Product details
Overview
CD4027BPWRG4 from Texas Instruments is a dual J-K flip-flop IC in TSSOP-16 package, operating across 3–18 V supply, with 16 MHz typical toggle frequency at 10 V, static state retention, and independent set/reset inputs synchronized to positive clock edges. It serves as a synchronous control element in digital logic sequencing, counter design, and register staging.
For engineers reviewing the CD4027BPWRG4 datasheet, CD4027BPWRG4 pinout, CD4027BPWRG4 application, or CD4027BPWRG4 equivalent, this page delivers verified functional roles, validated timing parameters, confirmed package dimensions, real-world use-value per application, and two rigorously cross-checked alternative parts for industrial logic design.
Technical Context
The CD4027BPWRG4 implements two independent CMOS J-K flip-flops with edge-triggered clocking on the rising edge, asynchronous active-high Set and Reset inputs, and complementary Q/Q̅ outputs per channel. Each flip-flop supports toggle, latch, and memory retention modes via J/K input combinations.
It operates over –55°C to +125°C, meets JEDEC Standard No. 138 for 'B' series CMOS, and features symmetrical output drive (±6.8 mA at 15 V), 1 μA max input current at 18 V, and noise margins of 1 V (5 V), 2 V (10 V), and 2.5 V (15 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 18 V - Enables direct interface with legacy 5 V, modern 12 V, and wide-range industrial rails without level-shifting. |
| Max Clock Toggle Frequency | 16 MHz at VDD = 10 V - Supports medium-speed synchronous logic in counters and state machines up to ~62 ns minimum clock period. |
| Propagation Delay (tPLH/tPHL) | 45–90 ns at VDD = 15 V - Ensures predictable setup/hold timing margins for cascaded logic with 50 pF load. |
| Output Drive Strength | ±6.8 mA at VDD = 15 V - Sufficient to directly drive multiple 74HC inputs or small LED indicators without external buffers. |
| Input Leakage Current | 1 μA max at 18 V over full temp range - Guarantees reliable static state hold in battery-backed or low-power monitoring circuits. |
| Operating Temperature | –55°C to +125°C - Qualified for under-hood automotive, industrial PLC, and aerospace subsystem environments. |
Pinout & Package
TSSOP-16 package (PW suffix), 5.0 mm × 4.4 mm × 1.2 mm body height, 0.65 mm lead pitch, RoHS-compliant NIPDAU finish, MSL Level-1 (260°C reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Q2, Q̅2 | Complementary outputs for channel 2 - Enable direct connection to downstream logic or differential sensing without inversion logic. |
| 3 | CLOCK2 | Rising-edge clock input for channel 2 - Synchronizes state change only on positive transition; immune to glitches during low/high hold. |
| 4 | RESET2 | Asynchronous active-high reset for channel 2 - Forces Q2 = 0, Q̅2 = 1 regardless of clock or J/K state; overrides all logic functions. |
| 5, 6 | K2, J2 | Control inputs for channel 2 - J = 1/K = 1 enables toggle mode; J = 1/K = 0 sets Q = 1; J = 0/K = 1 resets Q = 0. |
| 7 | SET2 | Asynchronous active-high set for channel 2 - Forces Q2 = 1, Q̅2 = 0 independently of clock or J/K - used for initialization or fault recovery. |
| 8 | VSS | Ground reference - Must be connected to system common; decoupling capacitor (0.1 µF) recommended within 5 mm. |
| 9, 10 | SET1, J1 | Asynchronous set and data input for channel 1 - Enables independent control of first flip-flop without affecting second channel. |
| 11, 12 | K1, RESET1 | Data complement and asynchronous reset for channel 1 - Allows full J-K functionality plus fail-safe reset capability per channel. |
| 13 | CLOCK1 | Rising-edge clock for channel 1 - Electrically isolated from CLOCK2; supports dual-clock domain operation when needed. |
| 14, 15 | Q̅1, Q1 | Complementary outputs for channel 1 - Matched rise/fall times ensure clean signal integrity for clock distribution or feedback paths. |
| 16 | VDD | Positive supply rail - Requires local 0.1 µF ceramic bypass capacitor between VDD and VSS near pin 16 to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Static flip-flop operation | Retains state indefinitely with clock high or low - eliminates need for continuous clocking in standby or power-gated modes. |
| Symmetrical output characteristics | Matched tPLH/tPHL and IOH/IOL drive - ensures balanced timing in feedback loops and prevents duty-cycle distortion in oscillators. |
| 100% quiescent current tested at 20 V | Validated IDD ≤ 20 μA at VDD = 20 V - confirms robust oxide integrity and long-term reliability in overvoltage-tolerant designs. |
| Noise margin scalability | 1 V (5 V), 2 V (10 V), 2.5 V (15 V) - provides predictable noise immunity across supply voltages without redesign. |
| JEDEC B-series compliance | Fully conforms to JESD138 - guarantees interoperability with other 'B' series CMOS logic (e.g., CD4013B, CD4017B) in mixed-family systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual J-K flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4027BM96 | SOIC-16 package, same electrical specs, MSL Level-1, 2500/reel tape-and-reel - larger footprint (10.4 × 5.4 mm vs. 5.0 × 4.4 mm), 2.0 mm max height. | Better thermal mass for high-temperature soldering; less suitable for ultra-dense PCBs where TSSOP's compactness is critical. | Select CD4027BM96 if board assembly uses SOIC-compatible pick-and-place or requires higher thermal dissipation in continuous 125°C operation. |
| SN74HC109PWR | CMOS HC-family, 2–6 V supply only, 60 MHz max toggle, 3.3 V logic compatible, lower propagation delay (20 ns typ), but no 12/15 V support. | Optimized for 3.3 V embedded systems; lacks wide-voltage flexibility and extended temperature rating (–40°C to +85°C only). | Select SN74HC109PWR only for new 3.3 V designs requiring higher speed and lower power; not suitable for legacy 5/12/15 V mixed-rail systems. |
Compared with CD4027BPWRG4, CD4027BM96 offers identical logic function in a larger, thermally robust SOIC package, while SN74HC109PWR trades wide supply range and military-grade temperature tolerance for higher speed and 3.3 V compatibility - making CD4027BPWRG4 the sole choice for multi-voltage industrial control upgrades.

FAQ
What is the maximum clock frequency supported by CD4027BPWRG4?
The CD4027BPWRG4 supports a maximum clock toggle frequency of 16 MHz at VDD = 10 V (typical), 12 MHz at VDD = 15 V, and 3.5 MHz at VDD = 5 V per datasheet Section 6.4. These values assume CL = 50 pF and input rise/fall times ≤ 20 ns. Derating applies above 85°C ambient.
Does CD4027BPWRG4 support asynchronous set and reset functions?
Yes, CD4027BPWRG4 provides fully asynchronous active-high Set and Reset inputs for each of its two J-K flip-flops (pins 7/9/4/12). These override clock and J/K states immediately, forcing Q = 1 or Q = 0 respectively - enabling deterministic initialization and fault recovery independent of clock timing.
Is CD4027BPWRG4 pin-compatible with CD4013B dual D-type flip-flop?
No, CD4027BPWRG4 is not pin-compatible with CD4013B. While both are 16-pin TSSOP logic ICs with shared VDD/VSS and Q/Q̅ output locations, CD4027BPWRG4 allocates pins for J, K, Set, Reset, and dual clocks - whereas CD4013B uses those positions for D inputs, preset/clear, and single clock. Board-level replacement requires schematic and layout revision.
What is the operating temperature range of CD4027BPWRG4?
The CD4027BPWRG4 is rated for operation from –55°C to +125°C, as specified in Section 6.1 Absolute Maximum Ratings and confirmed in the Packaging Information table. This full military-grade temperature range is validated across all electrical parameters in the datasheet's Recommended Operating Conditions and Static/Dynamic Electrical Characteristics tables.
Can CD4027BPWRG4 operate reliably at 3.3 V supply?
Yes, CD4027BPWRG4 is specified down to 3 V supply (Section 6.2 Recommended Operating Conditions), with guaranteed functionality including 3.5 MHz toggle frequency, valid noise margins, and full input/output logic thresholds. However, propagation delay increases and output drive weakens versus 5 V or higher - verify timing margins in 3.3 V designs using worst-case values from Table 6.4.
