1 tm file number 3544.3 hs-0546rh, HS-0547RH radiation hardened single 16/differential 8 channel cmos analog multiplexers with active overvoltage protection the hs-0546rh and HS-0547RH 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-0546rh and HS-0547RH 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-0546 is a 16 channel device and the hs-0547 is an 8 channel differential version. if input overvoltage protection is not needed, the hs-0506 and hs-0507 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 5962-95693. a ?hot-link? is provided on our homepage for downloading. http://www.intersil.com features ? electrically screened to smd # 5962-95693 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 switch analog signal range . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15v access time. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.0 s applications data acquisition systems control systems telemetry pinouts hs-0546rh gdip1-t28 (cerdip) or cdip2-t28 (sbdip) top view HS-0547RH gdip1-t28 (cerdip) or cdip2-t28 (sbdip) top view ordering information ordering number internal mkt. number temp. range ( o c) 5962d9569301v9a hs0-0546rh-q 25 5962d9569301vxa hs1-0546rh-q -55 to 125 5962d9569301vxc hs1b-0546rh-q -55 to 125 5962d9569302v9a hs0-0547rh-q 25 5962d9569302vxa hs1-0547rh-q -55 to 125 5962d9569302vxc hs1b-0547rh-q -55 to 125 v supply nc nc in 16 in 15 in 14 in 13 in 12 in 11 in 10 in 9 gnd v ref address a3 out in 8 in 7 in 6 in 5 in 3 in 1 enable address a0 address a1 address a0 -v supply in 4 in 2 28 27 26 25 24 23 22 21 20 19 18 17 16 15 1 2 3 4 5 6 7 8 9 10 11 12 13 14 +v supply out b nc in 8b in 7b in 6b in 5b in 4b in 3b in 2b in 1b gnd v ref nc out a in 8a in 7a in 6a in 5a in 3a in 1a enable address a0 address a1 address a2 -v supply in 4a in 2a 28 27 26 25 24 23 22 21 20 19 18 17 16 15 1 2 3 4 5 6 7 8 9 10 11 12 13 14 data sheet august 2001 tle - 6r s- 7r - ia- d- le if- n- 8 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
