The Vishay TSOP1236 is a miniaturized receiver for infrared remote control systems. Designed for applications requiring infrared remote control and data transmission, it operates at a carrier frequency of 36 kHz. The device integrates a photodiode, preamplifier, and an IR filter within a single epoxy package.

Applications

• Infrared remote control systems for televisions
• Infrared remote control systems for set-top boxes
• Infrared remote control systems for audio equipment
• Remote control for air conditioners
• Light barrier

Features

• Improved immunity against ambient light
• Low supply current
• Photo detector and preamplifier in one package
• Internal filter for PCM frequency
• TTL and CMOS compatibility
• Output active low
• Supply voltage: 2.5 V to 5.5 V
• Carrier frequency: 36 kHz
• Available in different packages

Benefits

• Enhanced performance in environments with high levels of ambient light.
• Reduced power consumption due to low supply current requirements.
• Simplified circuit design with integrated photodiode and preamplifier.
• Increased operational reliability from the internal PCM frequency filter.
• Simplified interfacing with digital control systems because of TTL and CMOS compatibility.

Additional Details

The TSOP1236 operates efficiently over a supply voltage range of 2.5 V to 5.5 V, making it adaptable to various power supply configurations. The epoxy package is engineered to provide effective IR signal filtering, ensuring that only signals at the designated 36 kHz carrier frequency are processed. The output of the TSOP1236 is active low, outputting a low signal when a valid infrared signal is detected.
