description
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 (V ) will be approximately the reference voltage (V
), with

minimum 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.
The SN74TVC3010 is characterized for operation from –40°C to 85°C.
