The EL7158 high performance pin
driver with three-state is suited to
many ATE and level-shifting
applications. The 12A peak drive capability 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 three-state
mode. The isolation of the output FETs from the power
supplies enables VH and VL to be set independently,
enabling level-shifting to be implemented. Related to the
EL7155, the EL7158 adds a lower supply pin VS- and makes
VL 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 Ld SOIC package, the EL7158 is specified
for operation over the full -40°C to +85°C temperature range.
