Transcription

1 Single 4 x and Dual 2 x Multiplexers DG944, DG945 DESRIPTION The DG944, a single 4 to multiplexer, and the DG945, a dual 2 x multiplexer, are monolithic MOS analog devices designed for high performance low voltage operation. ombining low power, high speed, low on-resistance and small physical size, the DG944 and DG945 are ideal for portable and battery powered applications requiring high performance and efficient use of board space. Both the DG944 and DG945 are built on s low voltage BD-5 process. Minimum ESD protection, per Method 305.7, is 00 V. An epitaxial layer prevents latchup. Break-before-make is guaranteed for DG945. FEATURES Low voltage operation (+ 2.7 V to + 2 V) Low on-resistance - R DS (on): 4 Low power consumption TTL compatible ESD protection > 00 V (method 305.7) Available in TSSOP- (aka MSOP-) ompliant to RoHS Directive 02/95/E BENEFITS High accuracy Simple logic interface Reduce board space APPLIATIONS Battery operated systems Portable test equipment Sample and hold circuits ellular phones ommunication systems Networking equipment FUNTIONAL BLOK DIAGRAM AND P ONFIGURATION DG944DQ NO 2 NO OM NO 3 8 NO 0 EN 4 Logic 7 A A DG945DQ NO OM 2 9 OM 2 N 3 8 NO 2 EN 4 7 N 2 5 Logic 6 A 0 EN A A 0 On Switch X X None NO NO 0 0 NO 2 0 NO 3 X = Do not care EN A 0 On Switch X None 0 0 N N 2 0 NO NO 2 X = Do not care ORDERG FORMATION Temp Range Package Part Number - 40 to 85 MSOP- DG944DQ-T-E3 DG945DQ-T-E3 Document Number: 7766 S-0984-Rev.
