INTEGRATED CIRCUITS DATA SHEET 74HC2G32; 74HCT2G32 Dual 2-input OR gate Product specication Supersedes data of 2002 Jul 17 2003 Oct 30 Philips Semiconductors Product specication Dual 2-input OR 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 8 pins package Output capability: standard ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf ≤ 6.0 ns. DESCRIPTION 74HC2G32; 74HCT2G32 The 74HC2G/HCT2G32 is a high-speed Si-gate CMOS device. The 74HC2G/HCT2G32 provides the dual 2-input OR function. TYPICAL SYMBOL tPHL/tPLH CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD × VCC2 × fi × N + ∑ (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; N = total load switching outputs; ∑ (CL × VCC2 × fo) = sum of outputs. 2. For 74HC2G32: the condition is VI = GND to VCC. For 74HCT2G32: the condition is VI = GND to VCC 1.5 V.
