DESCRIPTION

The 74HC2G/HCT2G86 is a high-speed Si-gate CMOS

device.

The 74HC2G/HCT2G86 provides dual 2-input

exclusive-OR gate.

QUICK REFERENCE DATA

GND = 0 V; Tamb =25 °C; tr =tf ≤ 6.0 ns.

Notes

1. CPD is used to determine the dynamic power dissipation (PD in µW).

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 switching outputs;

∑ (CL × VCC2 × fo) = sum of outputs.

2. For 74HC2G86 the condition is VI = GND to VCC.

For 74HCT2G86 the condition is VI = GND to VCC − 1.5 V.
