di gital transistors (built-in resistors) dtc143xm/DTC143XE/dtc143xua /dtc143xca/dtc143xka/dtc143xsa digital transistor (npn) features 1) built-in bias resistors enable the configurati on of an inverter circuit without connecting external input resistors (see equivalent circuit). 2) the bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the inpu t. they also have the advantage of almost completely 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 to-92s sot-23 sot-23-3l DTC143XE dtc143xua dta114eca dtc143xca dtc143xka dtc143xsa addreviated symbol: 43 addreviated symbol: 43 addreviated symbol: 43 addreviated symbol: 43 sot- 7 23 dta114eca dtc143x m addreviated symbol: 43 tiger electronic co.,ltd
