High Speed, Monolithic Pin Driver
The EL7154 three-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. The 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 N-Channel 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.
