di gital transistors (built-in resistors) dtc144em/dtc144ee/dtc144eua DTC144ECA/dtc144eka/dtc144esa digital transistor (npn) features 1. built-in bias resistors enable the configuration of an inverter circui t without connecting external input resistors(see equivalent circuit) 2. the bias resistors consist of thin -film resistors with complete isolati on to allow negative biasing of the input. they also have the advantage of almost co mpletely eliminating parasitic effects 3. only the on/off conditions need to be set for operation, making device design easy pin connenctions and marking sot-523 sot-323 sot-23 to-92s sot-23 sot-23-3l dtc144ee dtc144eua dta114eca DTC144ECA dtc144eka dtc144esa addreviated symbol: 26 addreviated symbol: 26 addreviated symbol: 26 addreviated symbol: 26 sot- 7 23 dta114eca dtc144e m addreviated symbol: 26 2012-0 willas electronic corp.
