74CB3Q3253

74CB3Q3253 Dual 1-of-4 FET multiplexer/demultiplexer with charge pump Rev. 2 — 28 June 2021 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.
