The -40°C to 85°C industrial temperature range suits it for factory automation, outdoor telecom, and motor-drive control boards where the ambient inside the enclosure can climb. ## Lifecycle and sourcing posture The 551MILF carries an Active lifecycle status with ROHS3 compliance.","metaTitle":"551MILF Fanout Buffer (Distribution), 160 MHz, 8-SOIC","metaDescription":"IDT 551MILF ClockBlocks™ fanout buffer: 1:4 CMOS, 160 MHz max, 3V–5.5V supply, -40°C to 85°C, 8-SOIC.

It is suitable for ongoing production and new designs."},{"question":"Does 551MILF support differential input?","answer":"No. The 551MILF is single-ended only — both input and output are CMOS. For differential clock distribution (LVDS, LVPECL), look at parts like the 8SLVP1104ANLGI."},{"question":"What is the maximum frequency of 551MILF?","answer":"160 MHz is the maximum rated frequency.

The 551M variant (non-LF) is the older tin-lead version.
