To achieve high-voltage ratings and superior switching performance, the G417 series is built on iliconix s high voltage silicon gate (HVG) process. Break-before-make is guaranteed for the G419, which is an PT configuration. An epitaxial layer prevents latchup. The G417 and G418 respond to opposite control logic levels as shown in the Truth Table.

This circuit is useful when signals have to be routed to either of two remote loads. Only three conductors are required: one for the signal to be switched, one for the control signal and a common return. A positive input pulse turns on the clamping diode 1 and charges 1. The charge stored on 1 is used to power the chip; operation is satisfactory because the switch requires less than 1 A of stand-by supply current. Loading of the signal source is imperceptible.

10 G417/418/419 Applications (ont d) Micropower UP Transfer witch When V drops to 3.3 V, the G417 changes states, closing W 1 and connecting the backup cell, as shown in Figure prevents current from leaking back towards the rest of the circuit. urrent consumption by the MO analog switch is around 1 pa; this ensures that most of the power available is applied to the memory, where it is really needed. In the stand-by mode, hundreds of A are sufficient to retain memory data. When the -V supply comes back up, the resistor divider senses the presence of at least 3. V, and causes a new change of state in the analog switch, restoring normal operation. Programmable Gain Amplifier The G419, as shown in Figure 12, allows accurate gain selection in a small package. witching into virtual ground reduces distortion caused by r (on) variation as a function of analog signal amplitude. GaAs FET river The G419, as shown in Figure 13 may be used as a GaAs FET driver. It translates a TTL control signal into 8-V, -V level outputs to drive the gate.
