描述 Description

The NLSV4T240E is a 4-bit configurable dual-supply voltage level translator. The input An and output Bn ports are designed to track two different power supply rails, VCCA and VCCB respectively. Both supply rails are configurable from 0.9 V to 4.5 V allowing universal low-voltage translation from the input An to the output Bn port. The NLSV4T240E is similar to the NLSV4T240; however, it has enhanced power-off characteristics.

特性 Features

? Wide VCCA and VCCB Operating Range: 0.9 V to 4.5 V

? Inputs and Outputs have OVT Protection to 4.5 V
? Nonpreferential VCCA and VCCB Sequencing
? Outputs at 3State until Active VCC is Reached
? PowerOff Protection
? Outputs Switch to 3State with VCCB at GND
? UltraSmall Packaging: 1.7 mm x 2.0 mm UQFN12
? This is a PbFree Device

應(yīng)用 Application

? Mobile Phones, PDAs, Other Portable Devices

簡介

NLSV4T240E屬于集成電路（IC）的轉(zhuǎn)換器電平移位器。由制造生產(chǎn)的NLSV4T240E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。
