CD4504BM屬于集成電路（IC）的轉(zhuǎn)換器電平移位器。由美國德州儀器公司制造生產(chǎn)的CD4504BM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。

Features:

? Independence of power-supply sequence

considerations-Vec can exceed Voo;

input signals can exceed both Vcc and Voo

? Up and down level-shifting capability

= Shiftable input threshold for either

CMOS or TTL compatibility

= Standardized symmetrical output

characteristics

= 100% tested for quiescent current @ 20 V

? Maximum input current of 1 uA at 18 V

over full package-temperature range;

100 nA at 18 V and 25°C

= 5V,10V, and 15 V parametric ratings

? Moats all requirements of JEDEC
