Subject: RE: [EE] Looking for recommendation: high-side LED display driver Good day, Alan & Jerson. I actually have several rails of DIP versions of ULN2981 sitting on the she= lf. Downside is that they are parallel-in devices, and thus need to be dri= ven by something like a shift register. Thanks for the suggestions, and please keep more coming. Many thanks! dwayne At 02:23 AM 3/8/2019, AB Pearce - UKRI STFC wrote: >Content-Transfer-Encoding: base64Looks like Microchip supply a version=20 >of this part ... > >https://www.microchip.com/wwwproducts/en/MIC2981 > > > >-----Original Message----- >From: piclist-bounces@mit.edu On Behalf Of=20 >Jerson Fernandes >Sent: 08 March 2019 03:36 >To: piclist@mit.edu >Subject: [EE] Looking for recommendation: high-side LED display driver > >Will the UDN2981 help you? >Recommended for high-side switching applications that benefit=20 >fromseparate logic and load grounds, these devices encompass load=20 >supplyvoltages to 50 V and output currents to -500 mA.
