FN7283.1
EL7232
Dual Channel, High Speed, High Current
Line Driver w/3-State
The EL7232 3-state drivers are particularly well suited for
ATE and microprocessor based applications. The low
quiescent power dissipation makes this part attractive in
battery applications. The 2A peak drive capability, makes the
EL7232 an excellent choice when driving high speed
capacitive lines, as well. The input circuitry provides level
shifting from TTL levels to the supply rails. The EL7232 is
available in 8-pin PDIP and 8-lead SO packages.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with
both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
