SN74TVC16222ADGGR

The SN74TVC16222ADGGR is a 22-channel voltage clamp integrated circuit manufactured by Texas Instruments. Part of the Widebus family, this device is engineered for voltage-limiting applications, protecting sensitive components from high-state voltage overshoots. It provides 23 parallel NMOS pass transistors with a common gate, allowing for minimal propagation delay due to low on-state resistance.

The device can function as a 22-bit switch, with gates cascaded to a reference transistor. The low-voltage side of each pass transistor is limited by a reference transistor, ensuring the output high-state voltage (VOH) is approximately the reference voltage (VREF) with minimal deviation. This symmetrical transistor fabrication allows either port connection to be used as the reference.

Packaged in a 48-TSSOP, the SN74TVC16222ADGGR is suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. The device offers direct interface with GTL+ levels and includes ESD protection exceeding JESD 22 standards.

Key specifications include 22 bits of switching capability, a voltage clamp logic type, and a surface mountable 48-TSSOP package. It is designed for ease of PCB trace routing with a flow-through pinout.
