Detailed Description

CMOS hex inverter (CD4000 family), DIP-14 through-hole package. Six independent inverters per chip. Wide supply range, low power, high noise immunity. Suitable for general digital inversion, level shifting within CMOS rails, and building oscillator or waveform-shaping circuits when used per datasheet guidance.

Key Features

Six inverters in one IC (hex inverter)

CMOS technology with very low static power

Wide supply voltage: 3 V to 18 V

High noise immunity (CMOS thresholds as a fraction of VDD)

Rail-to-rail logic levels (VOH ≈ VDD, VOL ≈ VSS within limits)

Broad operating temperature range (see datasheet for grade specifics)

Standard DIP-14 footprint for easy prototyping and repair

Compatible with CD4000 ecosystem logic

Key Advantages

Simple, robust building block for inversion and signal conditioning

Operates over battery and industrial rails without level translators

Low quiescent current saves power

Through-hole package is easy to hand-solder and socket

Mature, widely available family with long-term support

Flexible for discrete oscillator and timing circuits using RC networks (refer to datasheet application notes)

Packaging

Type: DIP-14 (through-hole), JEDEC 0.3-inch (7.62 mm) body width

Material: Molded epoxy package; copper alloy leads with Pb-free finish (varies by lot; check datasheet/label)

Size (typical): body width ~7.62 mm, length ~19.3–19.7 mm, height ~3.0–4.0 mm

Pin pitch: 2.54 mm; 7 pins per side

Pin configuration (typical for CD4069, confirm in datasheet):

- Pin 1: 1A (input)

- Pin 2: 1Y (output)

- Pin 3: 2A

- Pin 4: 2Y

- Pin 5: 3A

- Pin 6: 3Y

- Pin 7: VSS (GND)

- Pin 8: 4Y

- Pin 9: 4A

- Pin 10: 5Y

- Pin 11: 5A

- Pin 12: 6Y

- Pin 13: 6A

- Pin 14: VDD (positive supply)

Thermal characteristics: DIP θJA typically ~85–100 °C/W on a standard board (exact value depends on layout)

Electrical properties (family-typical, see datasheet for exact specs):

- Supply voltage: 3–18 V

- Input thresholds scale with VDD (CMOS logic)

- Output current capability: small-signal CMOS, a few mA typical (higher at larger VDD)

- Propagation delay: decreases as VDD increases (hundreds of ns at 5 V, tens of ns at 10–15 V)

Lifecycle

Status: Active and widely used in general-purpose CMOS logic
