ELM ELM7S08B 2-input and gate Datasheet

CMOS LOGIC IC
ELM7S08B 2-input AND gate
■General description
ELM7S08B is CMOS 2-input AND gate IC. It realizes high speed operation similar to LS-TTL with lower
power consumption by CMOS features. The inner circuit structure of 3-stage logic gate obtains wider noise
immunity and constant output.
