    Hi Jazz,

    We don't have a p2p for the parts you have listed above. However, we do have products that are similar. See below.

    1. PI3USB14-AZHE vs SN74CB3Q3253.

      Diode TI
    Family PI3USB14-A SN74CB3Q3253
    PN PI3USB14-AZHEX SN74CB3Q3253RGY
    Configuration 2 Channel 4:1 MUX 2 Channel 4:1 MUX
    Supply Voltage 3.3V Operation 2.3 - 3.6V
    Propagation Delay 0.3 ns 0.18 ns
    Ron 4.0 Ω (typ) 4.0 Ω (typ)
    BW (-3dB) 815 MHz 500 MHz
    OFF Leakage Current < +/- 2 µA < +/- 1 µA
    Package TQFN - 20-pin Very Thin Quad Flat, No Lead (TQFN) (3.5mm x 4.5mm x 0.75 mm) VQFN - 16-pin Very Thing Quad Flat, No Lead (VQFN) (3.5mm x 4.0mm x 0.9 mm
    Notes Wider Bandwidth Lower OFF leakage current, Lower propagation delay

    2. PI3USB103ZLE vs TMUX136. The TMUX136 has wider bandwidth and has charge pump. 

      Diode TI
    Family PI3USB130 TMUX136
    PN PI3USB103ZLE TMUX136RSER 
     Configuration 2 Channel 2:1 SPDT 2 Channel 2:1 SPDT
    Supply Voltage 2.7 - 4.2V Operation 2.3 - 4.8V Operation
    Propagation Delay 0.25 ns 0.10 ns
    Ron 3.0 Ω (typ) 5.7 Ω  (typ)
    BW (-3dB) 1.5 GHz 6.1 GHz
    OFF Leakage Current < +/- 2 µA < +/- 2 µA
    Package 10-contact, Thin Fine Pitch Quad Falt No-Lead (TQFN) Package (1.3mm x 1.6mm x 0.75mm) Compact 10-Pin UQFN Package (1.5mm x 2mm, 0.5mm Pitch)
    Notes Lower Ron Includes Charge Pump, Wider Bandwidth, Lower Propagation Delay

    Thanks,
    Jon
