The NL506 Analogue Switch contains a single pole change-over analogue switch. The state of which is controlled by a logic signal. This signal can be generated externally or by the internal Flip-Flop switch that can be toggled by the negative going edge of a logic input. A front panel switch allows direct selection of the switch state which is indicated by an LED.
The switch is bi-directional allowing it to be used as a 1-input, 2-output or a 2-input, 1-output device. Also, as the NL506 Analogue Switch is analogue, it can handle signals up to +15V as well as being of low enough impedance to handle TTL signals.
