SN54120

The SN54120 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 inputs is not cirtical and the asverse effects of contact-bounce of a manual input are eliminated.

Features of the SN54120 are:(1)generates either a singele pulse or train of pulses synchronized with control functions; (2)ideal for implementing sync-control circuits similar to those used in oscillosco pes; (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 eliminiate need for external components; (6)diode-clamped inputs simlify system design.

The absolute maximum ratings of the SN54120 can be summarized as:(1)Supply voltage range, VCC:7 V; (2)Input voltage:5.5 V; (3)interemitter voltage:5.5 (4)Storage temperature range:-65°C to 150°C;(5)operating free-air temperature range:-55 to125.

The electrical characteristics(Ta=25) of the SN54120 can be summarized as:(1)VIK:-1.5V MAX; (2)VOL:0.2V TYP 0.4V MAX; (3)II:1mA;(4)IOS:-35mA MIN -90mA MAX; (5)ICC:51mA TYP 90mA MAX;(6)VOH:2.4V MIN 3.4V MAX.If you want to know more information such as the electrical characteristics of SN54120,please download the datasheet in www.seekdatasheet.com .
