INTEGRATED CIRCUITS DATA SHEET 74HC1G08; 74HCT1G08 2-input AND gate Product specication Supersedes data of 2001 Mar 02 2002 May 17 Philips Semiconductors Product specication 2-input AND gate FEATURES Wide supply 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 Output capability: standard. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf ≤ 6.0 ns. DESCRIPTION 74HC1G08; 74HCT1G08 The 74HC1G/HCT1G08 is a high-speed Si-gate CMOS device. The 74HC1G/HCT1G08 provides the 2-input AND function. The standard output currents are 12 compared to the 74HC/HCT08. 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. INPUTS A L L H H Note 1. H = HIGH voltage level; L = LOW voltage level.
