General Description
The EL7154C 3-state pin driver is particularly well suited for
ATE and level shifting applications. The 4A peak drive capability, 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 V
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.

All parameters having Min/Max specifications are guaranteed. The Test Level column indicates the specific device testing actually
performed during production and Quality inspection. Elantec performs most electrical tests using modern high-speed automatic test
equipment, specifically the LTX77 Series system. Unless otherwise noted, all tests are pulsed tests, therefore T
