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.

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 SN74AUP1T57 is designed with optimized current-drive capability of 4 mA to reduce line reflections, overshoot, and undershoot caused by high-drive outputs.

NanoStar package technology is a major breakthrough in IC packaging concepts, using the die as the package.
