资 源 简 介
The SN74TVC16222A provides 23 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 22-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. Because, 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.
