The ICM7556ISD+T packs two independent 555-type timer/oscillator circuits into a single 14-SOIC package, saving board area compared to using two single 555s. Each timer section can be configured for monostable, astable, or time-delay operation, with a maximum oscillation frequency of 500 kHz — fast enough for most PWM, pulse generation, and timing loops in industrial and consumer designs.
Temperature grade and package — fit for production and rework
Rated for -20°C to 85°C ambient, this part suits controlled indoor environments, telecom cabinets, and automotive cabin applications — not extended industrial or under-hood. The 14-SOIC (0.154" body width, 3.90 mm) is a standard JEDEC outline, compatible with common solder reflow profiles and pick-and-place equipment.
Active lifecycle and compliance — sourcing posture
Analog Devices lists this part as Active (current production), with RoHS3 compliance. The dual 555 function is a classic building block, and this SOIC package is a common footprint — no board-spin needed to drop it into an existing 14-SOIC timer slot.
