Логическая ИС SN74CB3T3257PW

FET Multiplexer / Demultiplexer , 4 Channels, 2:1, 2.3 V to 3.6 V, TSSOP-16

The SN74CB3T3257PW is a 4-bit 1-of-2 high-speed TTL-compatible FET Multiplexer/Demultiplexer with low ON-state resistance (ron), 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 VCC. It supports systems using 5V TTL, 3.3V LVTTL and 2.5V CMOS switching standards, as well as user-defined switching levels. It comes with a single 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 Ioff.

• Bidirectional data flow, with near-zero propagation delay
• Low input/output capacitance minimizes loading
• Data and control inputs provide undershoot clamp diodes
• Low power consumption
• Control inputs can be driven by TTL or 5/3.3V CMOS outputs
• Ioff Supports partial-power-down mode operation
• Latch-up performance exceeds 250mA per JESD 17
• Green product and no Sb/Br
