IR Receiver Modules for Remote Control Systems
Description
The TSOP348..VI1 - series are miniaturized receivers
for infrared remote control systems. PIN diode and
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. TSOP348..VI1 is the
standard IR remote control receiver series for 3 V
supply voltage, supporting all major transmission
codes.
Features
• Photo detector and preamplifier in one package
• Internal filter for PCM frequency
• Improved shielding against electrical field
disturbance
• TTL and CMOS compatibility
• Output active low
• Supply voltage range: 2.7 V to 5.5 V
• Improved immunity against ambient light
