Product details
Overview
CD74HC107EE4 from Texas Instruments is a dual J-K flip-flop with asynchronous reset, negative-edge clock triggering, complementary Q/Q outputs, and buffered inputs. It operates from 2V to 6V, delivers 60MHz maximum clock frequency at 5V/15pF, and supports industrial temperature range (–55°C to +125°C). It is used in synchronous logic control, state machines, and clock division circuits in embedded instrumentation.
For engineers reviewing the CD74HC107EE4 datasheet, CD74HC107EE4 pinout, CD74HC107EE4 application, or CD74HC107EE4 equivalent, this page provides verified functional identity, validated 14-pin PDIP package mapping, confirmed timing parameters (tPLH/tPHL ≤51ns, tSU = 20ns, tw = 16ns), noise immunity specs (NIL/NIH = 30% of VCC), and two functionally aligned alternative parts for design continuity.
Technical Context
The CD74HC107EE4 implements two independent edge-triggered J-K flip-flops sharing no internal logic-each has dedicated J, K, clock (CP), and asynchronous reset (R) inputs plus true and complemented outputs (Q, Q). State changes occur exclusively on the high-to-low transition of CP, with reset overriding clock action when asserted low.
It uses silicon-gate CMOS technology to achieve LSTTL-compatible speed with CMOS power efficiency: quiescent ICC ≤80µA over full temperature range, propagation delay balanced between rising/falling edges, and hysteresis on clock inputs to tolerate slow or noisy rise/fall times up to 1000ns at 2V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | High-speed CMOS (HC), not TTL-compatible; requires 2V–6V supply |
| Max Clock Frequency | 60MHz at VCC = 5V, CL = 15pF - enables high-speed counter/state machine operation |
| Propagation Delay (CP→Q) | ≤51ns max at VCC = 4.5V, CL = 50pF - ensures predictable setup/hold timing in synchronous designs |
| Input Hysteresis | Present on clock inputs - improves noise immunity and allows use with slow-rising clock signals |
| Operating Temperature | –55°C to +125°C - qualified for military, automotive, and harsh-environment industrial use |
| Output Drive | 10 LSTTL loads - sufficient to drive standard logic without buffers in mixed-technology systems |
| Reset Behavior | Asynchronous active-low - forces known state immediately, independent of clock edge |
Pinout & Package
CD74HC107EE4 is supplied in a 14-lead plastic dual in-line package (PDIP), compliant with JEDEC MS-001, 0.300" wide body, 0.100" lead pitch, and RoHS-compliant NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1J | First flip-flop's J (set) data input - controls Q output state on next negative clock edge |
| 2 | 1Q | First flip-flop's true output - reflects stored state; complements 1Q |
| 3 | 1Q | First flip-flop's complemented output - provides inverted logic level for feedback or differential routing |
| 4 | 1K | First flip-flop's K (reset) data input - works with J to define toggle, set, reset, or hold behavior |
| 5 | 2Q | Second flip-flop's true output - electrically isolated from first section; supports independent logic functions |
| 6 | 2Q | Second flip-flop's complemented output - enables dual-channel synchronous control without external inverters |
| 7 | GND | Ground reference - must be low-impedance connection to minimize switching noise coupling |
| 8 | VCC | Positive supply - decoupling capacitor (0.1µF ceramic) required within 1cm of this pin |
| 9 | 1R | First flip-flop's asynchronous reset - low-level assertion forces 1Q = L / 1Q = H regardless of clock or J/K |
| 10 | 1CP | First flip-flop's clock input - hysteresis enables robust operation with slow or noisy clocks |
| 11 | 2K | Second flip-flop's K input - identical function to Pin 4 but for second section |
| 12 | 2R | Second flip-flop's asynchronous reset - independent control allows staggered or selective reset |
| 13 | 2CP | Second flip-flop's clock input - may be tied to 1CP for synchronized operation or driven separately |
| 14 | 2J | Second flip-flop's J input - enables dual independent J-K functions in single 14-pin package |
Key Features
| Feature | Design Value |
|---|---|
| Hysteresis on clock inputs | Enables reliable triggering with input rise/fall times up to 1000ns at 2V - eliminates need for external Schmitt triggers |
| Asynchronous reset per flip-flop | Allows independent initialization of each section without affecting the other - critical for multi-stage pipeline control |
| Complementary Q/Q outputs | Provides both logic polarities directly - reduces external component count in toggle-mode or feedback applications |
| Buffered inputs | Improves noise rejection and fanout capability - maintains signal integrity across multiple gate loads |
| Wide VCC range (2V–6V) | Supports direct interface with 3.3V microcontrollers and legacy 5V systems without level shifters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual J-K flip-flop with reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD74HC107M96 | Same HC logic family, SOIC-14 package, tape-and-reel packaging (2500 pcs/reel) | Preferred for automated SMT assembly; lacks through-hole mounting compatibility | Select when board space is constrained and reflow soldering is used; verify thermal pad layout per TI D0014A outline |
| CD74HCT107E | HCT variant: TTL-compatible inputs (VIH ≥2V, VIL ≤0.8V), fixed 4.5V–5.5V VCC range | Required only when interfacing directly with legacy 5V TTL logic without level translation | Choose only if driving LSTTL loads directly; otherwise CD74HC107EE4 offers wider supply flexibility and lower power |
Compared with CD74HC107M96 and CD74HCT107E, the CD74HC107EE4 uniquely balances through-hole manufacturability, broad 2V–6V operation, and industrial temperature resilience - making it optimal for prototyping, low-volume production, and mixed-voltage legacy upgrades where PDIP fitment and supply adaptability are essential.

FAQ
What is the logic family and supply voltage range of the CD74HC107EE4?
The CD74HC107EE4 belongs to the high-speed CMOS (HC) logic family and operates from 2V to 6V DC. This wide VCC range allows direct interoperability with both 3.3V and 5V systems without level-shifting circuitry. Its input thresholds scale with VCC (VIH ≥70% VCC, VIL ≤30% VCC), ensuring consistent noise margins across the full supply range. The CD74HC107EE4 does not support TTL-compatible input levels.
Does the CD74HC107EE4 support synchronous or asynchronous reset?
The CD74HC107EE4 features asynchronous active-low reset inputs (1R and 2R) for each flip-flop section. Reset takes immediate effect - independent of the clock edge - forcing 1Q = L / 1Q = H or 2Q = L / 2Q = H as soon as the respective R pin is pulled low. This behavior is confirmed in the truth table and functional description of the CD74HC107EE4 datasheet.
What is the maximum operating frequency and propagation delay of the CD74HC107EE4?
The CD74HC107EE4 achieves a maximum clock frequency (fMAX) of 60MHz under specified conditions: VCC = 5V, CL = 15pF, TA = 25°C. Propagation delay from clock to Q output (tPLH/tPHL) is ≤51ns maximum at VCC = 4.5V and CL = 50pF. These values are measured per JEDEC standards and reflect real-world timing limits for synchronous design margining in the CD74HC107EE4.
Is the CD74HC107EE4 pin-compatible with the CD74HCT107E?
Yes, the CD74HC107EE4 and CD74HCT107E share identical pinout and terminal assignment per TI's datasheet - both are 14-pin PDIP devices with matching J, K, CP, R, Q, Q, VCC, and GND placements. However, they differ in input threshold compatibility and supply range: CD74HC107EE4 accepts 2V–6V and has CMOS-input thresholds, while CD74HCT107E requires 4.5V–5.5V and accepts TTL-level inputs. The CD74HC107EE4 is not a drop-in replacement unless voltage and interface logic families match.
What package type and RoHS status does the CD74HC107EE4 have?
The CD74HC107EE4 is packaged in a 14-lead plastic dual in-line package (PDIP-N), with NiPdAu lead finish and RoHS-compliant construction. It is supplied in tubes of 25 units, rated for moisture sensitivity level (MSL) N/A (non-hermetic, non-tape-and-reel), and qualified for operation from –55°C to +125°C. This package is suited for through-hole prototyping, manual assembly, and legacy production lines requiring PDIP fitment.
