Overview
Description
The EL7154 three-state pin driver is particularly well suited for ATE and level shifting applications. The 4A peak drive capability, makes the EL7154 an excellent choice when driving High-Speed capacitive lines. The P-Channel MOSFET is completely isolated from the power supply, providing a high degree of flexibility. Pin (7) can be grounded, and the output can be taken from pin (8) when a source follower output is desired. The N-Channel MOSFET has an isolated drain, but shares a common bus with pre-drivers and level shifter circuits. This is necessary to ensure that the N-Channel device can turn off effectively when VL goes below GND. In some power-FET and IGBT applications, negative drive is desirable to insure effective turn-off. The EL7154 can be used in these applications by returning VL to a moderate negative potential.
