description/ordering information
●The SN74CBT3244C is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron), allowing for minimal propagation delay. Active Undershoot-Protection Circuitry on the A and B ports of the SN74CBT3244C provides protection for undershoot up to −2 V by sensing an undershoot event and ensuring that the switch remains in the proper OFF state.
●• Undershoot Protection for Off-Isolation on A and B Ports Up To −2 V
●• Bidirectional Data Flow, With Near-Zero Propagation Delay
●• Low ON-State Resistance (ron) Characteristics (ron = 3 Ω Typical)
●• Low Input/Output Capacitance Minimizes Loading and Signal Distortion (Cio(OFF) = 5.5 pF Typical)
●• Data and Control Inputs Provide Undershoot Clamp Diodes
●• Low Power Consumption (ICC = 3 µA Max)
●• VCC Operating Range From 4 V to 5.5 V
●• Data I/Os Support 0 to 5-V Signaling Levels
● (0.8-V, 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, 5-V)
●• Control Inputs Can Be Driven by TTL or 5-V/3.3-V CMOS Outputs
●• Ioff Supports Partial-Power-Down Mode Operation
●• Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
●• ESD Performance Tested Per JESD 22
● − 2000-V Human-Body Model (A114-B, Class II)
● − 1000-V Charged-Device Model (C101)
●• Supports Both Digital and Analog
● Applications: USB Interface, Memory Interleaving, Bus Isolation, Low-Distortion Signal Gating
