FM-9038TM2-5AN-LS5.0
IR Receiver Modules for Remote Control Systems
Description
The FM-9038TM2-5AN-LS5.0 is remote control receiver modules.
Pin diode and receiver IC are assembled on one module.
Small-sized, light-weight, and low current consumption.
modules have been achieved by using resin mold.
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
Supply Voltage Range: 2.7V to 6.5V
TTL and CMOS compatibility
Photo detector and preamplifier in one package.
Internal filter for PCM frequency
Open collector output (built-in Pull-up resistor(40K)
Output active low
Enhanced Immunity against all kinds of disturbance light
No occurrence of disturbance pulses at output pin within nominal conditions.
Short settling time after power On.( below 1msec)
Meet RoHS
