EL7232

Data Sheet December 14, 2007

Dual Channel, High Speed, High Current
Line Driver with 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 Ld PDIP and 8 Ld SO packages.

*Please refer to TB347 for details on reel specifications.
**Pb-free PDIPs can be used for through hole wave solder
processing only. They are not intended for use in Reflow solder
processing applications.
NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate PLUS ANNEAL - e3 termination
finish, which is 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.
