描述：TP8485E-SR
TP8485E-SR是3V〜5.5V供電的收發(fā)器符合RS-485和RS-422平衡標(biāo)準(zhǔn)通訊。驅(qū)動器輸出和接收器輸入為防止±18kV ESD沖擊而不會閂鎖。該系列的變送器具有出色的差分性能輸出電壓（最小2.5V / 5Vcc），需要輸入RS-48554Ω負(fù)載，以獲得更好的抗噪性，或允許多達(dá)8個“星形”拓?fù)渲械?20Ω終端。這些設(shè)備總線電流非常低，因此它們呈現(xiàn)出真正的“ 1/8單位”加載”到RS-485總線。最多允許256個無需使用中繼器的網(wǎng)絡(luò)上的收發(fā)器。接收器（Rx）輸入具有“完全故障保護(hù)”設(shè)計(jì)，如果Rx輸入為浮動，短路或在終止但未驅(qū)動的總線上。接收輸出具有高驅(qū)動電平-VOL時通常為25mA= 1V（以簡化光耦隔離設(shè)計(jì)接口）。
TP8485E-SR提供SOIC-8和MSOP-8封裝封裝，溫度范圍為–40°C至125°C。
