CD4098BM

Texas Instruments · Monostable Multivibrators · SOIC-16

CD4098BM from Texas Instruments, in a SOIC-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 monostable 1, electrically connected internally to terminals 8 and 15 (VSS).
2 Rx Cx (1) passive Junction of the external timing resistor Rx1 (to VDD) and capacitor Cx1 for monostable 1, with a minimum Rx of 5 kΩ and a maximum Cx of 100 µF.
3 RESET (1) input Active-low reset for monostable 1 that immediately terminates the output pulse or prevents pulses at power-on, and should be tied to VDD when unused.
4 +TR (1) input Leading-edge (positive) trigger input for monostable 1, which should be tied to VSS when unused.
5 -TR (1) input Trailing-edge (negative) trigger input for monostable 1, which should be tied to VDD when unused.
6 Q1 output Buffered Q output of monostable 1.
7 Q̄1 output Buffered complementary (Q-bar) output of monostable 1.
8 VSS power_in Negative supply terminal (ground), electrically connected internally to terminals 1 and 15.
9 Q̄2 output Buffered complementary (Q-bar) output of monostable 2.
10 Q2 output Buffered Q output of monostable 2.
11 -TR (2) input Trailing-edge (negative) trigger input for monostable 2, which should be tied to VDD when unused.
12 +TR (2) input Leading-edge (positive) trigger input for monostable 2, which should be tied to VSS when unused.
13 RESET (2) input Active-low reset for monostable 2 that immediately terminates the output pulse or prevents pulses at power-on, and should be tied to VDD when unused.
14 Rx Cx (2) passive Junction of the external timing resistor Rx2 (to VDD) and capacitor Cx2 for monostable 2, with a minimum Rx of 5 kΩ and a maximum Cx of 100 µF.
15 Cx2 passive External timing capacitor terminal for monostable 2, electrically connected internally to terminals 1 and 8 (VSS).
16 VDD power_in Positive supply terminal with a recommended range of 3 V to 18 V and an absolute maximum of -0.5 V to +20 V referenced to VSS.
