HM338RLL-W
Photo Module for PCM Remote Control Systems
Description
The HM338RLL-W is a miniaturized receiver for use in Infrared carrier frequency PCM remote control systems. A high quality photo diode and a low noise preamplifier are assembled on lead frame, and 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 ● Suitable burst length ≥10 cycles/burst ● Low current consumption 0.35mA 3V ● Operates down to 2.2 Volt
Special Features
● Enhanced immunity against all kinds of disturbance light ● No occurrence of disturbance pulses at the output
● Lead-Free component in accordance with RoHS directives
Applications
TV, Set top box, DVD, AV equipments, Air Conditioner, and IR Remote Control system
