heavy loads, as they are specified to deliver only
200μA for TTL compatibility. If an application needs
output buffering, use 74LS74s or 74ALS541s as
required.
Applications Information
Figure 5 depicts a typical application circuit containing
a single-ended to differential converter. The internal ref-
erence provides a +2.25V output for level shifting. The
input is buffered and then split to a voltage follower and
inverter. The op amps are followed by a lowpass filter
to remove some of the wideband noise associated with
high-speed op amps. In this application, the amplifier
outputs are directly coupled to the inputs. This configura-
tion can also be modified for AC-coupled applications.
The MAX1425 includes a DC level-shifting circuit internal
to the part, allowing for AC-coupled applications. The
level-shifting circuit is shown in Figure 6.
The circuit in Figure 6 can accept a 1Vp-p maximum
input voltage. With a maximum clock frequency of
20MHz, use 50
termination to minimize reflections.
Buffer the digital outputs with a low-cost, high-speed,
