Nexperia 74CB3Q3253PW,118

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.

• Wide supply voltage range from 2.3 V to 3.6 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)
