Logic - Signal Switches, Multiplexers and Decoders are key components of most electronic systems and are used in many different applications. The TC7USB221FT(EL,M) is a Logic/Signal switch that is used to either automatically or manually switch between two signal sources. The device is designed to have low on-resistance and low signal distortion when switching to either source. The on-chip signal protection feature ensures signal integrity even if transient voltage is applied. The TC7USB221FT(EL,M) is suitable for use in high speed signal switching circuits that require high signal integrity and low power consumption.

The TC7USB221FT(EL,M) is a negative logic switch with Quasi-TTL compatible inputs and outputs. It features high ON/OFF signal integrity, making it suitable for high frequency applications such as digital debug and micro processor communication. The device also features low on-resistance (Rds) and low power consumption (V_dd = 5V, 80μA typical), which makes it very suitable for high-speed signal switching. In addition, the switch has a maximum power dissipation of 100mW, making it suitable for battery operated systems.

The TC7USB221FT(EL,M) operates by controlling the signal transfer of a signal from one or two sources. The device is designed to have a low on-resistance value of 75 Ω, with a maximum signal attenuation of 0.5dB, which helps to reduce the signal distortion when switching between sources. The primary benefit of this device is that it can be used to switch signals without the need for additional components, such as relays or transistors, thereby reducing system cost and power consumption. In addition, the device also features an open-drain output that can be used as a data line repeater. This improves signal integrity by making sure that data signals are not distorted due to signal attenuation or cross-talk and reduces the risk of bit errors due to signal loss.

The TC7USB221FT(EL,M) is ideal for applications that require switching between two sources, such as battery power and USB power, as well as other high speed signal switching applications. The device’s low power requirement makes it suitable for powering battery operated devices, as well as low-power, portable systems. Additionally, its low signal distortion makes it suitable for high speed signal applications. In general, the TC7USB221FT(EL,M) is a suitable component for applications that require high-speed signal switching, low power consumption and signal integrity. Therefore, it is a perfect choice for applications in the consumer electronics, automotive and industrial markets, as well as any application that requires auto-swITCHING between two sources.
