The WIR2238S is a high-speed frequency modulator chip, fabricated with silicon-gate CMOS
It achieves the high-speed operation similar to equivalent LSTTL while maintaining the CMOS
low power dissipation. All inputs are equipped with protection circuits against static discharge or
transient excess voltage.
For music, sound, or signal transmit by IR emitter build in audio device of (LCD) TV, Monitor,
