DESCRIPTION
The AC14 is an advanced high-speed CMOS
HEX INVERTER fabricated with sub-micron
silicon gate and double-layer metal wiring C2MOS
technology. It is ideal for low power applications
mantaining high speed operation similar to

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)

RL = R1 = 500or equivalent
RT = ZOUT of pulse generator (typically 50)
