The EL7156 high performance pin driver with three-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 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 EL7156 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 and 8 Ld PDIP packages, the

EL7156 is specified for operation over the full -40°C to

+85°C temperature range.
