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 R_ONand R_ON(flat)performance and

the ability to switch 5 V signals when V_CC= 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 V_CC= 2.5 V

– 0 V to 5 V switching with V_CC= 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 f_max= 20 MHz (maximum)

• Low power consumption I_CC= 0.4 mA (typical)

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

• I_OFFsupports 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-001-2012 Class 2 exceeds 2 kV

– CDM JESD22-C101F exceeds 1000 V

• Specified from -40 °C to +85 °C

3 Applications

• Communication infrastructure

• Bus isolation

• Memory interleaving

• Sensor multiplexing
