1 Si998 ishay Siliconix Buffered H-Bridge DESCRIPTION The Si998 is an integrated, buffered H-bridge with TTL compatible inputs and the capability of delivering a continuous. A at DD = (room temperature) at switching rates up to khz. Internal logic prevents the upper and lower outputs of either half-bridge from being turned on simultaneously. Unique input codes allow both outputs to be forced low (for braking) or forced to a high impedance level. The Si998 is available in both standard and lead (Pb)-free, 8-pin SOIC packages, specified to operate over a voltage range of.8 to., and the commercial temperature range of to 7 C (C suffix) and the industrial temperature range of - to 85 C (D suffix).
