General Description
The EL7154C 3-state pin driver is particularly well suited for
ATE and level shifting applications The 4A peak drive capabil-
ity makes the EL7154C 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
n-channel device can turn off effectively when VL 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 VL to a moderate nega-
tive potential
