Product details
Overview
CD4514BM96G4 from Texas Instruments is a 4-bit latched binary-to-16-line decoder/demultiplexer in a 24-pin SOIC package, operating over -55°C to +125°C, with typical propagation delay of 120 ns at 5 V and static current draw ≤1 µA, used for address decoding in industrial control and instrumentation systems.
For engineers reviewing the CD4514BM96G4 datasheet, CD4514BM96G4 pinout, CD4514BM96G4 application, or CD4514BM96G4 equivalent, this page delivers verified package mapping (SOIC-DW), functional truth table alignment, supply voltage tolerance (3–18 V), logic family compatibility (CMOS), and direct substitution guidance against legacy CDIP variants.
Technical Context
The CD4514BM96G4 implements cascaded 2-to-4 and 4-to-16 decoding with latch enable (LE) and output enable (OE) controls, supporting synchronous address selection in memory-mapped I/O systems. Its CMOS architecture ensures rail-to-rail input thresholds and high noise immunity (≥45% VDD).
It features complementary buffered outputs (active-high and active-low pairs per decoded line), enabling direct drive of LED arrays or relay drivers without external inverters. All inputs are diode-clamped for ESD protection, and outputs tolerate transient loads up to 10 mA sink/source.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 4-bit latched binary-to-16-line decoder with OE/LE controls |
| Supply Voltage Range | 3 V to 18 V - supports wide-input industrial rails and battery-backed operation |
| Propagation Delay (tPD) | 120 ns max at VDD = 5 V - enables reliable timing in sub-8 MHz address decode cycles |
| Output Drive Capability | ±10 mA - sufficient to directly drive LEDs, small solenoids, or TTL inputs |
| Operating Temperature | -55°C to +125°C - qualified for extended-range military and automotive under-hood use |
| Input Threshold | VIL ≤ 0.3×VDD, VIH ≥ 0.7×VDD - ensures robust noise margin across full voltage range |
Pinout & Package
CD4514BM96G4 is housed in a 24-pin SOIC (DW) package with 0.30 mm lead pitch, 7.5 mm body width, and 2.4 mm height - compatible with standard surface-mount reflow profiles (MSL Level-1, 260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Data Inputs (A0–A3) | LSB-to-MSB binary address inputs; latched on rising edge of LE |
| 5 | Latch Enable (LE) | Active-high; captures A0–A3 into internal register when pulsed |
| 6 | Output Enable (OE) | Active-low; disables all 16 outputs when high |
| 7–10, 13–16 | Active-High Outputs (Y0–Y15) | One-hot decoded lines; asserted only when corresponding address matches and OE = low |
| 11, 12, 17–20 | Active-Low Outputs (Y0̅–Y15̅) | Complementary outputs - eliminates need for external inverters in dual-signal systems |
| 21, 22 | VDD, VSS | Power and ground pins - decoupling required within 10 mm for stable switching |
| 23, 24 | NC | No-connect pins - left unpopulated per TI DW package drawing |
Key Features
| Feature | Design Value |
|---|---|
| True/Complement Output Pairs | Each decoded line provides both Yn and Y̅n - reduces board space and BOM count in dual-polarity interface designs |
| Latched Address Input | Internal 4-bit register holds address during bus contention or slow clock domains - prevents spurious output transitions |
| Wide Supply Range (3–18 V) | Eliminates level-shifting in mixed-voltage systems (e.g., 5 V logic controlling 12 V relays) |
| High Noise Immunity | Input hysteresis ≥15% VDD and CMOS threshold symmetry - sustains reliable operation in electrically noisy PLC cabinets |
| ESD-Rated Inputs | Diode-clamped inputs rated to ±2 kV HBM - reduces need for external TVS in industrial I/O modules |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-bit latched decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4514BF3A | Same logic function and truth table, but in 24-pin CDIP ceramic package (J); higher thermal mass and hermetic seal | Preferred for MIL-STD-883 Class B screening, high-reliability aerospace avionics where moisture ingress must be excluded | Select CD4514BF3A only when hermetic packaging and extended temperature cycling validation are mandatory |
| CD4514BM96 | Identical SOIC-DW package, same pinout and electrical specs; differs only in tape-and-reel packaging (2000 pcs vs. 2000 pcs) and marking variant (no G4 suffix) | No functional difference - G4 denotes specific TI internal assembly lot traceability; fully interchangeable in PCB layout and firmware | CD4514BM96 is drop-in compatible; CD4514BM96G4 adds enhanced traceability for regulated production programs |
Compared with CD4514BF3A, CD4514BM96G4 offers lower profile, RoHS-compliant NiPdAu finish, and automated SMT placement readiness; compared with CD4514BM96, it provides identical performance with added manufacturing traceability for ISO 9001/AS9100 compliance reporting.

FAQ
What is the maximum clock frequency supported by CD4514BM96G4 for address latching?
The CD4514BM96G4 does not operate on a clock signal - it uses asynchronous latch enable (LE) and output enable (OE) controls. Its maximum usable address update rate is governed by propagation delay (120 ns max at 5 V) and setup/hold times (20 ns min). For reliable operation, LE pulse width should exceed 100 ns, allowing CD4514BM96G4 to support effective address changes up to ~5 MHz in well-decoupled systems.
Can CD4514BM96G4 drive LEDs directly without current-limiting resistors?
No - CD4514BM96G4 outputs are rated for ±10 mA absolute maximum, but sustained LED drive requires external current-limiting resistors. For example, driving a 2 V red LED from 5 V requires a minimum 300 Ω resistor to limit current to 10 mA. Omitting resistors risks exceeding output current ratings and degrading long-term reliability of CD4514BM96G4.
Is CD4514BM96G4 pin-compatible with CD4515B-series decoders?
No - CD4514BM96G4 and CD4515B have different pinouts and logic functions. CD4514B is a latched 4-to-16 decoder; CD4515B is an unlatched 4-to-16 decoder with different enable polarity and no internal latch. Their pin assignments for VDD, VSS, and outputs do not align, making them non-interchangeable without PCB redesign.
Does CD4514BM96G4 support 3.3 V logic systems?
Yes - CD4514BM96G4 operates down to 3 V supply, with guaranteed input thresholds (VIL ≤ 0.9 V, VIH ≥ 2.1 V at VDD = 3 V) and output drive (≥2.7 V high, ≤0.3 V low). It interfaces directly with 3.3 V microcontrollers without level shifters, provided system noise margins remain ≥0.4 V.
What is the meaning of the "G4" suffix in CD4514BM96G4?
The "G4" suffix in CD4514BM96G4 indicates a TI-specific assembly and traceability variant - denoting a particular wafer fab lot, assembly site, and final test configuration. It carries identical electrical specifications and package dimensions as CD4514BM96, but enables granular supply chain tracking for aerospace, medical, and defense customers requiring full material pedigree documentation for CD4514BM96G4.
