TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74HC123AP,TC74HC123AF

Dual Retriggerable Monostable Multivibrator

The TC74HC123A is a high speed CMOS MONOSTABLE

MULTIVIBRATOR fabricated with silicon gate C²MOS

technology.

TC74HC123AP

It achieves the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

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

input (positive edge). These inputs are valid for a slow rise/fall

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

device may also be triggered by using CLR input (positive

edge).

After triggering, the output stays in a MONOSTABLE state for

a time period determined by the external resistor and capacitor

(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).

TC74HC123AF

Limits for Cx and Rx are:

External capacitor, Cx: No limit

External resistor, Rx: 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.
