# CD4098BE

**Texas Instruments** · Monostable Multivibrators · DIP-16

CD4098BE from Texas Instruments, in a DIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CX1 | passive | External timing capacitor terminal for MONO1, electrically connected internally to pins 8 and 15 (VSS). |
| 2 | RXCX(1) | passive | Junction of external timing resistor RX and capacitor CX for MONO1 (RX minimum 5 kΩ, CX maximum 100 µF). |
| 3 | RESET(1) | input | Active-low reset input of MONO1 that immediately terminates the output pulse; tie to VDD if unused, or to VSS if the whole section is unused. |
| 4 | +TR(1) | input | Leading-edge trigger input of MONO1; tie to VSS if unused. |
| 5 | -TR(1) | input | Trailing-edge trigger input of MONO1; tie to VDD if unused. |
| 6 | Q1 | output | Buffered Q output of MONO1. |
| 7 | Q1̅ | output | Buffered complementary Q-bar output of MONO1. |
| 8 | VSS | power_in | Ground (negative supply) terminal, electrically connected internally to pins 1 and 15. |
| 9 | Q2̅ | output | Buffered complementary Q-bar output of MONO2. |
| 10 | Q2 | output | Buffered Q output of MONO2. |
| 11 | -TR(2) | input | Trailing-edge trigger input of MONO2; tie to VDD if unused. |
| 12 | +TR(2) | input | Leading-edge trigger input of MONO2; tie to VSS if unused. |
| 13 | RESET(2) | input | Active-low reset input of MONO2 that immediately terminates the output pulse; tie to VDD if unused, or to VSS if the whole section is unused. |
| 14 | RXCX(2) | passive | Junction of external timing resistor RX and capacitor CX for MONO2 (RX minimum 5 kΩ, CX maximum 100 µF). |
| 15 | CX2 | passive | External timing capacitor terminal for MONO2, electrically connected internally to pins 1 and 8 (VSS). |
| 16 | VDD | power_in | Positive supply terminal; recommended 3 V to 18 V, absolute maximum -0.5 V to +20 V referenced to VSS. |
