Quad buffer/line driver (3-State)
Product specification
74LV126
FEATURES
• Wide operating voltage: 1.0 to 5.5 V
• Optimized for low voltage applications: 1.0 to 3.6 V
• Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V
• Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V,
Tamb = 25°C
• Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V,
Tamb = 25°C
• Output capability: bus driver
• ICC category: MSI
DESCRIPTION
The 74LV126 is a low-voltage Si-gate CMOS device that is pin and
function compatible with 74HC/HCT126.
The 74LV126 consists of four non-inverting buffers/line drivers with
3-state outputs. The 3-state outputs (nY) are controlled by the output
enable input (nOE). A LOW at nOE causes the outputs to assume a
high impedance OFF-state.

NOTE:
1. CPD is used to determine the dynamic power dissipation (PD in µW)
PD = CPD × VCC2 × fi )ȍ (CL × VCC2 × fo) where:
fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
ȍ (CL × VCC2 × fo) = sum of the outputs.
