5-BIT 2:1 MULTIPLEXER FEATURES DESCRIPTION ■ 550ps max. D to output ■ Extended 100E VEE range of –4.2V to –5.5V The SY10/100E158 offer five 2:1 multiplexers with differential outputs, designed for use in new, highperformance ECL systems. The multiplexer operation is controlled by the SEL (Select) signal which selects one of the two bits of input data at each mux to be passed through. ■ 775ps max. SEL to output ■ Differential outputs ■ Fully compatible with industry standard 10KH, 100K ECL levels ■ Internal 75KΩ input pulldown resistors ■ Fully compatible with Motorola MC10E/100E158 ■ Available in 28-pin PLCC package Q4 VCCO Q0 Q4 MUX SEL D4a D3b D0a D3a VCCO PIN CONFIGURATION BLOCK DIAGRAM D0b SY10E158 SY100E158 Q0 25 24 23 22 21 20 19 D2a D2b MUX SEL Q3 D2a D2b 27 17 Q1 28 16 1 15 2 14 Q2 Q2 VEE SEL D0a Q3 VCC Q2 13 Q2 D0b 4 VCCO Q1 PLCC TOP VIEW J28-1 3 12 D3a D3b MUX SEL D4a D4b MUX SEL 6 D1a D1b 5 Q3 Q3 7 8 9 10 11 Q0 MUX SEL 18 Q1 VCCO Q1 D1b 26 VCCO Q0 D1a D4b Q4 Q4 PIN NAMES SEL Pin Function D0a–D4a Input Data a D0b–D4b Input Data b SEL Select Input Q0–Q4 True Outputs Q0–Q4 Inverted Outputs VCCO VCC to Outputt Rev.: C 1 Amendment: /1 Issue Date: February, 1998 SY10E158 SY100E158 Micrel TRUTH TABLE SEL Data H a L b DC ELECTRICAL CHARACTERISTICS VEE = VEE (Min.) to VEE (Max.); VCC = VCCO = GND TA = 0°C Symbol IIH Parameter TA = +25°C Min.
