DESCRIPTION
MECHANICAL DATA
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.
Pinning for TSOP341.., TSOP343.., TSOP345..:
1 = OUT, 2 = GND, 3 = VS
Pinning for TSOP321.., TSOP323.., TSOP325..:
1 = OUT, 2 = VS, 3 = GND
The demodulated output signal can be directly decoded
by a microprocessor. The TSOP321.., TSOP341.. are
compatible with all common IR remote control data formats.
The TSOP323.., TSOP343.. are optimized to better
suppress spurious pulses from energy saving fluorescent
lamps. The TSOP325.., TSOP345.. have an excellent noise
suppression. It is immune to dimmed LCD backlighting and
any fluorescent lamps. AGC3 and AGC5 may also suppress
some data signals in case of continuous transmission.
Please see the document “Product Transition Schedule” at
www.vishay.com/ir-receiver-modules/ for up-to-date info,
when this product will be released.
This component has not been qualified according to
automotive specifications.
