Built on the proprietary high-voltage silicon-gate process to achieve high voltage rating and superior switch on/off performance, break-before-make is guaranteed for the PT configurations. Each switch conducts equally well in both directions when on, and blocks up to V peak-to-peak when off. On-resistance is very flat over the full 15-V analog range. The G1B has two independent PT switches. The G3B has four PT switches in NO/ combinations. The G5B has four switches in two PT pairs. (ee Functional Block iagrams and Pin onfigurations on pages 1 and 2.) The G1B/3B/5B is available in both 16-pin plastic dip and 16-pin OI packages. As a committed partner to the community and the environment, manufactures this product with the lead (Pb)-free device terminations. For analog switching products manufactured with 0% matte tin device terminations, the lead (Pb)-free E3 suffix is being used as a designator.

9 New Product G1B/3B/5B APPLIATION Peak etector A 3 acting as a comparator provides the logic drive for operating W 1. The output of A 2 is fed back to A 3 and compared to the analog input e in. If e in > e out the output of A 3 is high keeping W 1 closed. This allows 1 to charge up to the analog input voltage. When e in goes below e out A 3 goes negative, turning W 1 off. The system will therefore store the most positive analog input experienced. Reset W 2 e in A1 + W 1 R 1 + A 2 e out + A 3 G1B 1 FIGURE 12. Positive Peak etector Rev. A, -Jan-05 9
