MM74HC14 Hex Inverting Schmitt Trigger February 2008 MM74HC14 Hex Inverting Schmitt Trigger Features General Description Typical propagation delay: 13ns The MM74HC14 utilizes advanced silicon-gate CMOS technology to achieve the low power dissipation and Wide power supply range: 2V6V high noise immunity of standard CMOS, as well as the Low quiescent current: 20A maximum (74HC Series) capability to drive 10 LS-TTL loads. Low input current: 1A maximum The 74HC logic family is functionally and pinout compat- Fanout of 10 LS-TTL loads ible with the standard 74LS logic family. All inputs are Typical hysteresis voltage: 0.9V at V = 4.5V CC protected from damage due to static discharge by inter- nal diode clamps to V and ground.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
