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.

tpd is the same as tPLH and tPHL. ten is the same as tPZL and tPZH. tdis is the same as tPLZ and tPHZ. CPD is used to determine the dynamic power dissipation PD (µW). PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where: fi = input frequency in MHz fo = output frequency in MHz CL = output load capacitance in pF VCC = supply voltage in Volts ∑ (CL × VCC2 × fo) = sum of outputs
