ELM7Sx ,ELM7Sx B •¡ SERIES CMOS LOGIC IC GENERAL DESCRIPTION •EELM7Sxx,ELM7SxxB Series are CMOS ICs. They realize a high speed operation similar to LS-TTL with a lower power consumption by CMOS features. An inner circuit structure of 3-stages logic gates obtains wider noise immunity and constant output. •E ELM7S66,ELM7S66B are CMOS analog switches. They realize a high speed operation with a low power consumption by CMOS features. With a low on resistance and a high transmission rate, they realize a wider input voltage range. •¡ FEATURES SOT-25 (2.9•~ 1.6•~ 1.1mm) 5 - pin package •E Very small SOT-26 (2.9•~ 1.6•~ 1.1mm) 6 - pin package •E Same electrical characteristics as 74HC Series •E Power voltage range : 2.0 •` 6.0V •E Operation t [ ... ]
