3 STATE/ PUSH-PULL INPUT
The input 3st/Pp is instead intended for a digital
incoming signal. It has an internal threshold set at
1.26V; an internal bias circuit (10
μ
A typical) simu-
lates a high level (three-state) if the pin is discon-
nected.
THE SWITCHING OF THE OUTPUT STAGE
The cross conduction of the two transistors of an
output stage of the L6374 would be significantly
noisy, because the transistors here can carry
peak currents in excess of 100mA, and even
more in the few nanoseconds before the current
limiting circuits are reallyeffective.
Consequently the device has been designed so
as to avoid such cross conduction. At every
switching transition, first of all the transistor in
conduction is turned off. Then, after a safe inter-
val of around 200ns, the other transistor is turned
on.
When analyzing the switching cycle, and the as-
sociated switching times, it is useful to identify
somesubsequentphases:
- delay from the input pin to the output reaction;
- off transitionin the output stage;
- dead time;
- on transitionin the output stage.
Figure 4 helps understand such sequence. In
