APPLICATIONS Wave and pulse shapers Astable multivibrators Monostable multivibrators. DESCRIPTION The 74AHC1G/AHCT1G14 is a high-speed Si-gate CMOS device. The 74AHC1G/AHCT1G14 provides the inverting buffer function with Schmitt-trigger action. These devices are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
TYPICAL SYMBOL tPHL/tPLH CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD × VCC2 × fi + (CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts. 2. The condition is VI = GND to VCC. FUNCTION TABLE See note 1. INPUT A L H Note 1. H = HIGH voltage level; L = LOW voltage level. OUTPUT Y H L PARAMETER propagation delay A to Y input capacitance power dissipation c……
