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 (VT = 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.
