INTEGRATED CIRCUITS DATA SHEET 74HC1G14; 74HCT1G14 Inverting Schmitt-triggers Product specication Supersedes data of 2001 Mar 02 2002 May 15 Philips Semiconductors Product specication Inverting Schmitt-triggers FEATURES Wide operating voltage range from 2.0 to 6.0 V Symmetrical output impedance High noise immunity Low power dissipation Balanced propagation delays Very small 5 pins package Applications – Wave and pulse shapers – Astable multivibrators – Monostable multivibrators Output capability: standard. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6.0 ns. DESCRIPTION 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……
