MAX4534CUD+

The MAX4534CUD+ is a fault protected, high voltage, single 4 to 1 multiplexer in 14 pin TSSOP package. This multiplexer has fault protected inputs, rail to rail signal handling capability and overvoltage clamping at 150mV beyond the rails. The MAX4534 includes ±40V overvoltage protection with supplies off and ±25V protection with supplies ±15V supplies. The device has maximum on-resistance of 950 ohm and is matched between channels to 25ohm maximum at TA = +25°C with single +12V supply. All digital inputs have TTL logic thresholds ensuring TTL/CMOS logic compatibility when using a single +12V or dual ±15V supplies. It is typically used in data acquisition systems and redundant/backup systems.

• Supply voltage range from 9V to 36V, ± 4.5V to ± 20V
• Operating temperature range from 0°C to 70°C
• Power supply sequencing is not required
• All channels off with power off
• Output clamped to appropriate supply voltage during fault condition
• 1Kohm typical output clamp resistance during overvoltage
• Fault response time of 20ns and break before make time delay of 100ns with single +12V supply
• COM Off leakage current of 2nA & COM on-leakage current of 2nA at TA = 25°C with single +12V supply
• 2pC charge injection, -62dB off isolation & -65dB crosstalk at TA = 25°C with single +12V supply
