74HC3G14 HCT3G14 Triple inverting Schmitt trigger Rev. 6 1 February 2019 Product data sheet 1. General description The 74HC3G14 74HCT3G14 is a triple inverter with Schmitt-trigger inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free CC output signals. 2. Features and benefits Wide supply voltage range from 2.0 V to 6.0 V Complies with JEDEC standard no. 7A Input levels: For 74HC3G14: CMOS level For 74HCT3G14: TTL level High noise immunity Low power dissipation Balanced propagation delays Unlimited input rise and fall times Multiple package options ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V Specified from -40 C to +85 C and -40 C to +125 C 3. Applications Wave and pulse shaper for highly noisy environments Astable multivibrators Monostable multivibrators 4. Ordering information Table 1.
