DESCRIPTION/ORDERING INFORMATION

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

backed-up equipment. The SN74AUP1T57 is designed for logic-level translation applications with input switching

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

The wide VCC range of 2.3 V to 3.6 V allows the possibility of battery voltage drop during system operation and

ensures normal operation between this range.

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.

The SN74AUP1T57 can be easily configured to perform a required gate function by connecting A, B, and C

inputs to VCC or ground (see Function Selection table). Up to nine commonly used logic gate functions can be

performed.
