MC100EPT21DR2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MC100EPT21DR2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。

3.3V Differential LVPECL/LVDS/CML to LVTTL/LVCMOS Translator

The MC100EPT21 is a Differential LVPECL/LVDS/CML to LVTTL/LVCMOS translator. Because LVPECL (Positive ECL), LVDS, and positive CML input levels and LVTTL/LVCMOS output levels are used, only +3.3 V and ground are required. The small outline 8?lead SOIC package makes the EPT21 ideal for applications which require the translation of a clock or data signal.

The VBB output allows this EPT21 to be cap coupled in either single?ended or differential input mode. When single?ended cap coupled, VBB output is tied to the D input and D is driven for a non?inverting buffer, or VBB output is tied to the D input and D is driven for an inverting buffer. When cap coupled differentially, VBB output is connected through a resistor to each input pin. If used, the VBB pin should be bypassed to VCC via a 0.01 μF capacitor. For additional information see AND8020/D. For a single?ended direct connection use an external voltage reference source such as a resistor divider. Do not use VBB for a single?ended direct connection or port to another device.
