74VCX163245集成電路（IC）的轉(zhuǎn)換器電平移位器規(guī)格書PDF中文資料

74VCX163245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74VCX163245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。

General Description

The VCX163245 is a dual supply, 16-bit translating transceiver that is designed for 2 way asynchronous communication between busses at different supply voltages by providing true signal translation. The supply rails consist of VCCA, which is a higher potential rail operating at 2.3V to 3.6V and VCCB, which is the lower potential rail operating at 1.65V to 2.7V. (VCCB must be less than or equal to VCCA for proper device operation). This dual supply design allows for translation from 1.8V to 2.5V busses to busses at a higher potential, up to 3.3V.
