•Current Mirrors
•Multipliers
The THAT 300, 320 and 340 are largegeometry, 4-transistor, monolithic NPN and/or PNParrays. They exhibit both high speed and low noise,with excellent parameter matching between transis-tors of the same gender. Typical base-spreadingresistance is 25 Ω for the PNP devices (30 Ω for thelow-gain NPNs), so their resulting voltage noise isunder 1 nV/√Hz. This makes the 300 series ideallysuited for low-noise amplifier input stages, log ampli-fiers, and many other applications. The four-NPNtransistor array is available in versions selected forhfe with minimums of 150 (300A) or 300 (300B).
Fabricated in a dielectrically isolated, comple-mentary bipolar process, each transistor is electri-cally insulated from the others by a layer ofinsulating oxide (not the reverse-biased PN junctions
used in conventional arrays). As a result, they exhibitinter-device crosstalk and DC isolation similar tothat of discrete transistors. The resulting lowcollector-to-substrate capacitance produces a typicalNPN fT of 350 MHz (325 MHz for the PNPs).Substrate biasing is not required for normal opera-tion, though the substrate should be ac-grounded tooptimize speed and minimize crosstalk.
An eight-transistor bare-die array with similarperformance characteristics (the THAT 380G) is alsoavailable from THAT Corporation. Please contact usdirectly or through your local distributor for moreinformation. Military-grade temperature rangepackages are available from TT Semiconductor (seewww.ttsemiconductor.com for more information).

The THAT 300, 320 and 340 are available in 14-pinPDIP and 14-pin surface mount (SOIC) packages.Package dimensions are shown below.
The 300-series packages are entirely lead-free. Thelead-frames are copper, plated with successive layers ofnickel, palladium, and gold. This approach makes itpossible to solder these devices using lead-free and lead-bearing solders.
Neither the lead-frames nor the plastic moldcompounds used in the 300-series contains any hazard-ous substances as specified in the European Union'sDirective on the Restriction of the Use of Certain Hazard-ous Substances in Electrical and Electronic Equipment2002/95/EG of January 27, 2003. The surface-mountpackage is suitable for use in a 100% tin solder process.
