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
# Wide operating voltageÐ
4.5V–16V
n-channel device can turn off effectively when V goes below
L
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 to a moderate nega-
L
tive potential.
