Quad buffer/line driver; 3-state
Rev. 04 — 12 August 2009
Product data sheet
1. General description
The 74AHC126; 74AHCT126 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard
No. 7-A.
The 74AHC126; 74AHCT126 provides 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-level at pin nOE causes the outputs to assume a high-impedance OFF-state.
The 74AHC126; 74AHCT126 is identical to the 74AHC125; 74AHCT125 but has active
HIGH output enable inputs.

CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(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;
N = number of inputs switching;
