SN74TVC3010 (ACTIVE) 10-Bit Voltage Clamp

10-Bit Voltage Clamp - SN74TVC3010


The SN74TVC3010 provides 11 parallel NMOS pass transistors with a common gate. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

The device can be used as a 10-bit switch with the gates cascaded together to a reference transistor. The low-voltage side of each pass transistor is limited to a voltage set by the reference transistor. This is done to protect components with inputs that are sensitive to high-state voltage-level overshoots. (See Application Information in this data sheet.)

All of the transistors in the TVC array have the same electrical characteristics; therefore, any one of them can be used as the reference transistor. Since, within the device, the characteristics from transistor to transistor are equal, the maximum output high-state voltage (VOH) is approximately the reference voltage (VREF), with minimal deviation from one output to another. This is a large benefit of the TVC solution over discrete devices. Because the fabrication of the transistors is symmetrical, either port connection of each bit can be used as the low-voltage side, and the I/O signals are bidirectional through each FET.
