74CB3Q3257BQ Datasheet | Nexperia

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 p F (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 m A (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 m A per JESD 78E Class II Level A - ESD protection: - HBM ANSI/ESDA/JEDEC JS-001-2012 Class 2 exceeds 2 k V - CDM JESD22-C101F exceeds 1000 V - Specified from -40 °C to +85 °C 3 Applications - munication 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. Ordering information Type number Package Temperature range 74CB3Q3257PW -40 °C to +85 °C 74CB3Q3257BQ -40 °C to +85 °C Name Description Version TSSOP16 plastic thin shrink small outline package; 16 leads; body width 4.4 mm SOT403-1 DHVQFN16 plastic dual in-line patible 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...
