NPN resistor-equipped transistor PDTC144ET
FEATURES
• Built-in bias resistors R1 and R2
(typ. 47 kΩ each)
• 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.
