The TFDU4300-TT1 from Vishay Semiconductor Opto Division represents the next generation of IrDA Transceiver Modules, combining reliability with advanced functionality. These components feature integrated Schmitt trigger inputs for improved noise rejection and low current consumption (<1 A in shutdown mode). With typical transmission distances of 0.2m to 1.0m and data rates matching standard serial port speeds, they're widely adopted in point-of-sale systems, electronic toll collection, and building automation controls. The TFDU4300-TT1 series is particularly noted for its consistent performance across temperature variations and its compliance with international infrared communication standards.
