| EL7154C EL7154C High Speed Monolithic Pin Driver Features 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 impedance 2 5X Low quiescent current 5 mA Wide operating voltage 4 5V - 16V Isolated P-channel device Separate ground and VL pins 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 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 Applications Loaded circuit board testers Digital testers Level shifting below GND IGBT drivers CCD drivers Connection Diagram Ordering Information Part No Temp Range Pkg Outline EL7154CN b 40 C to a 85 C 8-Pin P-DIP MDP0031 EL7154CS b 40 C to a 85 C 8-Pin SOIC MDP0027 Nominal Operating Voltage Range Pin VL VDD -VL VH -VL VDD -VH VDD Min b3 Max 0 15 15 15 15 7154 -
