Additional Details:

The DG243CK features a typical on-resistance of 85 Ohms, which is crucial for minimizing signal attenuation. Its fast switching speeds (150 ns turn-on and 100 ns turn-off) allow it to be used in high-speed applications. The low charge injection characteristic (5 pC) is essential for maintaining signal integrity in sensitive circuits. The device operates from a single supply voltage ranging from +4.5 V to +18 V, and it is directly compatible with both TTL and CMOS logic levels. The break-before-make switching action prevents momentary short circuits that can occur when switching between channels, enhancing the overall reliability of the system. The DG243CK comes in a 16-pin DIP package, making it easy to integrate into existing circuits.
