DESCRIPTION/ORDERING INFORMATION

The SN74AUP1T157 is a single 2-input multiplexer that selects data from two data inputs (A and B) under

control of a common data select input (C). The state of the common data select input determines the particular

register from which the data comes. The output (Y) presents the selected data in the true (non-inverted) form.

AUP technology is the industry's lowest-power logic technology designed for use in extending battery-life in

operating. All input levels that accept 1.8-V LVCMOS signals, while operating from either a single 3.3-V or 2.5-V

VCC supply. This product also maintains excellent signal integrity (see Figure 2 and Figure 3).

The wide VCC range of 2.3 V to 3.6 V allows the possibility of switching output level to connect to external

controllers or processors.

Schmitt-trigger inputs (ΔVT = 210 mV between positive and negative input transitions) offer improved noise

immunity during switching transitions, which is especially useful on analog mixed-mode designs. Schmitt-trigger

inputs reject input noise, ensure integrity of output signals, and allow for slow input signal transition.

Ioff is a feature that allows for powered-down conditions (VCC = 0 V) and is important in portable and mobile

applications. When VCC = 0 V, signals in the range from 0 V to 3.6 V can be applied to the inputs and outputs of

the device. No damage occurs to the device under these conditions.

The SN74AUP1T157 is designed with optimized current-drive capability of 4 mA to reduce line reflections,

overshoot, and undershoot caused by high-drive outputs.
