SN74120N

The SN74120N is one of the SN74120 series.The SN74120N monolithic pulse synchronizers are designed to synchronize an asynchronous or manual signal with a system clock.Reliable response is ensured as the input signals are latched up;therefore duration of logic input is not critical and the asverse effects of contact-bounce of a manual input are eliminated.

Features of the SN74120N are:(1)generates either a single pulse or train of pulses synchronized with control functions ; (2)ideal for implementing sync-control circuits similar to those used in oscilloscopers; (3)latched operation ensures that outputs drive system clock lines directly; (4)internal input pull-up resistors eliminate need for external components ; (5)diode-clamped inputs sumplify system design; (6)typical propagation delays:9 nanoseconds through one level;16 nanoseconds through two levels.

The absolute maximum ratings of the SN74120N can be summarized as:(1)supply voltage,VCC:7V; (2)input voltage:5.5V; (3)operating free-air temperature range:0 to 70; (4)storage temperature range:-65 to 150.

The electrical characteristics(Ta=25) of the SN74120N can be summarized as:(1)VIK:-1.5V; (2)VOH:2.4V MIN 3.4V TYP; (3)II:1mA; (4)ICC:51mA TYP 90mA MAX.If you want to know more information such as the electrical characteristics of SN74120N ,please download the datasheet in www.seekdatasheet.com .
