DESCRIPTION
The 74LX 1G14 is a low voltag e CMOS SING LE SCHMITT INVERTER f abricated with sub-micron silicon gate and double -layer metal wiring C technology. It is ideal f or 1.65 to 5.5 V power and low noise applications. The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and stable output. Powerdownprotectionisprovidedoninputand output and 0 to 7V can be accepted on inputs with

no regard to the supply voltage. It c an be interfaced t o 5V signal environment for inputs in mixed 3.3/5V system. Pin configuration and func tion are the same as those of the 74LX1G04 but the 74LX1G14 has hysteresis. This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals. The input is equipped with protection circuits against static discharge, giving it ESD immunity and transient excess voltage.
