DescriptionThe AD53040 is a complete high speed pin driver designed foruse in digital or mixed-signal test systems. Combining a highspeed monolithic process with a unique surface mount package,this product attains superb electrical performance whilepreservingoptimum packaging densities and long-term reliability in anultrasmall 20-lead, SOP package with built-in heat sink.
Featuring unity gain programmable output levels of 3 V to+8 V, with output swing capability of less than 100 mV to 9 V,the AD53040 is designed to stimulate ECL, TTL and CMOSlogic families. The 500 MHz data rate capacity and matchedoutput impedance allows for real-time stimulation of thesedigital logic families. To test I/O devices, the pin driver canbe switched into a highimpedance state (Inhibit Mode), electricallyremoving the driver from the path. The pin driver leakagecurrent inhibit istypically 100 nA and output charge transferentering inhibit is typically less than 20 pC.
The AD53040 transition from HI/LO or to inhibit is controlledthrough the data and inhibit inputs. The input circuitry useshigh speed differential inputs with a common-mode range of± 3 V. This allows for direct interface to precision differentialECL timing or the simplicity of stimulating the pin driver from asingle ended TTL or CMOS logic source. The analog logic HI/LOinputs are equally easy to interface. Typically requiring 10 mA ofbias current, the AD53040 can be directly coupled to theoutput of a digital-to-analog converter.
The AD53040 is available in a 20-lead, SOP package with abuilt-in heat sink and is specified to operate over the ambientcommercial temperature range of 25 to +85.
