THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 IR Receiver Modules for Data Transmission MECHANICAL DATA Pinning for TSDP341.., TSDP343..: 1 = OUT, 2 = GND, 3 = VS 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 please see www.vishay.com/doc?99912 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.
