7156C
General Description
The EL7156C high-performance pin driver with tri-state is suited to
many ATE and level-shifting applications. The 3.5A peak drive capa-
bility makes this part an excellent choice when driving high
capacitance loads.
The output pin OUT is connected to input pins VH or VL respectively,
depending on the status of the IN pin. When the OE pin is active low,
the output is placed in the tri-state mode. The isolation of the output
FETs from the power supplies enables VH and VL to be set indepen-
dently, enabling level-shifting to be implemented. Related to the
EL7155C, the EL7156C adds a lower supply pin V
S
- and makes VL
an isolated and independent input. This feature adds applications flex-
ibility 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 SOIC and 8-Pin PDIP packages, the EL7156C is
specified for operation over the -40C to +85C temperature range.
