DESCRIPTION The 74LCX14 is a low voltage CMOS HEX SCHMITT INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications. It can be interfaced to 5V signal environment for inputs PIN CONNECTION AND IEC LOGIC SYMBOLS
It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption. Pin configuration and function are the same as those of the 74LCX04 but the 74LCX14 has hysteresis between the positive and negative input threshold typically of 0.8V. 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 = 500 or equivalent RT = ZOUT of pulse generator (typically 50)
