Product data sheet
1. General description
The 74AUP2T1326 is a high-performance, dual supply, low-power, low-voltage, dual
buffer/line driver with output enable circuitry.
The 74AUP2T1326 is designed for logic-level translation and combines the functions of
the 74AUP1G32 and 74AUP2G126. The buffer/line driver is controlled by two output
enable inputs (1OE and 2OE). A logic LOW on input 1OE causes the output 2Y to assume
a high-impedance OFF-state, a logic LOW on 2OE causes the output 3Y to assume a
high-impedance OFF-state. The output 1Y is the result of a logic OR of the two output
enable inputs.
The output enable inputs (1OE and 2OE) are Schmitt trigger inputs, they switch at
different voltages for positive and negative-going signals. The difference between the
positive voltage VT+ and the negative voltage VT− is defined as the input hysteresis voltage
VH. The output enable inputs accept standard input signals and are capable of
transforming slowly changing input signals into sharply defined, jitter-free output signals
Both VCC(A) and VCC(B) can be supplied at any voltage between 1.1 V and 3.6 V making
the device suitable for interfacing between any of the low voltage nodes (1.2 V, 1.5 V,
1.8 V, 2.5 V and 3.3 V) with compatible input levels. Pins 1OE, 2OE and 1Y are referenced
to VCC(A) and pins A, 2Y and 3Y are referenced to VCC(B).
The device ensures low static and dynamic power consumption and is fully specified for
partial power down applications using IOFF. The IOFF circuitry disables the outputs,
preventing any damaging backflow current through the device when it is powered down.
