description/ordering information
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 (V
OH
) is approximately the reference voltage (V
REF
), with
minimal deviation from one output to another. This is a 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.
