ICM7243BIPLZ

INTERSIL ICM7243BIPLZ LED Driver, 4.75V to 5.25V input, 25Outputs, 400mV/30mA out, DIP-40

The is a 8-character microprocessor-compatible Display Decoder Driver provides all the circuitry required to interface a microprocessor or digital system to a 14-segment or 16-segment display. It is primarily intended for use in microprocessor systems, where it minimizes hardware and software overhead. Incorporated on-chip are a 64-character ASCII decoder, 8 x 6 memory, high power character and segment drivers and the multiplex scan circuitry. 6-bit ASCII data to be displayed is written into the memory directly from the microprocessor data bus. In the sequential access mode the first entry is stored in the lowest location and displayed in the left-most character position. Each subsequent entry is automatically stored in the next higher location and displayed to the immediate right of the previous entry. A Display FULL signal is provided after 8 entries, this signal can be used for cascading devices together.
