On-resistance is less than 50Ω and is essentially constant over the analog signal range.
The switching difference between a TTL IC output and a CMOS IC input has to be accounted for.

Maxim’s DG300–DG303 and DG300A–DG303A CMOS dual and quad analog switches combine low power operation with fast switching times and superior DC and AC switch characteristics. To address the problem, simple CMOS analog switches can be used. 0.5 Ω CMOS, Dual 2:1 MUX/SPDT Audio Switch Data Sheet ADG884 Rev. The MAX6816/MAX6817/MAX6818 are single, dual, and octal switch debouncers that provide clean interfacing of mechanical switches to digital systems.

Most mechanical switches or relays are not designed for switching multimedia signals and can create interference such as a loud audio pop or visual interference. The MAX4644 offers fast switching times of less than 20ns while ensuring break-before-make operation.

They accept one or more bouncing inputs from a mechanical switch and produce a clean digital output after a short, preset qualification delay. D Information furnished by Analog Devices is believed to be accurate and reliable. However the difference in input logic switching level does impact your design, the TTL output does not correctly switch a CMOS input. Specifications subject to change without notice.

Switching circuits can be designed from scratch, but this adds complexity and time.

The output switching levels from CMOS ICs is higher then a TTL IC, which happens to result in a better design and does not have a negative effect. However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties that may result from its use. Both the switch opening bounce and the switch closing bounce are removed. It typically consumes only 0.01µW of quiescent power, making it suitable for … Our RF Switches are produced in high volume with proven Bulk CMOS technology at several factories and packaged either in very small plastic package best for PCB (Printed Circuit Board) mounting or in CSP (Chip Scale Package) ideal for highly integrated modules. Device specifications are ideal for battery-powered circuitry. Selecting the Right CMOS Analog Switch By: Usama Munir, Application Engineer David Canny, Application Engineer Jan 29, 2013 Abstract: With the large number of analog switches on the market today, there are many performance criteria for a product designer to consider.
Our switches and multiplexers (muxes) are part of a wide portfolio of multiplexers and signal switches that includes analog switch ICs, digital switches, translating switches, load switches, muxes, demultiplexers (demuxes), and specialty switches such as HDMI, LAN, VGA, DDR, video switches, audio jack switches, PCIe signal switch and USB/MHL switches.
