74HCT221  
Dual non-retriggerable monostable multivibrator with reset  
Rev. 3 — 26 October 2016  
Product data sheet  
1. General description  
The 74HCT221 is a dual non-retriggerable monostable multivibrator. Each multivibrator  
features edge-triggered inputs (nA and nB), either of which can be used as an enable  
input. Pulse triggering occurs at a particular voltage level and is not directly related to the  
transition time of the input pulse. Schmitt-trigger input circuitry for the nB inputs allow  
jitter-free triggering from inputs with slow transition rates, providing the circuit with  
excellent noise immunity. Once triggered, the outputs (nQ, nQ) are independent of further  
transitions of nA and nB inputs. The output pulse width is defined by the following  
relationship: tW = 0.7 CEXT REXT The output pulses can be terminated by the active  
LOW reset inputs (nRD). Pulse width stability is achieved through internal compensation  
and is virtually independent of VCC and temperature. In most applications pulse stability  
will only be limited by the accuracy of the external timing components. Inputs include  
clamp diodes. This enables the use of current limiting resistors to interface inputs to  
voltages in excess of VCC  
.
2. Features and benefits  
Input levels:  
For 74HCT221: TTL level  
Pulse width variance is typically less than 5%  
Direct reset terminates output pulse  
Schmitt-trigger action on nB inputs  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Specified from 40 C to +85 C and from 40 C to +125 C
