MAX381/MAX383/MAX385 19-0300 Rev 0 9/94 Precision, Low-Voltage Analog Switches General Description Features The MAX381/MAX383/MAX385 are precision, low-volt- Single-Supply Operation (+3V to +15V) age analog switches. The single-pole single-throw Bipolar-Supply Operation (3V to 8V) MAX381 and double-pole single-throw MAX385 dual Pin-Compatible with DG401/DG403/DG405 switches are normally open. The single-pole double- Low On-Resistance, 20 Typical (35 Max) throw MAX383 has two normally open and two normally closed poles. All three parts offer low on-resistance Guaranteed Matched On-Resistance Between (less than 35), guaranteed to match to within 2 Channels, <2 between channels and to remain flat over the specified Guaranteed Flat On-Resistance over Specified analog signal range (4 max). They also offer low leak- Analog Signal Range, <4 age (less than 250pA at +25C and less than 2.5nA at Guaranteed Charge Injection, <5pC +85C) and fast switching (turn-on time less than 175ns and turn-off time less than 100ns). Guaranteed Off-Channel Leakage, <2.5nA at +85C The MAX381/MAX383/MAX385 are fabricated with TTL/CMOS-Logic Compatible with 3V, 5V, 3V, Maxims low-voltage silicon-gate process for high sys- and 5V Supplies tem accuracy. Design improvements guarantee Rail-to-Rail Analog Signal Handling Capability extremely low charge injection (<5pC) and low power consumption (<10W).

Limit forward diode current to maximum current rating. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
