HM338

www.DataSheet.co.kr GOOD TAKE HM338 Photo Module for PCM Remote Control Systems Description The HM338 is miniaturized receiver for use infrared carrier frequency PCM remote control systems. A photo PIN diode and a low noise preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses. Features Photo detector and Preamplifier in one package Internal filter for PCM frequency TTL and CMOS compatibility Output active low Wide supply voltage & low current dissipation Suitable burst length ≥10 cycles/burst Special Features Enhanced immunity against all kinds of disturbance light No occurrence of disturbance pulses at the output Applications TV, VTR, Acoustic Devices, Air Conditioner, Car Stereo Units, Computers, Interior controlling appliances, and all appliances that require remote controlling Block Diagram Datasheet pdf - http://www.DataSheet4U.net/ www.DataSheet.co.kr GOOD TAKE Application Circuit HM338 *) recommended to suppress power supply disturbance Absolute Maximum Ratings Tamb = 25 Parameter Supply Voltage Supply Current Output Voltage Storage Temperature Range Operating Temperature Range Power Consumption Soldering Temperature (Tamb t (Pin 3) (Pin 3) (Pin 1) Test Conditions Symbol Vs Is Vo Tstg Tamb ptot Tsd Value 6.0 5 6.0 -30…+105 -25…+85 5...
