LESHAN RADIO COMPANY, LTD.
Digital transistors (built-in resistors)
• Features
1)Built-in bias resistors enable the configuration of an inverter circuit without
connecting external input resistors.
2) The bias resistors consist of thinfilm resistors with complete isolation to allow
positive biasing of the input,and parasitic effects are almost completely
eliminated.
3) Only the on/off conditions need to be set for operation, making device design
easy.
4) Higher mounting densities can be achieved.
