2 Description

AUP technology is the industry's lowest-power logic

technology designed for use in battery-operated or

battery backed-up equipment. The SN74AUP1T97 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 SN74AUP1T97 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 SN74AUP1T97 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.
