MC14504B集成電路（IC）的轉(zhuǎn)換器電平移位器規(guī)格書PDF中文資料

MC14504B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MC14504B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)之間進行轉(zhuǎn)換。

The MC14504B is a hex non?inverting level shifter using CMOS technology. The level shifter will shift a TTL signal to CMOS logic levels for any CMOS supply voltage between 5 and 15 volts. A control input also allows interface from CMOS to CMOS at one logic level to another logic level: Either up or down level translating is accomplished by selection of power supply levels VDD and VCC. The VCC level sets the input signal levels while VDD selects the output voltage levels.
