File Number 3689.4
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 50鈩?source for impedance
matching. Two differential ECL/TTL compatible inputs control
the operation of the HFA5251, one controlling the
V

LOW
switching and the other controlling the output鈥檚
high-impedance state. The HFA5251鈥檚 800MHz data rate
makes it compatible with today鈥檚 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鈥檚 proprietary
complementary bipolar UHF-1 process. The HFA5251 is
offered in die form. Contact your local sales representative
for packaging options.
