MAX4638 - Low-Voltage Analog Multiplexers

General Description

The MAX4638/MAX4639 are single 8:1 and dual 4:1 CMOS analog multiplexers/demultiplexers (muxes/ demuxes).

Each mux operates from a single +1.8V to +5V supply or dual ±2.5V supplies.

Key Features

  • Guaranteed RON 3.5Ω (+5V or ±2.5V Supplies) 6Ω (+3V Supply).
  • Guaranteed 0.4Ω RON Match Between Channels.
  • Guaranteed 1Ω RON Flatness Over Signal Range.
  • Guaranteed Low Leakage Currents 0.25nA at +25°C.
  • Switching Times: tON = 18ns, tOFF = 7ns.
  • +1.8V to +5.5V Single-Supply Operation ±2.5V Dual-Supply Operation.
  • Rail-to-Rail Signal Handling.
  • TTL/CMOS-Logic Compatible.
  • Crosstalk: -80dB (1MHz).
  • Off-Isolation: -60.

MAX4638/MAX4639 3.5Ω, Single 8:1 and Dual 4:1, Low-Voltage Analog Multiplexers General Description The MAX4638/MAX4639 are single 8:1 and dual 4:1 CMOS analog multiplexers/demultiplexers (muxes/ demuxes). Each mux operates from a single +1.8V to +5V supply or dual ±2.5V supplies. These devices feature 3.5Ω on-resistance (RON) when powered with a single +5V supply and have -75dB off-isolation and -85dB crosstalk from the output to each off channel. The switching times are 18ns tON and 7ns tOFF. They feature a -3dB 85MHz bandwidth and a guaranteed 0.25nA leakage current at +25°C. A +1.8V to +5.5V operating range makes the MAX4638/ MAX4639 ideal for battery-powered, portable instruments. All channels guarantee break-before-make switching.
