DESCRIPTION
The 74HC1G/HCT1G125 is a high-speed Si-gate CMOS
device.
The 74HC1G/HCT1G125 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 HIGH at
pin OE causes the output as assume a high-impedance
OFF-state.
The bus driver output currents are equal compared to the
74HC/HCT125.
