What the 74HC14 does
The 74HC14/74HCT14 is a hex inverting Schmitt trigger available in SO14, TSSOP14, and DHVQFN14 packages across commercial, industrial, and military temperature ranges. It operates on a 2.0 to 6.0 V supply, features high noise immunity, and supports unlimited input rise and fall times. This component is typically used for wave and pulse shaping, as well as in astable and monostable multivibrator circuits. The device includes clamp diodes to interface inputs to voltages exceeding VCC and transforms slowly changing signals into sharply defined, jitter-free outputs.
