800MHz, Ultra High-Speed Monolithic Pin
Driver
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
operation of the HFA5253, one controlling the V_HIGH/V_LOW
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.
The HFA5253 is manufactured in Harris’ proprietary
complementary bipolar UHF-1 process.
