The MC10198 is a retriggerable monostable multivibrator. T wo enable inputs
permit triggering on any combination of positive or negative edges as shown in
the accompanying table. The trigger input is buffered by Schmitt triggers
making it insensitive to input rise and fall times.
The pulse width is controlled by an external capacitor and resistor. The
resistor sets a current which is the linear discharge rate of the capacitor. Also,
the pulse width can be controlled by an external current source or voltage (see
applications information).
For high–speed response with minimum delay, a hi–speed input is also
provided. This input bypasses the internal Schmitt triggers and the output
responds within 2 nanoseconds typically.
Output logic and threshold levels are standard MECL 10,000. Test
conditions are per Table 2. Each “Precondition” referred to in Table 2 is per the
sequence of Table 1.
