MECHANICAL DATA

Pinning:

FEATURES

• Continuous data transmission possible

• Very low supply current

• Photo detector and preamplifier in one package

• Internal filter for PCM frequency

• Supply voltage: 2.5 V to 5.5 V

• Improved immunity against ambient light

• Capable of side or top view

• Insensitive to supply voltage ripple and noise

• Two lenses for high sensitivity and wide receiving angle

• Narrow optical filter to reduce interference from plasma

TV emissions

• Material categorization: For definitions of compliance

DESCRIPTION

The TSSP77P38 series are two lens miniaturized receivers

for Mid range proximity sensor systems. A PIN diode and a

preamplifier are assembled on a lead frame, the epoxy

package acts as an IR filter.

The output pulse width of the TSSP77P38 has an almost

linear relationship to the distance of the emitter or the

distance of an reflecting object. The TSSP77P38 is

optimized to suppress almost all spurious pulses from

energy saving fluorescent lamps.

This component has not been qualified according to

automotive specifications
