Product details
Overview
CD4023BF from Texas Instruments is a triple 3-input NAND gate CMOS logic IC in a hermetic 14-lead ceramic dual-in-line package (CDIP), operating across –55°C to +125°C, with supply voltage range 3 V to 18 V, and propagation delay of 90 ns at 5 V. It serves as a core combinational logic element in radiation-tolerant, high-reliability control circuits for aerospace and industrial systems.
For engineers reviewing the CD4023BF datasheet, CD4023BF pinout, CD4023BF application, or CD4023BF equivalent, this page delivers verified package mapping, confirmed electrical specs, validated pin functions, and two rigorously cross-checked alternative parts - all tied explicitly to the CD4023BF ordering variant with F3A suffix and SNPB lead finish.
Technical Context
The CD4023BF implements three independent 3-input NAND gates using standard CMOS silicon-gate technology, delivering rail-to-rail output swing and near-zero static current draw. Its input threshold is VDD/2, enabling direct interfacing with other CD4000-series devices without level-shifting.
Designed for military-grade reliability, the CD4023BF features hermetic ceramic packaging with glass-frit sealing, rated for operation up to 125°C ambient and storage down to –65°C. It meets MIL-STD-883 requirements for mechanical shock, vibration, and thermal cycling when tested per Method 2001/2002/2010.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input NAND gate - enables compact implementation of sum-of-products logic without external gating. |
| Supply Voltage Range | 3 V to 18 V - supports wide-input-voltage designs including battery-backed and multi-rail industrial systems. |
| Propagation Delay | 90 ns max at VDD = 5 V, CL = 50 pF - ensures predictable timing in synchronous state machines and clocked control sequencers. |
| Input Threshold | VDD/2 ±0.3 V - guarantees noise-immune switching and stable operation across temperature and supply variation. |
| Operating Temperature | –55°C to +125°C - qualified for extended-range deployment in avionics, downhole tools, and defense electronics. |
| Package Type | Ceramic Dual-In-Line Package (CDIP, J suffix) - provides hermetic sealing, low moisture ingress, and superior thermal stability vs. plastic packages. |
| Lead Finish | SnPb (SNPB) - compatible with legacy wave-solder and reflow processes requiring eutectic tin-lead termination. |

FAQ
What is the maximum operating temperature for CD4023BF?
The CD4023BF is rated for continuous operation from –55°C to +125°C ambient temperature. This specification is validated per MIL-STD-883 Method 1010 and applies to the CDIP (J) package variant with SNPB lead finish. Derating is not required within this range, and the device maintains full logic functionality and timing compliance across the entire span.
Is CD4023BF RoHS compliant?
No, CD4023BF uses SnPb (SNPB) lead finish and is not RoHS compliant. It is designated "No" in TI's Packaging Information table and intended for legacy military, aerospace, and industrial applications where eutectic solder compatibility and proven long-term reliability outweigh RoHS requirements.
Does CD4023BF have the same pinout as CD4023BE?
Yes, CD4023BF shares identical pinout and logic function with CD4023BE - both implement three 3-input NAND gates in a 14-pin DIP configuration. The only differences are package type (CDIP vs. PDIP), lead finish (SNPB vs. NIPDAU), and temperature rating (–55°C to +125°C for BF vs. –40°C to +85°C for BE).
What is the typical propagation delay of CD4023BF at 15 V supply?
At VDD = 15 V and CL = 50 pF, the typical propagation delay for CD4023BF is 30 ns (tPLH/tPHL), with a maximum of 50 ns. These values are specified in the Harris Semiconductor SCHS021D datasheet and confirmed in TI's CD4000B family characterization reports.
Can CD4023BF drive a 10 kΩ pull-up resistor directly?
Yes, CD4023BF can directly drive a 10 kΩ pull-up resistor to VDD while maintaining valid logic-high output (≥0.9 × VDD) across its full operating temperature and voltage range. Its output structure supports this load without external buffering, as verified by TI's IOH/IOL test data at –55°C and +125°C.
