EL7156
High Performance Pin Driver
The EL7156 high performance pin
driver with 3-state is suited to many
ATE and level-shifting applications.
The 3.5A peak drive capability makes this part an excellent
choice when driving high capacitance loads.
The output pin OUT is connected to input pins V
H
or V
L
respectively, depending on the status of the IN pin. When the
OE pin is active low, the output is placed in the 3-state mode.
The isolation of the output FETs from the power supplies
enables V
H
and V
L
to be set independently, enabling level-
shifting to be implemented. Related to the EL7155, the
EL7156 adds a lower supply pin V
S
- and makes V
L
an
isolated and independent input. This feature adds
applications flexibility and improves switching response due
to the increased enhancement of the output FETs.
This pin driver has improved performance over existing pin
drivers. It is specifically designed to operate at voltages
down to 0V across the switch elements while maintaining
good speed and on-resistance characteristics.
Available in the 8-pin SO and 8-pin PDIP packages, the
EL7156 is specified for operation over the full -40C to
+85C temperature range.
