1 G401B, G403B, G405B Low-Power, High-peed MO Analog witches ERIPTION The G401B, G403B, G405B monolithic analog switches are replacements for the popular G401/403/405 analog switches and provide improved performance, combining high speed (t ON : 0 ns, typ) with low power consumption make the G401B series ideal for portable and battery powered applications. Built on the proprietary high-voltage silicongate 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 30 V peak-to-peak when off. On-resistance is very flat over the full ± 15 V analog range. The G401B has two independent PT switches. The G403B has four PT switches in NO/ combinations. The G405B has four switches in two PT pairs (see Functional Block iagrams and Pin onfigurations on pages 1 and 2.) The G401B, G403B, G405B 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.

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 G401B 1 Figure 12.
