technology.

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

There are two trigger inputs, A input (positive edge input), and

B input (negative edge input). These inputs are valid for a slow

rise/fall time signal (t = t = 1 s) as they are schmitt trigger

inputs.

After triggering, the output stays in a MONOSTABLE state for

the time period determined by the external resistor and capacitor

(R , C ). A low level at CD input breaks this STABLE STATE.

In the MONOSTABLE state, if a new trigger is applied, it makes

the MONOSTABLE period longer (retrigger mode).

Limitations for C and R are as follows:

External capacitor C ........... No limitation

External resistor R .............. V

= 2.0 V more than 5 kΩ

≥ 3.0 V more than 1 kΩ

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.
