74CB3Q3257-Q100

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

Rev. 1 — 20 February 2019

Product data sheet

1. General description

The 74CB3Q3257-Q100 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.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 3) and is suitable for use in automotive applications.

2. Features and benefits

•

Automotive product qualification in accordance with AEC-Q100 (Grade 3)

Specified from -40 °C to +85 °C

•

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:

•

MIL-STD-883, method 3015 exceeds 2000 V

HBM ANSI/ESDA/Jedec JS-001 Class 2 exceeds 2 kV

3. Applications

•

Communication infrastructure

Bus isolation

Memory interleaving

Sensor multiplexing
