The EL7158 is a high-performance, three-state pin driver from Intersil that is suited for many ATE and level-shifting applications. The 12A peak drive capability makes it an excellent choice when driving high capacitance loads. The output pin OUT is connected to input pins VH or VL, 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.
