SEMICONDUCTOR TECHNICAL DATA The MC100LVEL56 is a dual, fully differential 2:1 multiplexer. The MC100EL56 is pin and functionally equivalent to the MC100LVEL56 but is specified for operation at the standard 100E ECL voltage supply. The differential data path makes the device ideal for multiplexing low skew clock or other skew sensitive signals. Multiple VBB pins are provided to ease AC coupling input signals (for more information on AC coupling ECL signals refer to the interfacing section of the ECLinPS data book DL140/D). The device features both individual and common select inputs to address both data path and random logic applications. The differential inputs have special circuitry which ensures device stability under open input conditions. When both differential inputs are left open the D input will pull down to VEE, The D input will bias around VCC/2 forcing the Q output LOW. • • • • • • • 20 1 DW SUFFIX PLASTIC SOIC PACKAGE CASE 751D–04 Differential Inputs and Outputs 20–Lead SOIC Packaging 440ps Typical Propagation Delays Separate and Common Select TRUTH TABLE Supports Both Standard and Low Voltage 100K ECL Internal Input Pulldowns SEL Data H L a b >2000V ESD Protection VCC Q0 Q0 SEL0 COM_SEL Logic Diagram and Pinout: 20-Lead SOIC (Top View) 20 19 18 17 16 SEL1 VCC 15 1 2 3 4 5 6 D0a D0a VBB0 D0b D0b D1a Q1 Q1 VEE 14 13 12 11 7 8 D1a VBB1 9 10 D1b D1b PIN NAMES Pins Function D0a–D1a D0b–D1b SEL0–SEL1 COM_SEL Q0–Q1 Q0–Q1 Input Data a Input Data b Individual Select Input Common Select Input True Outputs Inverted Outputs 4/95 Motorola, Inc. 1996 4–1 REV 1 MC100LVEL56 MC100EL56 MC100LVEL56 DC CHARACTERISTICS (VEE = –3.0V to –3.8V; VCC = GND) –40°C Symbol Characteristic Min IEE Power Supply Current VBB Output Reference Voltage –1.38 IIH Input HIGH Current IINL Input LOW Current 0°C Typ Max 20 24 –1.26 Min Typ Max 20 24 –1.38 –1.26 150 Dn Dn 0.5 –600 25°C Min Typ Max 20 24 –1.38 –1.26 150 0.5 –600 VPP(DC) Input Sensitivity1 50 50 1.
