Product Overview
The XL-IRM638T-TR2 is a XINGLIGHT infrared remote receiver module categorized under LED components. It uses an SMD epoxy resin semi-circular spherical package with 5.0 x 4.0 x 4.0 mm dimensions and a general dimensional tolerance of ±0.25 mm unless otherwise specified.
Electrical operation is centered on a 37.9 kHz typical carrier or recommended input frequency. Recommended supply voltage is 2.7 V minimum to 5.5 V maximum, while the absolute maximum supply voltage is 6.0 V at Ta=25°C. At VDD=5 V and Ta=25°C, working current is specified as 0.4 mA minimum, 0.5 mA typical, and 0.7 mA maximum.
The receiver output is TTL and CMOS compatible with active-low logic. Output limits include 250 mV maximum low-level output voltage at Isink=2.0 mA and 4.5 V minimum to 5.0 V maximum high-level output voltage at VCC=5 V. Assembly limits include 260°C for up to 6 s wave soldering and 300°C for 3 s manual soldering.
