SN74120

The SN74120 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 adverse effects of contact-bounce of a manual input are eliminated.

Features of the SN74120 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 ussed in oscilloscopes; (3)latched operation ensures that output pulses are not clipped; (4)high-fan-out complementary outputs drive system clock lines directly ; (5)internal input pull-up resistors eliminate need for external components; (6)diode-clamped inputs simplify system design; (7)typical propagation delays:9 nanoseconds through one level;16 nanoseconds through two levels.

The absolute maximum ratings of the SN74120 can be summarized as:(1)supply voltage,VCC:7V; (2)input voltage:5.5V; (3)interemitter voltage:5.5V; (4)operating free-air temperature range:0 to70; (5)storage temperature range:-65 to 150.

The electrical characteristics(Ta=25) of the SN74120 can be summarized as:(1)VIH:2V MIN; (2)VIL:0.8V MAX; (3)VIK:-1.5V MAX;(4)VOL:0.2V TYP 0.4V MAX; (5)ICC:51mA TYP 90mA MAX.If you want to know more information such as the electrical characteristics of SN74120 ,please download the datasheet in www.seekdatasheet.com .
