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

device may also be triggered by using CLR input (positive

edge).

Features (Note)

•

The TC74HC221A 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

High speed: t

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

Pin and function compatible with 74LS221

Note:

External capacitor, Cx: No limit

External resistor, Rx: V
