Specified for operation from 2.5–5.5 V, with 0.35 mA supply current at 3.3 V, TSDP34138/56 and TSDP34338/56 are designed for low-speed data transmission and consist of photodiode and preamplifier assembled on lead frame. Epoxy package (6.0 x 6.9 x 5.6 mm) acts as IR band pass filter for use with 940 nm IR LEDs. Using ASK on-off modulated 38.4 or 57.6 kHz signals from emitter with 250 mW/sr irradiance, products achieve continuous data transmission up to 7.8 kbps over range of up to 35 m.
