EL7154C EL7154C High Speed, Monolithic Pin Driver Features General Description # # # # # # # # # # The EL7154C 3-state pin driver is particularly well suited for ATE and level shifting applications. The 4A peak drive capability, makes the EL7154C an excellent choice when driving high speed capacitive lines. Comparatively low cost 3-State output 3V and 5V Input compatible Clocking speeds up to 10 MHz 20 ns Switching/delay time 4A Peak drive Isolated drains Low output impedanceÐ2.5X Low quiescent currentÐ5 mA Wide operating voltageÐ 4.5V – 16V # Isolated P-channel device # Separate ground and VL pins 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. Then 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.
