EL7154
High Speed, Monolithic Pin Driver
The EL7154 3-state pin driver is particularly well suited for
ATE and level shifting applications. The 4A peak drive
capability, makes the EL7154 an excellent choice when
driving high speed capacitive lines.
The p-channel MOSFET is completely isolated from the
power supply, providing a high degree of flexibility. Pin (7)
can be grounded, and the output can be taken from pin (8)
when a "source follower" output is desired. Then n-channel
MOSFET has an isolated drain, but shares a common bus
with pre-drivers and level shifter circuits. This is necessary to
ensure that the nchannel device can turn off effectively when
V
L
goes below GND. In some power-FET and IGBT
applications, negative drive is desirable to insure effective
turn-off. The EL7154 can be used in these applications by
returning V
L
to a moderate negative potential.

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.
