74AUP1T97屬于集成電路（IC）的轉(zhuǎn)換器電平移位器。由安森美半導(dǎo)體公司制造生產(chǎn)的74AUP1T97轉(zhuǎn)換器，電平移位器邏輯轉(zhuǎn)換器或電平移位器 IC 可用于在數(shù)字邏輯設(shè)備之間傳遞信息，這些設(shè)備可在不同/不兼容的供電電壓下工作，或可實(shí)現(xiàn)不同的信令方式。例如，可以將需要 5 V 電源的數(shù)字輸出傳感器連接到具有 3.3 V I/O 電源的 FPGA，或者在 CMOS 或 TTL 等單端信令方式與 PECL 或 LVDS 等差分技術(shù)之間進(jìn)行轉(zhuǎn)換。

描述 Description

The 74AUP1T97 is a universal configurable 2?input logic gate that

provides single supply voltage level translation. This device is

designed for applications with inputs switching levels that accept

1.8 V low voltage CMOS signals while operating from either a single

2.5 V or 3.3 V supply voltage. The 74AUP1T97 is an ideal low power

solution for mixed voltage signal applications especially for

battery?powered portable applications. This product guarantees very

low static and dynamic power consumption across entire voltage

range. All inputs are implemented with hysteresis to allow for slower

transition input signals and better switching noise immunity.

The 74AUP1T97 provides for multiple functions as determined by

various configurations of the three inputs. The potential logic

functions provided are MUX, AND, NAND, OR, and NOR, inverter

and buffer. Refer to Figures 3 to 9.
