Product details
Overview
CD4027BPW from Texas Instruments is a CMOS dual J-K flip-flop in 16-pin TSSOP package, operating from 3 V to 18 V supply, delivering 16 MHz typical toggle frequency at 10 V, with static operation and independent set/reset functionality per channel. It serves as a synchronous control element in digital logic sequencing, register staging, and clocked state machines.
For engineers reviewing the CD4027BPW datasheet, CD4027BPW pinout, CD4027BPW application, or CD4027BPW equivalent, this page delivers verified pin functions, JEDEC-compliant B-series CMOS timing behavior, noise margin specs across 5/10/15 V rails, and validated alternatives for industrial control and legacy logic upgrades.
Technical Context
The CD4027BPW implements two fully independent edge-triggered J-K flip-flops with asynchronous active-high Set and Reset inputs, where state transitions occur on the positive-going clock edge. Each channel features buffered complementary Q and Q̅ outputs with symmetrical drive capability.
Its static CMOS architecture enables indefinite state retention at any stable clock level (high or low), and its input structure supports direct compatibility with CD4013B D-type flip-flop layouts. Noise margins are specified at 1 V (5 V VDD), 2 V (10 V), and 2.5 V (15 V) over full temperature range.

|---|---|---|
| 1, 2 | Q2, Q2̅ | Dual complementary outputs for channel 2 - enable direct connection to downstream logic or LED indicators without inversion |
| 3 | CLOCK2 | Positive-edge-triggered clock input for channel 2 - synchronizes state changes only on rising transition, rejecting glitches on falling edge |
| 4 | RESET2 | Asynchronous active-high reset for channel 2 - forces Q2 = 0 regardless of clock or J/K state |
| 5, 6 | K2, J2 | Control inputs for channel 2 - define next-state logic (set, reset, toggle, hold) synchronized to CLOCK2 |
| 7 | SET2 | Asynchronous active-high set for channel 2 - forces Q2 = 1 independently of clock or J/K |
| 8 | VSS | Ground reference - must be low-impedance return path for all internal switching currents |
| 9, 10 | SET1, J1 | Asynchronous set and synchronous J input for channel 1 - support mixed-mode control (immediate vs. clocked action) |
| 11, 12 | K1, RESET1 | Synchronous K input and asynchronous reset for channel 1 - allow independent initialization and data steering |
| 13 | CLOCK1 | Positive-edge-triggered clock for channel 1 - electrically isolated from CLOCK2 for dual-clock domain use |
| 14, 15 | Q1̅, Q1 | Complementary outputs for channel 1 - provide both true and inverted logic levels for fanout or differential signaling |
| 16 | VDD | Positive supply rail - decoupling capacitor required within 10 mm to suppress switching noise |

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 die, identical AC/DC specs; MSL Level-1, 260°C reflow rated | Preferred for new PCB designs requiring surface-mount reliability and automated assembly compatibility | Select CD4027BM96 when board space permits larger SOIC footprint and long-term production continuity is prioritized |
| SN74HC109PWR | High-speed CMOS; 3.3 V optimized; 70 MHz fMAX; different pinout; no VDD/VSS symmetry | Used in modern low-voltage systems where 5 V tolerance and legacy voltage range are not required | Choose SN74HC109PWR only if supply is strictly 2–6 V and higher speed justifies redesigning layout and logic interface |
Compared with CD4027BM96, the CD4027BPW offers identical logic function but in a smaller TSSOP footprint ideal for space-constrained upgrades; versus SN74HC109PWR, it trades speed for universal 3–18 V operation and JEDEC B-series interoperability in mixed-voltage legacy systems.

FAQ
What is the maximum clock frequency supported by CD4027BPW at 5 V supply?
The CD4027BPW supports a maximum clock toggle frequency of 3.5 MHz at 5 V supply, as specified in Section 6.4 of the TI datasheet SCHS032D. This value reflects guaranteed performance under recommended operating conditions with CL = 50 pF and input rise/fall times ≤ 20 ns. The CD4027BPW maintains functional correctness up to this rate but does not guarantee timing margins beyond the published 3.5 MHz limit at 5 V.
Does CD4027BPW support asynchronous set and reset on both flip-flop channels?
Yes, CD4027BPW provides dedicated asynchronous SET1, RESET1, SET2, and RESET2 inputs - each active-high and independent of clock or J/K states. When asserted, SETx forces Qx = 1 and RESETx forces Qx = 0 immediately, overriding all synchronous inputs. This behavior is confirmed in the Functional Modes table (Section 8.2) and Pin Functions table (Section 5) of the CD4027BPW datasheet.
Is CD4027BPW pin-compatible with CD4013B dual D-type flip-flop?
No, CD4027BPW is not pin-compatible with CD4013B. While both are 16-pin dual flip-flops with shared VDD/VSS and complementary outputs, CD4027BPW allocates pins for J, K, SET, RESET, and CLOCK per channel (e.g., pins 10/11/9/12/13 for CH1), whereas CD4013B uses pins for D, SET, RESET, and CLOCK (e.g., pins 5/6/4/3/2 for CH1). The CD4027BPW datasheet explicitly states "compatibile operation" - meaning functional interoperability in system design, not mechanical or electrical pin mapping.
What is the input leakage current specification for CD4027BPW at 18 V and 25°C?
The CD4027BPW exhibits a maximum input current of 100 nA at 18 V and 25°C, as documented in Section 1 (Features) and Table 6.3 (Static Electrical Characteristics) of the TI datasheet. This ultra-low leakage enables high-impedance node interfacing and reduces loading on sensitive analog or sensor front-ends without external buffering.
Can CD4027BPW operate reliably at –55°C ambient temperature?
Yes, CD4027BPW is fully specified and tested for operation from –55°C to +125°C, as stated in Section 6.1 (Absolute Maximum Ratings) and Section 6.2 (Recommended Operating Conditions). Its B-series CMOS process and hermetic-grade packaging ensure stable propagation delay, noise margin, and output drive across this full military-grade temperature range - confirmed by TI's production screening and qualification testing.
