The HP 44713A is a 24-channel high-speed FET multiplexer that directly multiplexes voltage, resistance, thermocouples, and strain gages. The 44713A maximizes measurement throughput and increases system reliability.

• Maximum switch rates: 5500 channels/second from back-plane, 100000 channels/second from ribbon cable
• Up to six (eight with extender) high-speed FET multiplexers can be controlled through the ribbon cable
• The 24-channel multiplexers switch high and low only. Each floating input is balanced (equal impedance between high-to-chassis and low-to-chassis) to provide good common mode rejection
• FETs have no mechanical limitations, as there is no wearing out due to switching 
• Maximum input voltage: Rear and back-plane input protected to 16 V peak. With analog back-plane disconnected from multiplexer, the back-plane voltage can go up to 42 V peak
• Maximum input current: 1 mA per channel
• Input impedance
  • Power on resistance: >10⁸ Ω
  • Power off resistance with Vin 10 V: >1000 Ω
  • Power off resistance with Vin >10 V: >200 Ω
  • Maximum capacitance at 1 MHz: 200 pF
• Closed channel path resistance: 3.1 kΩ
• Bandwidth: 1.0% flatness at 20 kHz, -3 dB bandwidth at 200 kHz
• Crosstalk: -50 dB at 10 kHz, -35 dB at 100 kHz
• Maximum offset voltage: 15 µV at 0 to 28° C, 185 µV at 28 to 55° C
• Maximum bias current
  • Current sourced by High or Low to Chassis into Input Terminals or back-plane, with isolation relays closed: ±5 nA DC at 0 to 28° C, ±45 nA DC at 28 to 55° C
  • Current sourced by High or Low to Chassis into back-plane, with isolation relays open: ±1 nA DC at 0 to 55° C
• Maximum wire size: 16 AWG
• Reference junction compensation accuracy: 0.1° C
• Maximum temperature difference across isothermal module: 0.2° C
