Product details
Overview
CD4085BM96 from Texas Instruments is a dual 2-input AND-OR-Invert (AOI) gate logic IC in 14-pin SOIC package, operating over 3V–18V supply range with typical propagation delay of 80 ns at 5V and 100 ns at 10V, used in combinational logic design for signal routing and control decoding in industrial timing circuits.
For engineers reviewing the CD4085BM96 datasheet, CD4085BM96 pinout, CD4085BM96 application, or CD4085BM96 equivalent, key selection factors include its dual AOI function, wide VDD range, CMOS input compatibility, and SOIC-14 packaging with RoHS-compliant green finish and MSL Level-1 rating.
Technical Context
The CD4085BM96 implements two independent 2-input AND-OR-Invert gates, each performing (A·B)+(C·D) then inverting the result - enabling compact implementation of sum-of-products logic without external inverters. Its CMOS architecture ensures high noise immunity and near-zero static current draw.
Designed for legacy-compatible 4000-series logic families, it supports direct interfacing with TTL outputs at VDD ≥ 10V and maintains rail-to-rail output swing across the full 3V–18V supply range, with input thresholds referenced to VDD/2 for consistent switching behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |

IC Role / Device Role / Timing Role: Converts active-high FPGA done/status bits into active-low enable signals for peripheral drivers. Use Value: Avoids need for external inverters, preserving FPGA I/O pins and reducing board area in space-constrained modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar AOI gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4085BE | PDIP-14 package, no moisture sensitivity rating, leaded finish | Suitable for prototyping or through-hole assembly; not recommended for automated SMT production | Select CD4085BE only for hand-soldered evaluation or repair of legacy through-hole boards |
| CD4085BPWR | TSSOP-14 package, 4.4 mm width, 0.65 mm pitch, MSL Level-1 | Better suited for high-density PCB layouts where SOIC footprint is too large | Choose CD4085BPWR when board space is constrained and fine-pitch reflow capability is available |
Compared with CD4085BE and CD4085BPWR, the CD4085BM96 offers optimal balance of automated manufacturability (SOIC-14), RoHS/green compliance, and tape-and-reel delivery (2500 units), making it the preferred choice for volume industrial PCB assembly without layout revision.

FAQ
What logic function does the CD4085BM96 implement?
The CD4085BM96 implements two independent 2-input AND-OR-Invert (AOI) gates, each computing the Boolean expression (A·B)+(C·D) then inverting the result to produce Y̅. This structure enables efficient realization of sum-of-products logic without external inverters, and is confirmed in the Harris Semiconductor SCHS060C datasheet. Each gate operates identically within the CD4085BM96 device.
What is the recommended supply voltage range for CD4085BM96?
The CD4085BM96 is specified to operate across 3V to 18V DC, with guaranteed performance over this full range per the official Texas Instruments datasheet. At 5V, it delivers typical propagation delay of 80 ns; at 10V, delay is 100 ns. Operation below 3V or above 18V may cause unreliable switching or damage the CD4085BM96.
Does CD4085BM96 have any unused pins, and how should they be handled?
Yes, pins 13 and 14 of the CD4085BM96 are marked NC (no internal connection) in the official package drawing D and must remain unconnected. Neither pin should be tied to VDD, GND, or any signal line, as doing so could introduce parasitic coupling or violate the CD4085BM96's internal isolation design.
Is CD4085BM96 RoHS compliant and what is its moisture sensitivity level?
Yes, CD4085BM96 carries a Green (RoHS & no Sb/Br) eco-plan designation with CU NIPDAU lead finish and is rated MSL Level-1 (260°C, unlimited floor life). This confirms full RoHS compliance and eliminates baking requirements prior to reflow - a verified specification documented in TI's Packaging Information Addendum for CD4085BM96.
How does CD4085BM96 compare to standard 74-series logic in terms of voltage compatibility?
Unlike bipolar 74-series logic (e.g., 74LS51), the CD4085BM96 operates from 3V to 18V and interfaces directly with TTL outputs only when VDD ≥ 10V. Its CMOS inputs have VDD/2 thresholds, providing superior noise immunity and eliminating the need for level shifters in mixed-voltage systems where the CD4085BM96 is deployed.
