time signal (tr = tf = 1 s) as they are schmitt trigger inputs. This

device may also be triggered by using CLR input (positive

edge).

(Rx, Cx ). A low level at the CLR input breaks this state. In the

MONOSTABLE state, if a new trigger is applied, it extends the

MONOSTABLE period (retrigger mode).

Features (Note)

•

The TC74HC123A is a high speed CMOS MONOSTABLE

It achieves the high speed operation similar to equivalent

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

After triggering, the output stays in a MONOSTABLE state for

Limits for Cx and Rx are:

All inputs are equipped with protection circuits against static

Low power dissipation

High noise immunity: V

Output drive capability: 10 LSTTL loads

Symmetrical output impedance: |I

Balanced propagation delays: t

Wide operating voltage range: V
