MADR-8888- Rev. Features High Drive Current Capability (± ) 7 Back Bias in Off State Switching Speed Approximately. Low Current Coumption Land Grid Array Package for SMT Applicatio Tape and Reel Packaging Available Lead-Free Package 6 C Reflow Compatible RoHS* Compliant Single CMOS Logic input Description M/A-COM Technology Solutio MADR-8888- Switch Driver is designed to work with M/A- COM Tech switch MASW-8-77T or other series / series switches. This driver is design to provide currents up to for each diode in series / series switches. It is designed for SPDT switches that operate with a power range of approximately W CW. The driver is packaged in a Land Grid Array surface mount package and is available in tape and reel packaging for high volume applicatio. The MADR-8888- driver is ideally suited for driving M/A-COM s line of HMIC switches. Note that this driver will also operate when DD is set to voltages other than +8. It could also operate at +, +, +, and + supplies.
