Product Summary
The HT1668 is an LED Controller driven on a 1/7 to 1/8 duty factor. Eleven segment output lines, six grid output lines, 1 segment/grid output lines, one display memory, control circuit , key scan circuit are all incorporated into a single chip to build a highly reliable peripheral device for a single chip microcomputer. Serial data is fed to HT1668 via a four-line serial interface. Housed in a 24-pin SO Package, HT1668 pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages. The HT1668 is ideal for: Micro-computer Peripheral Device, VCR set and Combi set.
