Description
The MK3727 series of devices include the original MK3727S, MK3727A, and the new MK3727C and MK3727D. The MK3727D and MK3727C are drop-in replacements for the MK3727S and MK3727A devices. Compared to these earlier devices the MK3727D and MK3727C offer a wider operating frequency range and improved power supply noise rejection. The MK3727D is recommended for new designs.
