MAX321CUA中文资料美信数据手册PDF规格书

General Description

The MAX320/MAX321/MAX322 are precision, dual, SPST analog switches designed to operate from ±3V to ±8V dual supplies. The MAX320 has two normally open (NO) switches and the MAX321 has two normally closed (NC) switches. The MAX322 has one NO and one NC switch. Low power consumption (1.25mW) makes these parts ideal for battery-powered equip ment. They offer low leakage currents (100pA max) and fast switching speeds (tON = 150ns max, tOFF = 100ns max).
