800MHz Monolithic Pin Driver
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 50Ω 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. The HFA5251’s 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. The HFA5251 is
offered in die form. Contact your local sales representative
for packaging options.
