74HC1G126; 74HCT1G126
Bus buffer/line driver; 3-state
Rev. 04 — 20 July 2007
Product data sheet
1. 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.
