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.
