2-BIT 8:1 MULTIPLEXER FEATURES SY10E163 SY100E163 DESCRIPTION ■ 850ps max. propagation delay ■ Extended 100E VEE range of –4.2V to –5.5V The SY10/100E163 offer two 8:1 multiplexers designed for use in new, high-performance ECL systems. The E163 has differential outputs and common select inputs. The select inputs (SEL0, SEL1, SEL2) determine which one of the eight data inputs (A0–A7, B0–B7) is propagated to the output. ■ Differential outputs ■ Internal 75KΩ input pulldown resistors ■ Fully compatible with industry standard 10KH, 100K ECL levels ■ Fully compatible with Motorola MC10E/100E163 ■ Available in 28-pin PLCC package B7 VCCO PIN CONFIGURATION BLOCK DIAGRAM A2 A3 B6 B4 B5 B2 B3 A0 A1 25 24 23 22 21 20 19 A6 A7 QB B0 SEL0 VEE SEL1 SEL2 27 17 28 16 QB VCC NC A0 PLCC TOP VIEW J28-1 1 2 15 14 3 13 4 12 5 A1 A2 SEL0 SEL1 6 7 8 9 10 11 A6 A7 A5 18 A5 A4 26 A3 A4 QA QA B1 VCCO QA QA SEL2 TO SIDE B PIN NAMES Pin Function A0–A7 A Data Inputs (D) B0–B7 B Data Inputs (D) SEL0, 1, 2 Select Inputs QA, QB True Outputs QA, QB Inverting Outputs VCCO VCC to Output Rev.: C 1 Amendment: /1 Issue Date: February, 1998 SY10E163 SY100E163 Micrel TRUTH TABLE SEL0 A/B Data L L 0 L H 1 L H L 2 L H H 3 H L L 4 H L H 5 H H L 6 H H H 7 SEL2 SEL1 L L DC ELECTRICAL CHARACTERISTICS VEE = VEE (Min.) to VEE (Max.); VCC = VCCO = GND TA = 0°C Symbol Parameter TA = +25°C Min.
