DESCRIPTION/ORDERING INFORMATION
The SN74AUP1T87 performs the Boolean function Y = A Å B with designation for logic-level translation
applications with output referenced to supply VCC.
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 1 and Figure 2).
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 SN74AUP1T87 is designed with optimized current-drive capability of 4 mA to reduce line reflections,
overshoot, and undershoot caused by high-drive outputs.
