Nexperia B.V. 4-bit 1-of-2 FET multiplexer/demultiplexer with charge pump 74CB3Q3257BQX

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 OEinput is HIGH. An internal charge-pump increases the gate voltage of the NMOS pass transistor. The result is improved R_ON and R_ON(flat) performance and the ability to switch 5 V signals when V_CC = 3.3 V.

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_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_OFF 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 class 2 exceeds 2000 V
• CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
• Specified from -40 °C to +85 °C

Applications

• Communication infrastructure
• Bus isolation
• Memory interleaving
• Sensor multiplexing
