Philips Semiconductors
NPN resistor-equipped double transistor
Product specification
PUMH4
FEATURES
• Transistors with built-in bias resistor R1
(typ. 10 kΩ)
• No mutual interference between the transistors
• Simplification of circuit design
• Reduces number of components and board space.
APPLICATIONS
• Especially suitable for space reduction in interface and
driver circuits
• Inverter circuit configurations without use of external
resistors.
