Download the 74CB3Q3257BQ datasheet PDF. This datasheet also covers the 74CB3Q3257 variant, as both devices belong to the same 4-bit 1-of-2 fet multiplexer/demultiplexer family and are provided as variant models within a single manufacturer datasheet.

General Description

The 74CB3Q3257 is a quad high-bandwidth single-pole, double-throw FET bus switch.

Key Features

  • 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.

74CB3Q3257 4-bit 1-of-2 FET multiplexer/demultiplexer with charge pump Rev. 1 — 14 August 2017 Product data sheet 1 General description 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. 2 Features and benefits • 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.
