Vishay Semiconductors

MECHANICAL DATA

Pinning:

FEATURES

• Very low supply current

• Photo detector and preamplifier in one 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

• Component in accordance to RoHS 2002/95/EC and

WEEE 2002/96/EC

DESCRIPTION

The

TSOP322..,

TSOP324..

series

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 TSOP322.. is compatible with all

common IR remote control data formats. The TSOP324.. is

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.
