74CB3Q3257 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 and R performance and ON ON(flat) the ability to switch 5 V signals when V = 3.3 V. CC 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 = 2.5 V CC 0 V to 5 V switching with V = 3.3 V CC 4 (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 = 20 MHz (maximum) max Low power consumption I = 0.4 mA (typical) CC Control inputs can be driven by TTL or 5 V/3.3 V CMOS outputs I supports partial power-down mode operation OFF 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 multiplexingNexperia 74CB3Q3257 4-bit 1-of-2 FET multiplexer/demultiplexer with charge pump 4 Ordering information Table 1.Ordering information Type number Package Temperature Name Description Version range 74CB3Q3257PW -40 C to +85 C TSSOP16 plastic thin shrink small outline package 16 leads SOT403-1 body width 4.4 mm 74CB3Q3257BQ -40 C to +85 C DHVQFN16 plastic dual in-line compatible thermal enhanced very SOT763-1 thin quad flat package no leads 16 terminals body 2.5 x 3.5 x 0.85 mm 5 Functional diagram 1A 1B1 1B2 2A 2B1 2B2 3A 3B1 3B2 4A 4B1 4B2 S OE aaa-027232 Figure 1.
