MAX9384 is a dual 2:1 differential multiplexer from MAXIM. It features extremely low propagation delay (560ps max) and output-to-output skew (40ps max). It is ideal for clock and data multiplexing applications. The two 2:1 multiplexers are controlled individually or simultaneously through multiplexer select inputs COM_SEL, SEL0 and SEL1. The multiplexer select inputs are compatible with ECL/PECL logic and referenced to on-chip outputs VBB0 and VBB1, nominally VCC-1.33V. The differential inputs D, D can be configured to accept a single-ended signal when the unused complementary input is connected to the on-chip supply output VBB as a reference voltage. All the differential inputs have bias and clamp circuits that force the outputs to a low default when the inputs are left open or at VEE. The single-ended multiplexer select inputs have pulldowns to VEE, providing low default inputs when the select inputs are left open. The device operates with a wide supply range (VCC-VEE) of +3.0V to +5.5V for PECL or -3.0V to -5.5V for ECL and is pin compatible with the MC100LVEL56 and MC100EL56. The MAX9384 is offered in a 20-pin wide SO package and is specified for operation from -40°C to +85°C.
The MAX9384 dual differential 2:1 multiplexer offers extremely low propagation delay (560 ps max) and output‑to‑output skew (40 ps max), making it suitable for clock and data multiplexing in high‑speed telecom and datacom systems. It operates from a wide supply range of +3.0 V to +5.5 V for PECL or –3.0 V to –5.5 V for ECL and is pin‑compatible with the MC100LVEL56 and MC100EL56.
The device is supplied in a 20‑pin wide SO package, rated for –40 °C to +85 °C operation, and includes over‑2 kV ESD protection. Detailed pin descriptions, absolute maximum ratings, and electrical characteristics are provided for designers.
