74CB3Q3257

4-bit 1-of-2 FET multiplexer/demultiplexer with charge pump

The 74CB3Q3257 is a quad high-bandwidth single-pole, double-throw FET bus switch. The device features one select input (S) and one output enable input (OE). The switch is disabled when the OE 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

  • 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
