PRODUCT DESCRIPTION
The AD53020 is a four-channel delay line designed for use in automatic test equipment and digital logic systems. High speed bipolar transistors and a 44-lead plastic PLCC package with internal heat spreader provide high frequency performance at a minimum of space, cost and power dissipation.
Featuring full pin compatibility and functional equivalence to the BT624, the AD53020 offers independent analog control of positive and negative edges with five delay ranges. The AD53020 offers attractive performance with optimized power dissipation and linear delay vs. program voltage control. This device is also very stable over operating conditions and has very low jitter.
