詳細說明
The MM5311N is a semiconductor integrated circuit that is commonly used in digital clocks and timing applications. It is a 8-digit LED display driver with an internal oscillator, decoder, and multiplexed display outputs. This IC is designed to drive common cathode LED displays and can support up to 8 digits with a 7-segment display format.The MM5311N features a built-in oscillator with an external resistor and capacitor for setting the frequency of the clock signal. It provides a 32.768 kHz timing reference which is commonly used in real-time clock applications. The internal BCD to 7-segment decoder makes it easy to interface with standard LED displays, while the multiplexed output scheme allows for the implementation of multi-digit displays.Other key features of the MM5311N include a power on reset circuit, a test mode for checking the display segments, and a latch enable pin for storing the data to be displayed. It operates in a wide voltage range from 3V to 15V and is typically powered by a 5V supply.
