U336M Integrated Circuit

The U336M integrated circuit (often associated with manufacturers such as Telefunken or TEMIC) is a bipolar integrated circuit historically used as a proximity switch or level/proximity detector (proximity switch / touch sensor).

Here are the main technical specifications:

• Main Function: Capacitive proximity sensor / Touch Switch.
• Technology: Bipolar.
• Supply Voltage ($V_s$): Typically 4.5V to 15V DC (common range for this IC family).
• Output Current: Open-collector output stage or with integrated transistor, suitable for driving external loads such as relays, LEDs or TTL/CMOS logic via pull-up resistors.
• Sensitivity: Adjustable via external components (capacitors and resistors) connected to the sensing pin to detect capacitance variations due to the proximity of an object or human touch.
• Operating Temperature: Generally -20°C to +85°C (industrial standard for ICs of this era).
• Package: Usually available in an 8-pin DIP package (DIP-8) or TO-99 depending on the manufacturing variant.

   

Note: As this is an obsolete (vintage) component, original complete paper datasheets may require historical semiconductor archives (Telefunken Databook).
