Driving a 7 segment display with a 4511 BCD to 7 Segment Driver

TI has taken and continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals. Device Function Package Mftr.

Efforts are underway to better integrate information from third parties. J Chandler Product code: Resistors are still needed to limit this current for a specific displays requirements.

TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release. In the datasheet for this product it states that it can directly drive an LED display, does this mean the display does not need protecting with resistors?

For normal operation, Latch Enable LE is held high, but when it is grounded, the takes the 4 line input and updates its internal registers. Device has been announced but is not in production.

Hi J Chandler, thank you for your question. Important Information and Disclaimer: Since this is being powered by a 9V battery, I am using 1.

TI has discontinued the production of the device. No TI components are authorized for use in FDA Class III or similar life-critical medical equipment unless authorized officers of the parties have executed a special agreement specifically governing such use.

Im trying to drive a single 7 segment display but i dont know how. This connection is available on pins 3 and 8. The modules we will be using have a common cathode. Each segment is identified by a cd4511bf as can be seen below as well as the pinout and schematic for reference. Using the 7 segments, you can make any decimal digit. Hi J Chandler, thank you for your dataxheet. They allow you to create temporary circuits TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

TI is not responsible or liable for such altered documentation. This provides a little over 5ma for each segment. TI assumes no liability for applications assistance or the design of Buyers’ products. The CDB types are supplied in lead hermetic dual-in-line ceramic packages F3A suffixlead dual-in-line plastic packages E suffixlead small-outline packages NSR suffixand lead thin shrink small-outline packages PW and PWR suffixes.


The photo below shows the finished circuit. We are factory specialized in making LED 7-segment display, dot-matrix display, light bar display and abnormity digital display.

Device is in production to support existing customers, but TI does not recommend using this part in a new design. This calculator will help you figure out the resistor size http: First we need to familiarize ourselves with the 7 segment module. If the voltage is too high or the resistor too low think of the wire being a resistorthe current going through the LED will exceed the maximum forward current and burn out the LED. Nonetheless, such components are subject to these terms.
