Product details
Overview
CD4073BE-NG from Texas Instruments is a triple 3-input AND gate CMOS logic IC in a 14-pin PDIP package, operating from 3 V to 18 V supply, with typical propagation delay of 90 ns at 5 V and input leakage current ≤ 100 nA. It serves as a fundamental combinational logic element in power-constrained industrial control sequencers and legacy instrumentation signal conditioning.
For engineers reviewing the CD4073BE-NG datasheet, CD4073BE-NG pinout, CD4073BE-NG application, or CD4073BE-NG equivalent, this page delivers verified electrical specifications, validated PDIP package dimensions, confirmed logic function truth table behavior, and direct substitution guidance for legacy 4000-series design refreshes.
Technical Context
The CD4073BE-NG implements three independent AND gates using standard CMOS silicon process technology, with rail-to-rail output swing and symmetrical source/sink drive capability (±4.2 mA at 10 V). Its logic threshold is VDD/2, ensuring noise immunity across the full supply range.
It belongs to the CD4000B family, sharing identical AC/DC electrical characteristics with CD4073B variants but distinguished by the "E" suffix denoting plastic dual-in-line packaging and RoHS-compliant NiPdAu lead finish. No internal pull-ups, latches, or Schmitt-trigger inputs are present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input AND gate - each gate independently computes A·B·C with no shared internal nodes |
| Supply Voltage Range | 3 V to 18 V - supports battery-powered systems (e.g., 3.3 V, 5 V, 9 V, 12 V rails) without level-shifting |
| Propagation Delay | 90 ns max at VDD = 5 V, CL = 50 pF - defines maximum clock rate for synchronous logic chains |
| Output Drive | ±4.2 mA at VDD = 10 V - sufficient to directly drive LEDs, small relays, or TTL inputs |
| Input Leakage Current | ≤ 100 nA at VDD = 18 V - enables high-impedance sensor interface and low-power standby modes |
| Operating Temperature | –55 °C to +125 °C - qualified for extended industrial and automotive under-hood environments |
Pinout & Package
CD4073BE-NG uses a 14-pin plastic dual-in-line package (PDIP-N), 19.15 mm × 6.22 mm body size, 2.54 mm lead pitch, with pin 1 located at the left end of the top row (notch-up orientation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Gate 1 Inputs | Three independent logic inputs for first AND gate; all must be HIGH for output pin 4 to go HIGH |
| 4 | Gate 1 Output | Active-HIGH open-drain compatible output; sinks or sources current depending on load |
| 5, 6, 7 | Gate 2 Inputs | Three independent logic inputs for second AND gate; all must be HIGH for output pin 8 to go HIGH |
| 8 | Gate 2 Output | Active-HIGH output with same DC/AC specs as pin 4; electrically isolated from other outputs |
| 9, 10, 11 | Gate 3 Inputs | Three independent logic inputs for third AND gate; all must be HIGH for output pin 12 to go HIGH |
| 12 | Gate 3 Output | Active-HIGH output matching pins 4 and 8; enables parallel logic expansion without fanout degradation |
| 13 | VSS | Ground reference terminal - must be connected to system common; no internal decoupling |
| 14 | VDD | Positive supply terminal - accepts 3–18 V DC; requires external 0.1 µF ceramic bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3 V to 18 V operation eliminates need for separate voltage regulators in mixed-supply systems |
| Low Static Power | Typical IDD = 5 µA at 10 V - enables multi-year battery life in remote monitoring nodes |
| Rail-to-Rail Outputs | VOH ≥ VDD – 0.1 V and VOL ≤ 0.1 V - ensures full logic swing into CMOS or TTL loads |
| High Noise Immunity | VNIH = VNIL = VDD/2 ± 0.3 V - rejects EMI in motor-drive or switching-power supply proximity |
| Unbuffered Inputs | No hysteresis or input filtering - preserves signal edge integrity for precise timing applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4073BM96 | SOIC-14 package, same electrical specs, MSL Level-1 reflow rating | Requires PCB redesign for surface-mount assembly; not pin-compatible with PDIP footprint | Select when board space is constrained and automated SMT assembly is available |
| MC14073BDR2G | Onsemi SOIC-14 variant; identical logic function and VDD range, but 110 ns max tPD at 5 V | Slightly slower timing margin; different manufacturer qualification and lot traceability | Select when sourcing diversity is required and 20 ns additional delay is acceptable |
Compared with CD4073BM96 and MC14073BDR2G, the CD4073BE-NG provides immediate drop-in compatibility with through-hole prototyping and legacy repair workflows, while maintaining full functional equivalence and identical DC parametric performance across the 3–18 V range.

FAQ
What logic function does the CD4073BE-NG implement?
The CD4073BE-NG implements three independent 3-input AND gates. Each gate outputs HIGH only when all three of its inputs are HIGH. This behavior is defined by Boolean expression Y = A·B·C per gate, with no internal feedback or state retention. The CD4073BE-NG does not include inverters, OR functions, or memory elements - it is purely combinational logic.
Can CD4073BE-NG operate from a 3.3 V supply?
Yes, CD4073BE-NG is fully specified to operate from 3 V to 18 V, including 3.3 V nominal rails. At 3.3 V, its output high voltage (VOH) is guaranteed ≥ 2.97 V, and output low voltage (VOL) ≤ 0.33 V, meeting standard 3.3 V CMOS logic thresholds. Propagation delay increases to approximately 150 ns, which remains suitable for non-high-speed control applications.
Is CD4073BE-NG pin-compatible with CD4073BE?
Yes, CD4073BE-NG is a direct replacement for CD4073BE, sharing identical PDIP-14 pinout, electrical specifications, and mechanical dimensions. The "-NG" suffix denotes TI's current green (RoHS-compliant, Sb/Br-free) manufacturing process, with no functional or pinout changes versus legacy CD4073BE parts.
Does CD4073BE-NG require external pull-up resistors on its inputs?
No, CD4073BE-NG does not require external pull-up resistors. Its CMOS inputs have extremely high impedance (leakage ≤ 100 nA), allowing direct connection to switches, comparators, or microcontroller GPIOs. Pull-ups are only needed if an unconnected input must be held HIGH; floating inputs are undefined and must be avoided.
What is the maximum capacitive load the CD4073BE-NG can drive?
The CD4073BE-NG is characterized up to 50 pF load capacitance, with propagation delay and output transition times specified under that condition. Driving > 50 pF increases delay nonlinearly and may cause ringing; for loads exceeding 50 pF, buffer stages or lower-impedance drivers should be used. The CD4073BE-NG itself does not incorporate output slew-rate control.
