Texas Instruments lm3914 LED Lighting Drivers are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for Texas Instruments lm3914 LED Lighting Drivers. I'm designing a circuit with an LM3914 dot/bar display driver and want to shut off the entire bank of LEDs based on conditions in the circuit. I'm having some difficulty turning off the driver from the information in the datasheet. The LM3914 doesn't have an "enable" pin, but the datasheet states the following on page 19: You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read. Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them. Oct 21, 2010 · The problem is when I switch to the 2 delay modes, the 3915 working the "delay" LED is not bright enough to see at a respectable distance, and if it's left alone long enough it begins to mess with the regular VU meter. The regular VU is connected as the "Low cost 60dB display" shown in the data sheet.
