MAX4598 19-1385 Rev 0 10/98 Low-Voltage, Combination Single-Ended 8-to-1/Differential 4-to-1 Multiplexer General Description Features The MAX4598 low-voltage, CMOS analog IC is a con- V+ and GND Can Be Switched to the Output figurable single-ended 8-to-1/differential 4-to-1 multi- Channels plexer. In addition to the input channels, both V+ and 75 (max) On-Resistance GND can be switched to the output channels, enabling the supply voltages to be monitored. The MAX4598 Single-Ended or Differential Operation operates from a single +2.7V to +12V supply or from 2pC (typ) Charge Injection dual 6V supplies. The device has low on-resistance (75 max) and TTL-compatible logic inputs from either Latched or Unlatched Operation 5V or a single +5V supply. Each switch can handle TTL-Compatible Logic Inputs at 5V Supply Rail-to-Rail analog signals. The MAX4598 has two modes of operation: as a standard multiplexer and as a Handles Rail-to-Rail Analog Signals latchable multiplexer where the address lines are strobed. The off-leakage current is only 0.1nA at T = A +25C and 2nA at T = +85C. ESD protection is > 2kV A Ordering Information per Method 3015.7. The MAX4598 is available in small 20-pin SSOP, SO, PART TEMP. RANGE PIN-PACKAGE and DIP packages.

Limit forward cur- rent to maximum current ratings 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.
