PHILIPS PUMH4 NPN resistor-equipped double transistor handbook

PUMH4 is an NPN resistor-equipped double transistor with built-in bias resistor R1 (typical value 10 kΩ). There is no mutual interference between the transistors, simplifying circuit design and reducing the number of components and board space. It is especially suitable for space reduction in interface and driver circuits, and can be used in inverter circuit configurations without the use of external resistors.
