The max6955 is a compact display driver that interfaces microprocessors to a mix of 7 segment 14 segment and 16 segment led displays through an i 2 c compatible 2 wire serial interface.
7 segment led display driver ic.
If you have other indicator needs then of course they will also drive lots of leds in the other digit positions.
Circuit for interfacing a 7 segment display with arduino without using any driver ic you must connect the resistors between the led pins and the arduino digital i o pins.
7 segment display lcd drivers are available at mouser electronics.
The voltage and current capability of the driver stage determines which type of 7 segmnet numerical displays can be driven.
Cd4511 7 segment driver ic.
You can connect the led pins with any of the arduino s digital i o pins.
The max6955 drives up to 16 digits 7 segment 8 digits 14 segment 8 digits 16 segment or 128 discrete leds while functioning from a supply voltage as low as 2 7v.
A typical high voltage cmos ic can operate up to a maximum of 20 v and can source up to 25 ma at each output.
7446 is a bcd to 7 segment display driver ic with active low outputs.
The ic is stand alone and requires no external components other than the led current limiting resistors.
Cd4511 is a bcd to 7 segment latch decoder driver ic formed with cmos logic and npn bipolar transistor output devices on an immovable structure.
All output of the ic have complete ripple blanking and requires no external driver transistors.
This makes it possible to drive led displays low voltage fluorescent displays and even incandescent displays.
Mouser offers inventory pricing datasheets for 7 segment display lcd drivers.
