Texas Instruments SN74AUP1T17 Single Schmitt-Trigger Buffer Gate
Texas Instruments SN74AUP1T17 Single Schmitt-Trigger Buffer Gate performs the Boolean function Y = A with designation for logic-level translation applications with output referenced to supply VCC. AUP technology is low-power logic technology designed to extend battery life in operating. All input levels accept 1.8V LVCMOS signals while operating from either a single 3.3V or 2.5V VCC supply. This product also maintains excellent signal integrity.
The wide VCC range of 2.3V to 3.6V allows the possibility of switching output levels to connect to external controllers or processors. Schmitt-trigger inputs (ΔVT = 210mV between negative and positive input transitions) offer improved noise immunity during switching transitions, especially useful on analog mixed-mode designs. Schmitt-trigger inputs reject input noise, allow for slow input signal transition, and ensure the integrity of output signals.
Ioff is a feature that allows for powered-down conditions (VCC = 0V) and is important in portable and mobile applications. When VCC = 0V, signals from 0V to 3.6V can be applied to the device's outputs and inputs. No damage occurs to the device under these conditions. The Texas Instruments SN74AUP1T17 is designed with an optimized current-drive capability of 4mA to reduce overshoot, undershoot, and line reflections caused by high-drive outputs.
