FEATURES
• Output capability: bus driver
• ICC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT126 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).
They are specified in compliance with JEDEC standard no. 7A.
The HC/HCT126 are four non-inverting buffer/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.
The “126” is identical to the “125” but has active HIGH enable inputs.

Notes
1.
C
PD is used to determine the dynamic power dissipation (PD in 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 V
∑ (CL × VCC2 × fo) = sum of outputs
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC − 1.5 V
