Maxim Integrated (ICM7224IPL+) Display Driver, LCD 4.5 Digits

Product Overview The ICM7224IPL+ is a 4.5 digit, LCD, high speed counter/decoder/driver in 40 pin DIP package. The device has segment decoders, leading zero blanking, store and reset inputs and carry output that allows cascading of 8 or more digits. The ICM7224 directly drives a non multiplexed liquid crystal display (LCD). This counter operates with input from DC to 25MHz while using only 10µA of supply current. A schmitt trigger on the count input ensures reliable operation in noisy environments and in applications with slowly varying inputs. Typical applications include unit counter, frequency counter, tachometer, hour meter and totalizer. Supply voltage range from 3V to 6V Operating temperature range from -20°C to 85°C Supports non multiplexed interface Onborad oscillator to provide backplane frequency Low power CMOS design Oscillator input current of ±2µA Segment rise/fall time of 0.5µs at Cload=200pF and backplane rise/fall time of 1.5µs at Cload=5000pF Oscillator frequency of 19KHz (pin 36 floating) Backplane frequency of 150Hz (pin 36 floating) Applications Signal Processing Product Information No. of Digits: 4.5 No. of Segments: - Driver Case Style: DIP No. of Pins: 40Pins Supply Voltage Min: 3V Supply Voltage Max: 6V Interface Type: Non Multiplexed Operating Temperature Min: -20°C Operating Temperature Max: 85°C Product Range: - MSL: MSL 1 - Unlimited
