Application Scenarios & Design Considerations

Dual 1-of-4 FET Mult/Demult 2.5-V/3.3-V Low-Voltage Bus Switch with 5-V Tolerant Level Shifter

Alternative Part Number

  • PI3B3253QEX --: Pin-compatible 2:1 dual 4-channel bus switch with similar low on-resistance and TSSOP package, direct functional drop-in for the CB3T3253.
  • 74CB3Q3253PWR --: Same 3.3V bus-switch function with 2:1 multiplexer architecture and TSSOP-16 footprint, offering comparable signal integrity and level translation.
  • MAX4760EUE+ --: Low-voltage dual 4:1 bus switch/mux with similar switching characteristics and TSSOP package, suitable as a functional substitute when exact pinout is not critical.
