SN74CBTLV3257: PCM Signal

Part Number: SN74CBTLV3257

Hi E2E,

Could SN74CBTLV3257 support PCM signal for select switch?


  • Julian,

    The passive FET switches are basically wires that are limited to a certain voltage range and signal bandwidth. They can support any signal modulation scheme like Pulse Code Modulation as long as the voltage level and bandwidth are within the recommended operating conditions of the switch.

    The SN74CBTLV3257 will support signals from 0 to 3.3 V and bandwidth <200MHz.

    What is the PCM signal voltage level and bandwidth in your application?
    Why did you choose the SN74CBTLV3257 instead of the newer TMUX1574?

    Thank you,
