QUAD 2:1 MULTIPLEXER SY10E157 SY100E157 DESCRIPTION FEATURES ■ Individual select controls ■ Extended 100E VEE range of –4.2V to –5.5V The SY10/100E157 contain four 2:1 multiplexers with differential outputs. The output data are controlled by the individual Select (SEL) inputs. The individual select control makes the devices well suited for random logic designs. ■ ■ ■ ■ 550ps max. D to Output 800ps max. SEL to Output Internal 75KΩ input pull-down resistors Fully compatible with industry standard 10KH, 100K ECL levels ■ Available in 28-pin PLCC package VCCO 1 Q3 Q3 SEL3 NC D0a D3a D3b PIN CONFIGURATION BLOCK DIAGRAM Q0 MUX 25 24 23 22 21 20 19 Q0 0 SEL0 1 Q1 MUX 0 18 Q2 D2a SEL2 VEE SEL1 D1a 27 17 15 Q2 VCC Q1 14 Q1 3 13 4 12 Q0 Q0 D1b SEL1 28 2 5 SEL0 D0a Q2 MUX D2b 6 7 8 9 10 11 1 Q2 VCCO D2a 16 PLCC TOP VIEW J28-1 1 NC D1b Q1 26 NC D1a D2b D0b NC D0b 0 SEL2 D3a 1 Q3 MUX D3b Q3 0 PIN NAMES SEL3 Pin Function D0a – D3a Input Data a D0b – D3b Input Data b SEL0 – SEL3 Select Inputs Q0 – Q3 True Outputs Q0 – Q3 Inverted Outputs VCCO VCC to Output Rev.: D 1 Amendment: /2 Issue Date: May, 1998 SY10E157 SY100E157 Micrel TRUTH TABLE SEL Data H a L b DC ELECTRICAL CHARACTERISTICS VEE = VEE (Min.) to VEE (Max.); VCC = VCCO = GND TA = –40°C Symbol Parameter TA = 0°C Min.
