1 tm file number 3543.4 hs-0548rh, HS-0549RH radiation hardened single 8/differential 4 channel cmos analog multiplexers with active overvoltage protection the hs-0548rh and HS-0549RH are radiation hardened analog multiplexers with active overvoltage protection and guaranteed r on matching. analog input levels may greatly exceed either power supply without damaging the device or disturbing the signal path of other channels. active protection circuitry assures that signal fidelity is maintained even under fault conditions that would destroy other multiplexers. analog inputs can withstand constant 70v peak-to-peak levels with 15v supplies and digital inputs will sustain continuous faults up to 4v greater than either supply. in addition, signal sources are protected from short circuiting should multiplexer supply loss occur: each input presents 1k ? of resistance under this condition. these features make the hs-0548rh and HS-0549RH ideal for use in systems where the analog inputs originate from external equipment or separately powered circuitry. both devices are fabricated with 44v dielectrically isolated cmos technology. the hs-0548 is an 8 channel device and the hs-0549 is a 4 channel differential version. if input overvoltage protection is not needed, the hs-0508 and hs-509 multiplexers are recommended. specifications for rad hard qml devices are controlled by the defense supply center in columbus (dscc). the smd numbers listed here must be used when ordering. detailed electrical specifications for these devices are contained in smd 5962-95694. a ?hot-link? is provided on our homepage for downloading. http://www.intersil.com features ? electrically screened to smd # 5962-95694 qml qualified per mil-prf-38535 requirements gamma dose . . . . . . . . . . . . . . . . . . . . . . 1 x 10 4 rad(si) no latch-up no channel interaction during overvoltage guaranteed r on matching maximum power supply . . . . . . . . . . . . . . . . . . . . . . 44v break-before-make switching analog signal range . . . . . . . . . . . . . . . . . . . . . . . . 15v access time. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.0 s applications data acquisition systems control systems telemetry pinouts hs-0548rh gdip1-t16 (cerdip) or cdip2-t16 (sbdip) top view HS-0549RH gdip1-t16 (cerdip) or cdip2-t16 (sbdip) top view ordering information ordering number internal mkt. number temp. range ( o c) 5962d9569401vea hs1-0548rh-q -55 to 125 5962d9569401vec hs1b-0548rh-q -55 to 125 5962d9569402vea hs1-0549rh-q -55 to 125 5962d9569402vec hs1b-0549rh-q -55 to 125 14 15 16 9 13 12 11 10 1 2 3 4 5 7 6 8 ao enable -v supply in 1 in 2 in 3 out in 4 a1 gnd +v supply in 5 in 6 in 7 in 8 a2 14 15 16 9 13 12 11 10 1 2 3 4 5 7 6 8 a0 enable -v supply in 1a in 2a in 3a outa in 4a a1 +v supply in 1b in 2b in 3b in 4b out b gnd data sheet august 2001 tle - 8r s- 9r - ia- d- le if- n- 4 n- os - ti- - ve r- - ec- ) tho caution: these devices are sensitive to electrostatic discharge; follow proper ic handling procedures. 1-888-intersil or 321-724-7143 | intersil and design is a trademark of intersil americas inc. copyright ? intersil americas inc. 2001, all rights reserved
