The SN74CBTLV3257 device is a 4-bit 1-of-2 high-speed FET multiplexer/demultiplexer. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.
●The select (S) input controls the data flow. The FET multiplexers/demultiplexers are disabled when the output-enable (OE) input is high.
●This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off.
●To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
● 5-Ω Switch Connection Between Two Ports
● Rail-to-Rail Switching on Data I/O Ports
● Ioff Supports Partial-Power-Down Mode Operation
● Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
● ESD Protection Exceeds JESD 22
● 2000-V Human-Body Model (A114-A)
● 200-V Machine Model (A115-A)
