U74CBT3257C
Overview
The UTC U74CBT3257C is a 4-BIT 1-OF-2 FET multiplexer/ demultiplexer with Low ON-State Resistance (RON) and TTL-compatibility.
- Undershoot Protection for Off-Isolation on A and B Ports Up to -2V * VCC Operating Range From 4V to 5.5V
- Bidirectional Data Flow, With Near-Zero Propagation Delay
- Low ON-State Resistance (RON) Characteristics (RON =4Ω Typ.) * Low Power Consumption ICC =3μA (Max) * Data and Control Inputs Provide Undershoot Clamp Diodes
- Data I/Os Support 0 to 5-V Signaling Levels (0.8V, 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V)
- Control Inputs Can be Driven by TTL or 5V/3.3V CMOS Outputs
- IOFF Supports Partial-Power-Down Mode Operation * Supports I2C Bus Expansion
