This datasheet details the features of MAX9386/MAX9387/MAX9388, including application scenarios, pin definitions, working conditions, and package dimensions.
The MAX9386, MAX9387 and MAX9388 are fully differential, high‑speed, low‑jitter ECL/PECL multiplexers with optional output buffers. They are intended for clock‑and‑data distribution in telecom and datacom backplane applications, offering propagation delays as low as 318 ps (typ) and output‑to‑output skews of 3.9 ps (typ).\n\nThe devices operate from a wide supply range (VCC‑VEE 2.375 V to 5.5 V) and are offered in 20‑pin TSSOP/QSOP (MAX9386/8) and 24‑pin TSSOP/QSOP (MAX9387) packages. Detailed electrical characteristics, absolute maximum ratings, pin configurations and recommended PCB layout guidelines are provided.

The typical propagation delay is 318 ps.
A supply voltage range of 2.375 V to 5.5 V (VCC‑VEE) is required.
Terminate the outputs through 50 Ω to VCC‑2 V or use equivalent Thevenin terminations.
The continuous output current rating is 50 mA per pin.
