Overview
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 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 • 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 Nexperia 74CB3Q3257 4-bit 1-of-2 FET multiplexer/demultiplexer with charge pump 4 Ordering information Table 1.
