DESCRIPTION
The 74HC2G/HCT2G126 is a high-speed Si-gate CMOS
device.
The 74HC2G/HCT2G126 provides one non-inverting
buffer/line driver with 3-state output. The 3-state output is
controlled by the output enable input pin (OE). A LOW at
pin OE causes the output as assume a high-impedance
OFF-state.
The bus driver output currents are equal compared to the
74HC/HCT126.

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(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;
Σ(CL × VCC2 × fo) = sum of the outputs.
2. For the 74HC2G126 the condition is VI = GND to VCC.
For the 74HCT2G126 the condition is VI = GND to VCC 1.5 V.
