The standard set-up level is 7.5 IRE. The SPT1018 ispin-compatible with the HDAC10180 and the TDC1018, withimproved performance. The SPT1018 contains data andcontrol input registers, video control logic, reference buffer,and current switches.
The SPT1018 is available in a 24-lead PDIP package in thendustrial temperature range.Contact the factory for militaryemperature and/883 versions.
