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
    • 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 JESD78EClassIILevelA
  • ESD protection:
    • HBM ANSI/ESDA/JEDEC JS-001-2012 Class 2 exceeds 2 kV
    • CDM JESD22-C101F exceeds 1000 V
  • Specified from -40 °C to +85 °C

目标应用

  • Communication infrastructure
  • Bus isolation
  • Memory interleaving
  • Sensor multiplexing
