel Signs • Information Display Board • LED Large Display Panel
