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

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.

• Pattern Generators

• Pulse Generators

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.
