- Description: The SN74CB3T3257 is a high-speed TTL-compatible FET multiplexer/demultiplexer with low ON-state resistance (r; ), allowing for minimal propagation delay. The device fully supports mixed-mode signal operation on all data I/O ports by providing voltage translation that tracks V; . The SN74CB3T3257 supports systems using 5-V TTL, 3.3-V LVTTL, and 2.5-V CMOS switching standards, as well as user-defined switching levels (see Figure 1).; The SN74CB3T3257 is a 4-bit 1-of-2 multiplexer/demultiplexer with a single output-enable (OE) input. The select (S) input controls the data path of the multiplexer/demultiplexer. When OE is low, the multiplexer/demultiplexer is enabled, and the A port is connected to the B port, allowing bidirectional data flow between ports. When OE is high, the multiplexer/demultiplexer is disabled, and a high-impedance state exists between the A and B ports.; This device is fully specified for partial-power-down applications using I; . The I; 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 V; through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the
