The TC7SET126FU,LJ is a member of Logic - Buffers, Drivers, Receivers, Transceivers and is ideal for applications where low power, high speed, and excellent system noise immunity are required. Its common-mode transient immunity (TMCL) is specified up to 25kV/us and is expected to deliver a guaranteed performance in any noise environment.

The TC7SET126FU,LJ is applicable for a variety of interface operations, such as level shifting/level conversion, demultiplexing, multiplexing, and high-speed input buffer from the General Purpose Digital Inputs (GPI). It is an active high-side 3A source/sink Transistor-based switch that uses three p-channel FETs for independent high-side driving, which allows the user to select and switch two devices between the high-side and the low-side buses. The current-limit feature provides protection against circuit faults, while the fail-safe logic feature prevents the device from entering a state when no logic signal is present.

In terms of working principle, the TC7SET126FU,LJ utilizes three p-channel FETs to drive the low-side bus, with each p-channel FET configured to give an independent high-side driver. The PC-pin is used to enable/disable the driver, while the REF pin is used to bias the p-channel FET of the device when in the logic high state (thereby preventing FET turn-on under load). The system logic input (ILLV) is applied to the logic control input to enable or disable the device in high level logic. The internal pull-down resistor ensures logic source is disabled until the logic control input is pulled up through an external pull-up resistor.

The TC7SET126FU,LJ contains integrated voltage shunt regulators, which allow the user to select the input voltage reference of ±2, ±5, or ±12V. This feature reduces external components, making the device more compact and cost-effective. Furthermore, the device also features wide operating temperatures ranging from -40°C to +85°C and offers reversed-current protection to further keep the system safe.

To summarize, the TC7SET126FU,LJ is an ideal choice for applications requiring low power consumption, high switching speeds, excellent system noise immunity, and wide operating temperatures. With its integrated voltage shunt and protected push-pull buffers, the device serves as an effective and reliable solution to many interface operations and circuit requirements.
