这个MAX4638 / MAX4639是单身8:1和双4:1 CMOS模拟多路复用器/ demultiplexers(muxes / demuxes)。 每个mux运营一个+ 1.8 V + 5 V电源或双±2.5 V供应。这些设备特性3.5Ωon-resistance(RON)当由一个单一+ 5 V供应和有-75分贝off-isolation和-85分贝相声从输出到每个了通道。 切换时间18 ns吨和7 ns纨绔子弟。它们具有一个3分贝85 MHz频带和保证0.25钠泄漏电流在+ 25°C。

一个+ 1.8 V + 5.5 V操作范围使MAX4638 / MAX4639理想的电池供电的便携式仪器。所有渠道保证break-before-make切换。 这些部件特性双向操作,可以处理轨到轨模拟信号。所有的控制输入TTL / CMOS-logic兼容。BCD译码在标准格式,一个使输入是级联的设备提供简化。这些设备都可以在小16-pin QFN薄,TSSOP,所以包,以及一个20-pin薄QFN包。The MAX4638/MAX4639 are single 8:1 and dual 4:1 CMOS analog multiplexers/demultiplexers (muxes/demuxes). Each mux operates from a single +1.8V to +5V supply or dual ±2.5V supplies. These devices feature 3.5Ω on-resistance (R_ON) when powered with a single +5V supply and have -75dB off-isolation and -85dB crosstalk from the output to each off channel. The switching times are 18ns t_ON and 7ns t_OFF. They feature a -3dB 85MHz bandwidth and a guaranteed 0.25nA leakage current at +25°C.

A +1.8V to +5.5V operating range makes the MAX4638/MAX4639 ideal for battery-powered, portable instruments. All channels guarantee break-before-make switching. These parts feature bidirectional operation and can handle rail-to-rail analog signals. All control inputs are TTL/CMOS-logic compatible. Decoding is in standard BCD format, and an enable input is provided to simplify cascading of devices. These devices are available in small 16-pin thin QFN, TSSOP, and SO packages, as well as a 20-pin thin QFN package.
