FSTD31254-Bit Bus Switch with Level Shifting | Signal Switches, Multiplexers, Decoders | 5 | Active | ON Semiconductor switch FSTD3125 provides four high-speed CMOS TTL-compatible bus switches. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. A diode to VCChas been integrated into the circuit to allow for level shifting between 5V inputs and 3.3V outputs.The device is organized as four one-bit switches with separate /OE inputs. When /OE is LOW, the switch is ON and port A is connected to port B. When /OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports. |

FSTU3216016-Bit to 32-Bit Multiplexer/Demultiplexer Bus Switch with -2 V Under-Shoot Protection | Logic | 3 | Active | The ON Semiconductor switch FSTU32160 is a 16-bit to 32-bit high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.The device can be used in applications where two buses need to be addressed simultaneously. The FSTU32160 is designed so that the A Port demultiplexes into B1or B2or both. The A and B Ports have "undershoot hardened" circuit protection to support an extended range to 2.0V below ground. The integrated undershoot hardened circuit senses undershoot at the I/Os, and responds by preventing voltage differentials from developing and turning on the switch.Two select (S1, S2) inputs provide switch enable control. When S1, S2are HIGH, the device precharges the B Port to a selectable bias voltage (Bias V) to minimize live insertion noise. |

FSUSB104Low Power, Two-Port, Hi-Speed USB2.0 (480Mbps) Switch | Interface | 2 | Active | The FSUSB104 is a bi-directional, low-power, two-port, Hi-Speed, USB2.0 switch. Configured as a double-pole, double-throw switch (DPDT) switch, it is optimized for switching between two Hi-Speed (480Mbps) sources or a Hi-Speed and Full-Speed (12Mbps) source.The FSUSB104 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.7pF. The wide bandwidth of this device (720MHz) exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk also minimizes interference.The FSUSB104 contains special circuitry on the switch I/O pins for applications where the VCCsupply is powered-off (VCC=0), which allows the device to withstand an over-voltage condition. This device is designed to minimize current consumption even when the control voltage applied to the SEL pin is lower than the supply voltage (VCC). This feature is especially valuable to ultra-portable applications, such as cell phones, allowing for direct interface with the general-purpose I/Os of the baseband processor. Other applications include switching and connector sharing in portable cell phones, PDAs, digital cameras, printers, and notebook computers. |
FSUSB11Low Power Full Speed USB Switch | Interface | 1 | Obsolete | The FSUSB11 is a high-performance, dual Single-Pole Double-Throw (SPDT) switch designed for switching USB 1.1 signals. The device features ultra-low on resistance (RON) of 1.3Ω maximum at 4.5V VCCand 4.3Ω at 2.7V supply. High bandwidth and ultra-low on resistance (RON) make this switch able to pass both USB low- and full-speed signal with minimum signal distortion. The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation. The select input is TTL level compatible. |
