SED9420CAC

The SED9420CAC is a CMOS VFO data separator LSI for use in floppy disk interfaces. Equipped with its own SYNC field detection, loop filter switching, and timer functions, the IC allows construction of a one-chip VFO circuit with just a few external components.

The features of SED9420CAC: (1)data separation function using the VFO system; (2)recording can be switched between double density and single density; (3)requires no adjustment and few external circuits; (4)compatible with the IBM format; (5)single 5V power supply; (6)TTL-compatible I/O pins; (7)built-in timer circuit.

The absolute maximum ratings of the SED9420CAC are: (1)Supply voltage range: 0.5 to 7.0 V; (2)Input voltage range: 0.5 to VDD + 0.3 V; (3)output voltage: -10 to 60; (4)operating temperature: -10 to +60 ; (5)Storage temperature: -60 to +150 ; (6)Soldering temperature (10 seconds): 260 .
