74HC1G126; 74HCT1G126

Bus buffer/line driver; 3-state

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 and benefits

  • Symmetrical output impedance
  • High noise immunity
  • Low power dissipation
  • Balanced propagation delays
  • SOT353-1 and SOT753 package options
