SN74CBTLV3257: looking lower propagation delay

An analog switch, when closed, behaves like a resistor. To reduce the propagation delay, choose a switch with a lower on-resistance and/or a lower capacitance.

Anyway, the search function shows the bandwidth of each device. The TMUX1574 has 2 GHz (compared to the SN74CBTLV3257's 200 MHz).

Hi Ben,

We have several devices that will fit your use case. For a sub-nanosecond propagation delay, 2:1x4 mux, please see the below recommendations:

1) SN74CB3Q3257 - 0.32ns max delay at 3.3V (pin-to-pin replacement)

2) TMUX1574 - 95ps typical across voltage (pin-to-pin replacement)

3) TMUX1575 - 60ps typical across voltage (similar device to the TMUX1574, but in a WCSP package - smallest package solution)

Thanks!
