The Master Reset has an internal pull-up resistor and is normally used with a 0.1F capacitor. During power up all switches are automatically reset. The crosspoint switches will reset with MR = 0 even if CE is high. A 6-bit address through a 6 line to 64 line decoder selects the transmission gate which can be turned on by applying a logic ONE to the DATA input and logic ZERO to the STROBE. Similarly, any transmission gate can be turned OFF by applying a logic ZERO to the DATA input while strobing the STROBE with a logic ZERO.
