    74CB3Q3253

    Dual 1-of-4 FET multiplexer/demultiplexer with charge pump

    The 74CB3Q3253 is a dual high-bandwidth single-pole, quad-throw FET bus switch. Each switch features a select input (Sn) and an output enable input (nOE). The switch is disabled when the nOE input is HIGH. An internal charge-pump increases the gate voltage of the NMOS pass transistor. The result is improved RON and RON(flat) performance and the ability to switch 5 V signals when VCC = 3.3 V.

    特性

    • Wide supply voltage range from 2.3 V to 3.6 V

    • Overvoltage switching on switch ports:

      • 0 V to 5 V switching with VCC = 2.5 V

      • 0 V to 5 V switching with VCC = 3.3 V

    • Switch voltage accepts signals up to 5.5 V

    • 4 Ω (typical) ON resistance

    • 3.5 pF (typical) OFF-state capacitance

    • High bandwidth 0.5 GHz (maximum)

    • Low input/output capacitance minimizes loading and signal distortion

    • Fast switching frequency fmax = 20 MHz (maximum)

    • Low power consumption ICC = 0.4 mA (typical)

    • Control inputs can be driven by TTL or 5 V/3.3 V CMOS outputs

    • IOFF supports partial power-down mode operation

    • Latch-up performance exceeds 100 mA per JESD 78E Class II Level A

    • ESD protection:

      • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

      • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

    • Specified from -40 °C to +85 °C

    目标应用

    • Communication infrastructure

    • Bus isolation

    • Memory interleaving

    • Sensor multiplexing
