U74LVX4051 CMOS IC
8-CHANNEL ANALOG MULTIPLEXER/DEMULTIPLEXER
DESCRIPTION
FEATURES
U74LVX4051 CMOS IC
8-CHANNEL ANALOG MULTIPLEXER/DEMULTIPLEXER
DESCRIPTION
The U74LVX4051 is a high speed , low-voltage drive analog multiplexer/demultiplexer using silicon gate CMOS technology. In 3V
and 5V systems these can achieve high-speed operation with the low power dissipation that is a feature of CMOS.
The U74LVX4051 offer analog/digital signal selection as well as mixed signals. The 4051 has an 8-Channel configuration.
The switchses for each channel are turned on by the control pin digital signals.
Although the control signal logical amplitude (VCC-GND) is small,the device can perform large-amplitude (VCC-VEE) signal switching.
For example, if VCC=3V, GND=0V and VEE=-3V, signals between -3V and +3V can be switched from the logical circuit using a signal 3V power supply.
All input pins are equipped with a newly developed input protection circuit that avoids the need for a diode on the plus side (forword side from the input to the VCC). As a result, for example, 5V signals can be permitted on the inputs even when the power supply voltage to the circuits is off. As a result of this input power protection, the U74LVX4051 can be used in a variety of applications, including in the system which has two power supplies, and in battery bachup circuits.

U74LVX4051 CMOS 積體電路
8 通道類比多工器/解多工器
產品描述
U74LVX4051 為高速度、低電壓驅動的類比多工/解多工器，採用矽閘 CMOS 技術製造。在 3V 和 5V 系統中，能達成高速操作並具備 CMOS 的低功耗特性。
U74LVX4051 支援類比與數位訊號選擇，也可處理混合訊號。4051 為 8 通道配置。各通道的開關由控制腳位的數位訊號啟動。
雖然控制訊號的邏輯振幅（VCC-GND）較小，裝置仍可進行大振幅訊號（VCC-VEE）切換。例如，當 VCC=3V、GND=0V、VEE=-3V 時，邏輯電路可使用 3V 電源切換 -3V 至 +3V 之間的訊號。
所有輸入端皆內建新型輸入保護電路，無需輸入至 VCC 方向的保護二極體。因此，即使主電源未供電，仍可接受來自 5V 訊號的輸入。此電源保護設計使 U74LVX4051 適用於雙電源系統與電池備援電路等多種應用。
產品特性
- 低導通電阻：
- RON = 22Ω（典型值，VCC-VEE = 3V）

- 低功耗：ICC = 4μA（最大值，TA = 25°C）
- 輸入電平：
- VIL = 0.8V（最大，VCC = 3V）
- VIH = 2.0V（最小，VCC = 3V）
- 所有控制輸入皆具備電源關閉保護功能
- 腳位與功能相容於 U74HC4051
