wiring C2MOS technology. It is ideal for low
power applications mantaining high speed
operation similar to equivalent Bipolar Schottky
TTL.
The internal circuit is composed of 3 stages
including buffer output, which enables high noise
immunity and stable output.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to
Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD VCC fIN + ICC/n (per circuit)
