74HC1G14; 74HCT1G14
The 74HC1G/HCT1G14 is a high-speed Si-gate CMOS device. The 74HC1G/HCT1G14 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. The standard output currents are 12 compared to the 74HC/HCT14.
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; ∑ (CL × VCC2 × fo) = sum of outputs. 2. For HC1G the condition is VI = GND to VCC. For HCT1G the condition is VI = GND to VCC 1.5 V. FUNCTION TABLE See note 1. INPUT A L H Note 1. H = HIGH voltage level; L = LOW voltage level. 2002 May 15 2 OUTPUT Y H L PARAMETER……
