package 

• Internal filter for PCM frequency 

• Improved shielding against EMI 

• Supply voltage: 2.5 V to 5.5 V 

• Improved immunity against ambient light 

• Insensitive to supply voltage ripple and noise 

• Compliant to RoHS Directive 2002/95/EC and in

DESCRIPTION 

These products are miniaturized receivers for infrared 

remote control systems. A PIN diode and a preamplifier are 

assembled on a lead frame, the epoxy package acts as an 

IR filter. 

The demodulated output signal can be directly decoded by 

a microprocessor. The TSOP348.., TSOP322.. are 

compatible with all common IR remote control data formats. 

The TSOP324.., TSOP344.. are optimized to suppress 

almost all spurious pulses from energy saving fluorescent 

lamps but will also suppress some data signals. 

This component has not been qualified according to 

automotive specifications.

SUITABLE DATA FORMAT 

These products are designed to suppress spurious output 

pulses due to noise or disturbance signals. Data and 

disturbance signals can be distinguished by the devices 

according to carrier frequency, burst length and envelope 

duty cycle. The data signal should be close to the 

band-pass center frequency (e.g. 38 kHz) and fulfill the 

conditions in the table below. 

When a data signal is applied to the IR receiver in the 

presence of a disturbance signal, the sensitivity of the 

receiver is reduced to insure that no spurious pulses are 

present at the output. Some examples of disturbance 

signals which are suppressed are: 

• DC light (e.g. from tungsten bulb or sunlight) 

• Continuous signals at any frequency
