High Speed, Four Channel Power Features
MOSFET Drivers • Excellent response times
The EL7412 contains (4) high
• Matched rise and fall times
performance matched drivers. These
very high speed drivers are capable of • Reduced clock skew
delivering peak currents of 2.0 amps into highly capacitive • Low output impedance
loads and are ideally suited for “Full bridge' and ultrasound
applications. The high speed performance is achieved by • Low input capacitance
means of a proprietary “Turbo-Driver' circuit that speeds up • High noise immunity
input stages by tapping the wider voltage swing at the
• Improved clocking rate
output. Improved speed and drive capability are enhanced
by matched rise and fall delay times. The matched delays • Low supply current
maintain the integrity of input-to-output pulse-widths to • Wide operating voltage range
reduce timing errors and clock skew problems. This
improved performance is accompanied by a 10 fold Applications
reduction in supply currents over bipolar drivers, yet without
the delay time problems commonly associated with CMOS • Full bridge drivers
devices. Dynamic switching losses are minimized with non- • Clock/line drivers
overlapped drive techniques.
