MAX9384 19-2484 Rev 0 7/02 ECL/PECL Dual Differential 2:1 Multiplexer General Description Features The MAX9384 fully differential dual 2:1 multiplexer 40ps Deterministic Jitter P-P (mux) features extremely low propagation delay (560ps 440ps Differential Propagation Delay max) and output-to-output skew (40ps max). The device is ideal for clock and data multiplexing applica- 12ps Output-to-Output Skew tions. The two 2:1 muxes are controlled individually or Individual and Common Select simultaneously through mux select inputs COM SEL, SEL0, and SEL1. The mux select inputs are compatible +3.0V to +5.5V Supplies for Differential with ECL/PECL logic, and are referenced to on-chip LVPECL/PECL outputs V and V , nominally V - 1.33V. BB0 BB1 CC -3.0V to -5.5V Supplies for Differential LVECL/ECL The differential inputs D, D can be configured to accept a single-ended signal when the unused complementary Outputs Low for Inputs Open or at V EE input is connected to the on-chip supply output V as BB >2kV ESD Protection (Human Body Model) a reference voltage. All the differential inputs have bias and clamp circuits that force the outputs to a low Pin Compatible with MC100LVEL56 and default when the inputs are left open or at V . The sin- EE MC100EL56 gle-ended mux select inputs have pulldowns to V , EE providing low default inputs when the select inputs are left open. Ordering Information The device operates with a wide supply range (V - CC V ) of +3.0V to +5.5V for PECL or -3.0V to -5.5V for EE PART TEMP RANGE PIN-PACKAGE ECL, and is pin compatible with the MC100LVEL56 and MAX9384EWP -40C to +85C 20 Wide SO MC100EL56. The MAX9384 is offered in a 20-pin wide SO package, and is specified for operation from -40C to +85C.
