Texas Instruments Integrated Circuits (ICs) - Logic - Signal Switches, Multiplexers, Decoders SN74CBTD3305CPWR

The SN74CBTD3305CPWR is a dual FET bus switch designed for high-speed applications, featuring low ON-state resistance of approximately 3 Oc, which minimizes propagation delay. It supports bidirectional data flow and is capable of level shifting from 5 V inputs to 3.3 V outputs, making it suitable for interfacing between different voltage levels. The device includes undershoot protection for the A and B ports, safeguarding against voltage undershoot down to -2 V. This bus switch operates within a supply voltage range of 4.5 V to 5.5 V and is compatible with TTL and CMOS control inputs. It also supports partial-power-down mode through the Ioff feature, preventing backflow of current when powered down. The SN74CBTD3305CPWR is specified for operation in temperatures ranging from -40¬8C to 85¬8C and is suitable for both digital and analog applications, including USB interfaces and bus isolation. Its low input/output capacitance of 5 pF helps minimize loading and signal distortion, making it a reliable choice for various engineering projects.
