74AUP2G126
Low-power dual buffer/line driver; 3-state
Rev. 9 — 11 February 2013
Product data sheet
1. General description
The 74AUP2G126 provides the dual non-inverting buffer/line driver with 3-state output.
The 3-state output is controlled by the output enable input (nOE). A LOW level at pin nOE
causes the output to assume a high-impedance OFF-state. This device has the
input-disable feature, which allows floating input signals. The inputs are disabled when the
output enable input nOE is LOW.
Schmitt trigger action at all inputs makes the circuit tolerant to slower input rise and fall
times across the entire VCC range from 0.8 V to 3.6 V. This device ensures a very low
static and dynamic power consumption across the entire VCC range from 0.8 V to 3.6 V.
This device is fully specified for partial power-down applications using IOFF. The IOFF
circuitry disables the output, preventing a damaging backflow current through the device
when it is powered down.
2. Features and benefits

[3] ten is the same as tPZH and tPZL.
[4] tdis is the same as tPHZ and tPLZ.
[5] CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi N + (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;
(CL VCC2 fo) = sum of the outputs.
