her, the output can be switched alternately between the two input signals. When the gate level is high (1.5 V), a signal applied between pins 5 and 6 (channel A) will be passed and a signal applied between pins 3 and 4 (channel B) will be suppressed. In this manner, a binary-to-frequency conversion is obtained that is directly related to the binary sequence, which is driving the gate input (pin 2).
