1 Precision 8-Ch/ual 4-Ch Low Voltage Analog Multiplexers ESCRIPTION The G948, G949 uses BiCMOS wafer fabrication technology that allows the G948, G949 to operate on single and dual supplies. Single supply voltage ranges from 3 V to 1 V while dual supply operation is recommended with ± 3 V to ± 6 V. The G948 is an 8-channel single-ended analog multiplexer designed to connect one of eight inputs to a common output as determined by a 3-bit binary address (,, A ). The G949 is a dual 4-channel differential analog multiplexer designed to connect one of four differential inputs to a common dual output as determined by its -bit binary address (, ). Break-before-make switching action to protect against momentary crosstalk between adjacent channels. As a committed partner to the community and the environment, manufactures this product with lead (Pb)-free device terminations. The G948, G949 are offered in a QFN package that has a nickel-palladiumgold device terminations and is represented by the lead (Pb)-free -E4 suffix. The nickel-palladium-gold device terminations meet all the JEEC standards for reflow and MSL ratings. FEATURES.7 V to 1 V single supply or ± 3 V to ± 6 V dual supply operation Low on-resistance - R ON : 3.9 typ. Fast switching: t ON - 4 ns, t OFF - 4 ns Break-before-make guaranteed Low leakage TTL, CMOS, LV logic (3 V) compatible V ES protection (HBM) Material categorization: For definitions of compliance please see /doc?9991 BEFITS High accuracy Single and dual power rail capacity Wide operating voltage range Simple logic interface APPLICATIONS ata acquisition systems Battery operated equipment Portable test equipment Sample and hold circuits Communication systems SSL, SLAM Audio and video signal routing FUNCTIONAL BLOCK IAGRAM AN PIN CONFIGURATION G948 QFN16 S 1 A G949 QFN16 S 1b b a S 1 1 S 5 S b 1 1 S 1a GN 11 S 6 GN 11 S a S 3 3 S 3b 3 S 4 4 ecoder/river 9 S 7 S 4b 4 ecoder/river 9 S 3a S 8 Top View S 4a Top View S Rev., 7-May-13 1 THE PROUCTS ESCRIBE HEREIN AN THIS OCUMT ARE SUBJECT TO SPECIFIC ISCLAIMERS, SET FORTH AT /doc?9
