General Description
The EL7412C contains (4) high performance matched drivers
These very high speed drivers are capable of delivering peak
currents of 2 0 amps into highly capacitive loads and are ideally
suited for ``Full bridge'' and ultrasound applications The high
speed performance is achieved by means of a proprietary ``Tur-
bo-Driver'' circuit that speeds up input stages by tapping the
wider voltage swing at the output Improved speed and drive
capability are enhanced by matched rise and fall delay times
The matched delays maintain the integrity of input-to-output
pulse-widths to reduce timing errors and clock skew problems
This improved performance is accompanied by a 10 fold reduc-
tion in supply currents over bipolar drivers yet without the
delay time problems commonly associated with CMOS devices
Dynamic switching losses are minimized with non-overlapped
drive techniques
