Input Voltage Range

The guaranteed input voltage range is ±2.5V. Exceeding

this value can cause unpredictable results, including out-

put clipping, excessive input current, and switching

delays.

Multiplexer

The input multiplexer (mux) is controlled by TTL/CMOS-

compatible address inputs (see

Truth Tables.) There is

no internal memory except the address latch (LE) on

the MAX4159/MAX4259. If power is first applied with

the latch enabled, IN0 is selected.

Input capacitance is a constant, low 2pF for either input

channel, regardless of whether or not the channel is

selected.

All logic levels (EN, LE, and A0) default low if left open-

circuit.
