TSOP344..SS1BS12
Vishay Semiconductors
IR Receiver Modules for Remote Control Systems
Description
The TSOP344..SS1BS12 - 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

is a standard IR remote control receiver series for 3 V
16672
supply voltage, with excellent suppression of distur-
bance signals.
Features
• Photo detector and preamplifier in one
package
• Internal filter for PCM frequency
e3
• Improved shielding against electrical
field
disturbance
• TTL and CMOS compatibility
• Output active low
• Supply voltage: 2.7 V to 5.5 V
• Improved immunity against ambient light
