Doepfer A-152 Voltage Adressed Switch

Addressed Track&Hold / Analog Shift Register (ASR)/ Octal Switch (Multiplexer) Module A152 is a very useful switching and T&H module. It combines a voltage addressed 1-to-8 multiplexer and 8 fold T&H that can be used as an analog shift register too. The active in/output is displayed by a LED.

The digital output of the currently addressed step outputs "high". The remaining digital outputs are low.

Instead of voltage control even clock/reset controlled addressing of the active step is possible. The rising edge of each clock signal causes an advance to the next state. The rising edge of the reset signal resets to step 1.!!!
