Microchip TC7117CPL PDIP Display Driver, 24 Segment, 40 Pin, 5 V

The Microchip 3 digit CMOS analog-to-digital converter (ADC) containing all the active components necessary to construct a 0.05% resolution measurement system. Seven-segment decoders, polarity and digit drivers, voltage reference, and clock circuit are integrated on-chip. They drives common anode light emitting diode (LED) displays directly with an 8mA drive current per segment.

Display Hold Function
