CD4098BE Texas Instruments Integrated Circuit (Dual-In-Line Packages) In Stock
Texas Instruments CD4098BE is a dual retriggerable CMOS monostable multivibrator with independent timing for each channel, operating from 3 V to 18 V. Each one-shot accepts positive or negative edge triggering and sets pulse width via external resistor and capacitor. Available from stock worldwide in a 16-pin PDIP package.

What are the key features of CD4098BE?
- Dual independent retriggerable monostable channels allow two separate timed pulse outputs from a single 16-pin IC
- Positive and negative edge trigger inputs on each channel provide flexible interfacing to rising or falling signal edges
- 3 V to 18 V wide supply range is compatible with 3.3 V, 5 V, and 12 V CMOS logic families without additional level translation
- External R-C timing network gives pulse width programmable from microseconds to seconds for flexible delay generation
What is CD4098BE used for?
The CD4098BE is used in pulse-width generation, timing-delay circuits, and switch-debounce applications across industrial control panels, laboratory instrumentation, and consumer electronics. Its retriggerable operation makes it ideal for generating watchdog reset pulses or one-shot timers that extend their output for as long as input events continue. The 16-pin PDIP package suits breadboard prototyping and through-hole production boards where socket-mounting of timing ICs is preferred.

Frequently Asked Questions
How is the output pulse width of CD4098BE set and what component values are required for a 1 ms pulse?
Pulse width is determined by an external resistor and capacitor connected to the timing pins: T_w ≈ 0.5 × R × C. For a 1 ms output pulse, a 100 kΩ resistor with a 20 nF capacitor gives approximately 1 ms. The resistor should be in the range of 10 kΩ to 10 MΩ for reliable oscillation.
What does retriggerable mean for CD4098BE and how does it extend pulse duration in a motion-detection alarm?
Retriggerable means a new trigger edge while the output is already high restarts the timing interval from zero. In a motion detector, each detected movement extends the alarm output pulse by the full programmed period. For a 5-second pulse width, continuous motion keeps the output active indefinitely without external logic, unlike non-retriggerable one-shots.
Can both channels of CD4098BE be cascaded for a two-stage sequential delay, and what timing accuracy is achievable?
Yes. The Q output of channel 1 can drive the trigger input of channel 2, creating a sequential delay chain. Each stage's timing accuracy depends on the R-C tolerance; using 1% resistors and 5% capacitors typically yields better than 6% pulse-width accuracy across the 3 V to 18 V supply range and -40°C to 85°C temperature range.
For a 5 V logic system, does CD4098BE interface directly with TTL or 3.3 V CMOS without additional circuitry?
At 5 V supply the CD4098BE input thresholds are approximately 1.5 V, making it directly compatible with 5 V TTL outputs and 3.3 V CMOS outputs. The output drive is 4 mA sink at 5 V, adequate to drive CMOS loads at 50 pF load capacitance, eliminating level-translation components in standard 5 V mixed-logic boards.
