CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

The HFA5251 is a very high speed monolithic pin driver solution for high performance test systems. The device will switch at high data rates between two input voltage levels providing variable amplitude pulses. The output impedance is trimmed to achieve a precision 50 source for impedance matching. Two differential ECL/TTL compatible inputs control the operation of the HFA5251, one controlling the V_HIGH/V_LOW switching and the other controlling the output's high-impedance state. Its 800MHz data rate makes it compatible with today's high-speed VLSI test systems and the +7V to -2V output swing allows testing of all common logic families.

The HFA5251 is manufactured in Intersil's proprietary complementary bipolar UHF-1 process. It is offered in die form. Contact your local sales representative for packaging options.
