74HC1G/74HC2G 系列，NXP高速 CMOS 逻辑 工作电压 2.0 － 6.0 兼容性：输入 CMOS、输出 CMOS ### 74HC 系列
General description
The 74HC1G126 and 74HCT1G126 are high-speed, Si-gate CMOS devices. They provide 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 HC device has CMOS input switching levels and supply voltage range 2 V to 6 V.
The HCT device has TTL input switching levels and supply voltage range 4.5 V to 5.5 V.
The bus driver output currents are equal to those of the 74HC126 and 74HCT126.
Features
