Product specification

PNP resistor-equipped double transistor

PUMB4

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.
