MECHANICAL DATA

Pinning for TSDP341.., TSDP343..:

FEATURES

• Very low supply current

• Continuous data rates up to 7777 bps

• Range up to 32 m

• Photo detector and preamplifier in one package

• Internal filter tuned to 38.4 kHz for 4800 bps or

57.6 kHz for 9600 bps

• Shielding against EMI

• Supply voltage: 2.5 V to 5.5 V

• Immunity against ambient light

• Insensitive to supply voltage ripple and noise

• Material categorization: for definitions of compliance

DESCRIPTION

These products are miniaturized receivers for low speed

infrared data transmission. A PIN diode and a preamplifier

are assembled on a lead frame, the epoxy package contains

an IR filter.

The demodulated output can be directly connected to a

UART or a microprocessor. The TSDP34138 may be used

for continuous reception of data according to RS-232 at

4800 bps in noise free environments. Higher data rate

RS-232 may require data monitoring of gain levels. Non

RS-232 codings may be used to achieve continuous

average data rates up to 7800 bps in noisy ambients.

This component has not been qualified according to

automotive specifications.
