74CBTLV3257DS,118

The Nexperia 74CBTLV3257DS,118 is a quad 1-of-2 high-speed multiplexer/demultiplexer. It features common select (S) and output enable (OE) inputs. The device operates within a supply voltage range of 2.3 V to 3.6 V and is specified for an operating temperature range of -40 °C to +125 °C.

This multiplexer/demultiplexer offers low ON resistance, allowing inputs to connect to outputs without significant propagation delay or ground bounce noise. When the output enable (OE) pin is LOW, one of the two switches is selected based on the select (S) pin. When OE is HIGH, all switches enter a high-impedance OFF-state, independent of the S pin. The Schmitt trigger action at the control input provides tolerance to slower input rise and fall times.

The device is suitable for partial power-down applications due to its IOFF circuitry, which prevents damaging backflow current when the device is powered down. It complies with JEDEC standards JESD8-5 (2.3 V to 2.7 V) and JESD8-B/JESD36 (2.7 V to 3.6 V). The 74CBTLV3257DS,118 is available in a 16-SSOP package and is surface-mountable.

Key electrical characteristics include a 5 Ω switch connection between ports and rail-to-rail switching on data I/O ports. It exhibits CMOS low power consumption and latch-up performance exceeding 250 mA per JESD78B Class I level A. ESD protection is provided, with HBM exceeding 2000 V and CDM exceeding 1000 V.
