Combining a high speed monolithic process with a unique surface mount package, this product attains superb electrical performance while preserving optimum packaging densities and long-term reliability in an ultrasmall 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 CMOS logic families. The 500 MHz data rate capacity and matched output impedance allows for real-time stimulation of these digital logic families. To test I/O devices, the pin driver can be switched into a high impedance state (Inhibit Mode), electrically removing the driver...
