SN54109

The SN54109 is a devices contain two independent J-K positive-edge-triggered flip-flops.A low level at the preset or clear inputs sets or resets the outputs regardless of the levels of the other inputs.When preset and clear are in-active(high),data at the J and K inputs meeting the setup time requirements are transferrend to the outputs on the positive-going edge of the clock pulse.

Features of the SN54109 are:(1)package options include plastic"small outline"packages,ceramic chip carriers and flat packaegs,ceramic chip carriers and flat packages,and plastic and ceramic DIPs; (2)dependable texas instruments quality and relability.

The absolute maximum ratings of the SN54109 can be summarized as:(1)supply voltage,VCC:7V; (2)input voltage:5.5V; (3)operating free-air temperature range:-55 to 125; (4)storage temperature range:-65 to 150.

The electrical characteristics(Ta=25) of the SN54109 can be summarized as:(1)VIK:-1.5V MAX; (2)VOL:0.2V TYP 0.4V MAX; (3)II:1mA;(4)IOS:-30mA MIN -85mA MAX; (5)ICC:9mA TYP 15mA MAX;(6)VOH:2.4V MIN 3.4V MAX.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
