74HCT4351D

8-channel analog multiplexer/demultiplexer with latch

The 74HC4351; 74HCT4351 is a single-pole octal-throw analog switch (SP8T) suitable for use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch features three digital select inputs (S0 to S2), eight independent inputs/outputs (Yn), a common input/output (Z) and two digital enable inputs (E1 and E2). With E1 LOW and E2 HIGH, one of the eight switches is selected (low impedance ON-state) by S0 to S2. The data at the select inputs may be latched by using the latch enable input (LE). When LE is HIGH the latch is transparent. When E1 is HIGH or E2 is LOW all 8 analog switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features and benefits

  • Wide analog input voltage range from -5 V to +5 V

  • Complies with JEDEC standard no. 7A

  • Low ON resistance:

    • 80 Ω (typical) at VCC - VEE = 4.5 V

    • 70 Ω (typical) at VCC - VEE = 6.0 V

    • 60 Ω (typical) at VCC - VEE = 9.0 V

  • Logic level translation: to enable 5 V logic to communicate with ±5 V analog signals

  • Typical ‘break before make’ built-in

  • Address latches provided

  • ESD protection:

    • HBM JESD22-A114F exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V

    • CDM JESD22-C101E exceeds 1000 V

  • Specified from -40 °C to +85 °C and -40 °C to +125 °C

Applications

  • Analog multiplexing and demultiplexing

  • Digital multiplexing and demultiplexing

  • Signal gating

Sample

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
