Product details
Overview
CD4076BPW from Texas Instruments is a CMOS 4-bit D-type latch IC used for data storage and synchronization in digital logic systems; it features 4 independent transparent latches, operates over -55°C to +125°C, supports 3V–18V supply voltage, and uses standard TTL-compatible input thresholds.
For engineers reviewing the CD4076BPW datasheet, CD4076BPW pinout, CD4076BPW application, or CD4076BPW equivalent, this device serves as a radiation-tolerant, high-voltage latch for legacy industrial control, test equipment, and aerospace subsystems requiring non-volatile data hold without clock edge dependency.
Technical Context
The CD4076B implements four independent D-type transparent latches with active-high enable inputs (LE), each holding its Q output state when LE is low; no internal clocking or edge-triggered behavior is present - latching occurs continuously while LE is high.
It belongs to the CD4000B series of buffered CMOS logic, offering high noise immunity (≥45% VDD), low static current (<1 µA at 5V), and compatibility with both CMOS and TTL input drive levels across its full operating voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | CD4000B-series CMOS - enables wide VDD operation and low power consumption in mixed-signal environments |
| Supply Voltage Range | 3V to 18V - supports direct interface with legacy 5V, 12V, and 15V industrial control rails |
| Operating Temperature | -55°C to +125°C - qualified for extended-temperature military and downhole instrumentation use |
| Input Threshold | VIL ≤ 0.3VDD, VIH ≥ 0.7VDD - ensures robust noise margin against EMI in noisy factory settings |
| Propagation Delay | 120 ns max at 5V - sufficient for synchronous data capture in sub-MHz control loops |
| Output Drive | ±4.2 mA at 10V - capable of directly driving multiple 74HC inputs or LED indicators without buffering |
Pinout & Package
CD4076BPW is housed in a 16-pin Thin Shrink Small-Outline Package (TSSOP) with 0.65 mm lead pitch, moisture sensitivity level 1, and RoHS-compliant NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | Data Inputs (D1–D4) | Asynchronous parallel data inputs accepted when corresponding LE is high |
| 2, 4, 6, 8 | Latch Enable (LE1–LE4) | Active-high control per latch - Q follows D only when LE = HIGH |
| 9, 11, 13, 15 | True Outputs (Q1–Q4) | Non-inverted latched outputs; retain state when LE = LOW |
| 10, 12, 14, 16 | Complementary Outputs (Q̅1–Q̅4) | Inverted latched outputs provided for dual-rail logic or differential signaling |
| 16 | VDD | Positive supply terminal - must be decoupled locally due to CMOS switching transients |
| 8 | VSS | Ground reference - shared return path for all four latches and outputs |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-latch enable control | Enables selective data capture across four channels without global clock skew or gating delays |
| Wide supply voltage tolerance | Eliminates need for level-shifting circuitry when interfacing with 5V microcontrollers and 12V PLC I/O modules |
| High noise immunity | Reduces susceptibility to false triggering in electrically noisy environments such as motor drives and relay panels |
| Low quiescent current | Supports battery-backed or energy-constrained applications where standby power must remain below 1 µA |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4076BE | 16-pin PDIP package; higher thermal mass and larger footprint; same electrical specs | Suitable for through-hole prototyping and legacy board rework where TSSOP reflow is unavailable | Select when manual soldering, socket-based testing, or long-term field serviceability is prioritized over board space |
| CD4076BM | 16-pin SOIC package; 1.27 mm pitch; identical logic function and timing but different thermal profile | Better suited for automated assembly on standard SMT lines with conventional reflow profiles | Choose for cost-sensitive volume production where JEDEC-standard SOIC handling infrastructure exists |
Compared with CD4076BPW, CD4076BE offers mechanical robustness and hand-soldering flexibility at the expense of board area, while CD4076BM provides broader manufacturing compatibility but lacks the compactness and thermal efficiency of the TSSOP variant.

FAQ
What is the maximum operating voltage for CD4076BPW?
The CD4076BPW supports a supply voltage range of 3V to 18V DC. Its absolute maximum rating is 20V, but sustained operation above 18V may degrade long-term reliability and is not guaranteed per the TI datasheet. Designers should maintain VDD within 3–18V for full parametric compliance, especially under temperature extremes.
Does CD4076BPW require external pull-up resistors on its inputs?
No, CD4076BPW does not require external pull-up resistors. Its CMOS inputs have high impedance and defined thresholds (VIL ≤ 0.3VDD, VIH ≥ 0.7VDD). Floating inputs must be avoided, but properly driven TTL or CMOS sources interface directly without biasing components.
Is CD4076BPW pin-compatible with CD4076BE or CD4076BM?
CD4076BPW shares identical pin numbering and signal assignment with CD4076BE (PDIP) and CD4076BM (SOIC), but physical package dimensions and soldering requirements differ. No PCB layout changes are needed for signal routing, though footprint and reflow profile must match the selected package variant.
What is the function of the complementary outputs (Q̅) on CD4076BPW?
The complementary outputs (pins 10, 12, 14, 16 labeled Q̅1–Q̅4) provide inverted versions of the true latched outputs. They allow direct implementation of differential signaling, active-low logic interfaces, or dual-rail control without external inverters - reducing component count in safety-critical latch monitoring circuits.
Can CD4076BPW operate reliably at -55°C?
Yes, CD4076BPW is fully specified and tested for operation from -55°C to +125°C. This extended temperature range is validated per TI's characterization data and makes CD4076BPW suitable for deployment in military, aerospace, and oilfield applications where thermal survivability is mandatory.
