9099FMQB

Overview

The 9099FMQB is a J-K flip-flop manufactured by National Semiconductor, now part of Texas Instruments. It features two functional elements configured as master-slave triggered devices using DTL logic technology. The component operates within an ambient temperature range of -55°C to 125°C and draws a quiescent current of 28 mA. It is housed in a 14-pin ceramic dual in-line package (CDFP14) designed for through-hole mounting.

Feature Summary

• Master-slave triggered J-K flip-flop architecture
• DTL logic technology implementation
• Dual functional element configuration

Applications

• Digital data storage systems
• Sequential logic circuit design
• Industrial control applications requiring wide temperature operation

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific CDFP14 ceramic package matches your board layout requirements. Confirm that the 28 mA quiescent current aligns with your power budget constraints before finalizing procurement decisions.

Selection Notes

Select this component when a robust, high-temperature J-K flip-flop is required for legacy or industrial environments. The through-hole CDFP14 package dictates specific PCB mounting considerations. Evaluate the relatively high quiescent current against system power efficiency goals compared to modern CMOS alternatives.

Part Context

This device belongs to the family of discrete digital logic components produced under the National Semiconductor brand. These parts were widely used in mid-to-late 20th-century computing and industrial electronics. The transition to Texas Instruments has maintained the availability of these established logic families for specialized manufacturing needs.

Replacement Considerations

Cross-reference with other National Semiconductor/TI J-K flip-flops in the 54/74 series. Verify pin compatibility and electrical characteristics against equivalent parts from other manufacturers if redesigning the circuit board.
