Ultra Small Profile Package IrDA® Data Compliant Low Power 115.2 kbit/s Infrared Transceiver

HP => Agilent Technologies 

CAUTIONS: The BiCMOS inherent to the design of this component increases the component’s

susceptibility to damage from the electrostatic discharge (ESD). It is advised that normal static

precautions be taken in handling and assembly of this component to prevent damage and/or degradation

which may be induced by ESD.

Note:

11. An in-band optical signal is a pulse/sequence where the peak wavelength, λp, is defined as 850 ≤ λp ≤ 900 nm, and the pulse characteristics

are compliant with the IrDA Serial Infrared Physical Layer Link Specification v1.4.
