CD4069UB

Texas Instruments · Logic Gate · SOIC-14

The CD4069UB contains six independent inverters in the 4000B CMOS family. The unbuffered (UB) design gives a single inversion stage, which makes it handy not just for logic inversion but as a linear gain element in RC and crystal oscillators. It runs from 3 V to 18 V.

Pinout

Pin Name Type Function
1 A input Inverter A input (channel 1). CMOS logic input, VIL ≤ 1 V @ VDD=5 V, VIH ≥ 4 V @ VDD=5 V. Input current typically ±10 pA @ 25 °C, ±1 µA max over full temperature range. Input capacitance 10 pF typ, 15 pF max.
2 G output Inverter A output (G = NOT A). CMOS push-pull output. VOH ≥ VDD − 0.05 V, VOL ≤ 0.05 V. Sinks ~0.51 mA typ (VO=0.4 V, VDD=5 V); sources ~-0.51 mA typ (VO=4.6 V, VDD=5 V). Dissipation ≤100 mW per output transistor.
3 B input Inverter B input (channel 2). CMOS logic input; same electrical thresholds as pin 1.
4 H output Inverter B output (H = NOT B). CMOS push-pull output; same drive characteristics as pin 2.
5 C input Inverter C input (channel 3). CMOS logic input; same electrical thresholds as pin 1.
6 I output Inverter C output (I = NOT C). CMOS push-pull output; same drive characteristics as pin 2.
7 VSS power_in Negative supply / ground reference. All voltages referenced to VSS. Typically tied to 0 V.
8 J output Inverter D output (J = NOT D). CMOS push-pull output; same drive characteristics as pin 2.
9 D input Inverter D input (channel 4). CMOS logic input; same electrical thresholds as pin 1.
10 K output Inverter E output (K = NOT E). CMOS push-pull output; same drive characteristics as pin 2.
11 E input Inverter E input (channel 5). CMOS logic input; same electrical thresholds as pin 1.
12 L output Inverter F output (L = NOT F). CMOS push-pull output; same drive characteristics as pin 2.
13 F input Inverter F input (channel 6). CMOS logic input; same electrical thresholds as pin 1.
14 VDD power_in Positive supply. Recommended operating range 3 V to 18 V (absolute max 20 V). Bypass with a 100 nF ceramic close to the pin.
