equivalent Bipolar Shottky TTL.
The internal circuit is composed of 3 stages
including buffer output, which enables high noise
immunity and stable output.
This together with its schmitt trigger function
allows it to be used on line receivers with slow
rise/fall input segnals.
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)
