MAX9388EUP+T

The MAX9386/MAX9387/MAX9388EUP are fully differential, high-speed, low-jitter ECL/PECL multiplexers (muxes) with output buffer(s). The devices are designed for clock-and-data distribution applications, and feature extremely low propagation delays (318ps, typ) and output-to-output skews (3.9ps, typ). The MAX9386 is a 5:1 mux with a single output buffer. The MAX9387 is a 5:1 mux with dual output buffers, and is intended for use in redundant systems. The MAX9388EUP is a 4:1 mux with a single output buffer, and is pin compatible with the MC100EP57. Three single-ended select inputs, SEL0, SEL1, and SEL2, control the mux function on the MAX9386/MAX9387. The MAX9388EUP has two select inputs, SEL0 and SEL1. The mux select inputs are compatible with ECL/PECL logic, and are internally referenced to the on-chip output VBB, nominally VCC - 1.425V. The select inputs accept signals between VCC and VEE. Internal pulldowns to VEE ensure a low-default condition if the select inputs are left open. The differential inputs D_, D_ -bar can be configured to accept a single-ended signal when the unused complementary input is connected to the on-chip reference output VBB. All the differential inputs have internal bias and clamping circuits that ensure low-default output states when the inputs are left open. The MAX9386/MAX9387/MAX9388EUP operate with a wide supply range |VCC - VEE| of 2.375V to 5.5V. The MAX9386/MAX9388EUP are offered in 20-pin TSSOP and QSOP packages. The MAX9387 is offered in 24-pin TSSOP and QSOP packages.
