COSMOSIC SEMICONDUCTOR CO.
FM MODULATOR - INFRARED TRANSMITTER
GENERAL DESCRIPTION The HS2K219 is high speed ic types are frequency modulator. fabricated withsilicon gate CMOS technology . 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 . FEATURE: Output frequency range 50khz ~ 15Mhz . Automatic power on/off function . Low voltage and low power consumption . High speed max(3v=10Mhz);(5v=15Mhz) Low power dissipation icc=4uA(max.)at ta=25 Wide operating voltage range vcc(opr)=2 ~ 5v RECOMMENDED OPERATING CONDITIONS: Supply voltage vcc 2.5v to 5v ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL Supply voltage range Vcc DC vcc/ground current Power dissipation Storage temperature Lead temperature 10sec Icc PD Tstg TL VALUE -0.5 ~ 7 +_50 180 (MFP) - 20 ~ 120 300 UNIT V mA mW
