The HFA5253 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. Slew Rate Control pins

provide independent control over positive and negative slew

rate allowing the customer to optimize the pin driver speed

for their application. The output impedance is trimmed to

achieve a precision 50Ω source for impedance matching.

Two differential ECL/TTL compatible inputs control the

switching and the other controlling the output’s high-

impedance state. The HFA5253’s 800MHz data rate makes it

compatible with today’s high-speed VLSI test systems and

the +8V to -3V output swing satisfies the most stringent

testing requirements of all common logic families.

• Level Comparator/Translator

The HFA5253 is manufactured in Harris’ proprietary

complementary bipolar UHF-1 process.
