MC14LC5003/5004 are 128-segment, multiplexed-by-four LCD drivers. The MC14LC5003 uses a serial interface data input protocol, while the MC14LC5004 uses an IIC interface and has a 'read mode'. The drivers accept data from a microprocessor or other serial data source to drive each segment of the LCD. They are low cost, independently addressable, and have other features.
The MC14LC5003 and MC14LC5004 are low-cost, 128-segment, multiplexed-by-four liquid crystal display (LCD) drivers designed for segmented alphanumeric, bar graph, dot matrix, and custom displays. The two devices are functionally identical except for their data input protocols: the MC14LC5003 uses a serial interface, while the MC14LC5004 utilizes an IIC interface with read mode capability.
The devices operate with a supply voltage between 2.7 and 5.5 volts.
The quiescent supply current is 30 microamperes when the voltage is 2.7 volts.
The devices operate from -40 to +85 degrees Celsius and store from -65 to +150 degrees Celsius.
