Abstract
A differential switch accepts a binary control signal and its complement (which may be skewed with respect to the control signal) and latches both signals simultaneously. The latched output signals drive the control terminals of a differential switch pair which connects one of two terminals to a third terminal, depending upon the state of the control terminals. The differential switch may optionally include an inverter which complements the binary control signal, thus eliminating the need for external inversion of the control signal. The switch is particularly applicable for use in a digital to analog converter.
