7 Segment Led Display Driver Ic

This makes it possible to drive led displays low voltage fluorescent displays and even incandescent displays.

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. 7 segment display lcd drivers are available at mouser electronics. 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.

By far the best and cheapest way to drive seven segment displays such as this is to use multiplexed drivers like the ams as1108 4 digit or the maxim max7219 8 digit constant current drivers even if you only need a couple of displays. 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. 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. 7446 is a bcd to 7 segment display driver ic with active low outputs.

This ic is used where we need to driving common cathode displays like 7 segment display low voltage fluorescent display and incandescent display. The voltage and current capability of the driver stage determines which type of 7 segmnet numerical displays can be driven. Mouser offers inventory pricing datasheets for 7 segment display lcd drivers. Cd4511 7 segment driver ic.

All output of the ic have complete ripple blanking and requires no external driver transistors. 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. Tweaking the value of these resistors can help increase decrease the brightness of the leds.
