74CB3Q3253  
Dual 1-of-4 FET multiplexer/demultiplexer with charge pump  
Rev. 1 — 14 August 2017  
Product data sheet  
1 General description  
The 74CB3Q3253 is a dual high-bandwidth single-pole, quad-throw FET bus switch.  
Each switch features a select input (Sn) and an output enable input (nOE). The switch  
is disabled when the nOE 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  
Switch voltage accepts signals up to 5.5 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-001-2012 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
