DESCRIPTION The 74AC14 is an advanced high-speed CMOS HEX SCHMITT TRIGGER INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. 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 signals. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

CIN CPD
Input Capacitance Power Dissipation Capacitance (note 1)
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 x VCC x fIN + ICC/6 (per gate)
TEST CIRCUIT
CL = 50pF or equivalent (includes jig and probe capacitance) RL = R1 = 500 or equivalent RT = ZOUT of pulse generator (typically 50)
