Product details
Overview
CD74HC107MT 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, supports -55°C to +125°C industrial/military temperature range, and drives 10 LSTTL loads - used in synchronous logic control, state machines, and clock-domain synchronization circuits.
For engineers reviewing the CD74HC107MT datasheet, CD74HC107MT pinout, CD74HC107MT application, or CD74HC107MT equivalent, this page provides verified functional identity, SOIC-14 package mapping, timing parameters (tPLH/tPHL, tSU, fMAX), noise immunity specs (30% VCC hysteresis), and validated alternatives for logic design reuse and obsolescence mitigation.
Technical Context
This device implements two independent edge-triggered J-K flip-flops sharing no internal coupling - each with dedicated J, K, clock (CP), and asynchronous reset (R) inputs plus true and complemented outputs (Q, Q̅). State change occurs only on the high-to-low transition of CP; reset overrides clocking and forces Q = L regardless of J/K state.
It belongs to the HC CMOS logic family: rail-to-rail input thresholds (VIH = 1.5V min @ 2V, 3.15V @ 4.5V), low quiescent current (ICC ≤ 80µA over full temp range), and balanced propagation delays (tPLH = tPHL = 14ns typ @ 5V/15pF). Hysteresis on CP inputs improves noise rejection without external Schmitt triggers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | HC CMOS - compatible with 2V–6V supply; not TTL-input-compatible (use HCT variant for LSTTL input levels) |
| Max Clock Frequency | 60 MHz @ VCC = 5V, CL = 15pF - enables high-speed counter/state machine operation in digital control systems |
| Propagation Delay | 14 ns typical (CP to Q, 5V/15pF) - ensures tight timing margins in synchronous designs with <25 ns cycle budgets |
| Input Hysteresis | 30% of VCC - suppresses false triggering from slow-rising/noisy clock signals without external filtering |
| Operating Temperature | -55°C to +125°C - qualified for aerospace, defense, and under-hood automotive applications per MIL-PRF-38535 |
| Output Drive | 10 LSTTL loads - sufficient to fan out directly to multiple downstream logic gates without buffers |
| Supply Voltage Range | 2V to 6V - supports mixed-voltage system interfacing (e.g., 3.3V logic controlling 5V peripherals) |
Pinout & Package
CD74HC107MT is housed in a 14-lead small-outline integrated circuit (SOIC) package, 3.9mm wide, 1.75mm max height, with standard JEDEC MS-012AB footprint and RoHS-compliant NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1J | First flip-flop's J (set) data input - high enables toggle/set on next negative clock edge |
| 2 | 1Q | First flip-flop's true output - reflects stored state; complements 1Q̅ (pin 3) |
| 3 | 1Q̅ | First flip-flop's inverted output - provides complementary signal for differential routing or enable logic |
| 4 | 1K | First flip-flop's K (reset) data input - high enables toggle/reset on next negative clock edge |
| 5 | 2Q | Second flip-flop's true output - electrically isolated from first section; usable as independent register |
| 6 | 2Q̅ | Second flip-flop's inverted output - matches 2Q phase relationship; supports dual-channel feedback paths |
| 7 | GND | Ground reference - must be low-impedance connection; shared return for both flip-flops and I/O |
| 8 | 2J | Second flip-flop's J input - functionally identical to pin 1 but isolated timing domain |
| 9 | 2K | Second flip-flop's K input - independent control of second stage; no crosstalk with first flip-flop |
| 10 | 2CP | Second flip-flop's clock input - negative-edge sensitive; may be driven separately from 1CP (pin 13) |
| 11 | 2R | Second flip-flop's asynchronous reset - active-low; forces 2Q = L immediately, overriding clock and J/K |
| 12 | 1CP | First flip-flop's clock input - negative-edge triggered; hysteresis improves noise margin on slow edges |
| 13 | 1R | First flip-flop's asynchronous reset - independent of second section; enables selective reset in multi-stage logic |
| 14 | VCC | Positive supply - 2V–6V range; decoupling capacitor (0.1 µF ceramic) required within 1 cm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Reset per Flip-Flop | Independent active-low R pins (1R, 2R) allow selective clearing without affecting other stage or requiring clock alignment |
| Negative-Edge Clock Triggering | State changes occur only on high-to-low CP transitions - eliminates race conditions in cascaded counters |
| Hysteresis on Clock Inputs | 30% VCC input threshold hysteresis rejects noise spikes and accommodates slow-rise clocks up to 1000 ns (2V) |
| Complementary Outputs | Dedicated Q and Q̅ pins per flip-flop eliminate need for external inverters in toggle or enable logic |
| Wide Supply Range (2V–6V) | Supports direct interface between 3.3V microcontrollers and 5V legacy peripherals without level shifters |
| High Noise Immunity | NIH/NIL = 30% VCC ensures reliable operation in electrically noisy environments (e.g., motor drive control boards) |

FAQ
What is the operating voltage range for CD74HC107MT?
The CD74HC107MT operates from 2V to 6V DC supply voltage. At 2V, it guarantees VIH ≥ 1.5V and VIL ≤ 0.5V; at 5V, VIH ≥ 3.15V and VIL ≤ 1.35V. This wide range allows interoperability between 3.3V and 5V logic domains without level-shifting circuitry - a key advantage over TTL or HCT variants that require tighter 4.5V–5.5V rails.
Does CD74HC107MT support asynchronous reset functionality?
Yes, CD74HC107MT features two independent asynchronous reset inputs: 1R (pin 13) for the first J-K flip-flop and 2R (pin 11) for the second. Both are active-low and override clock and J/K inputs immediately - forcing Q = L regardless of clock edge or data state. This enables deterministic initialization and fault recovery in safety-critical logic designs.
What is the maximum clock frequency supported by CD74HC107MT?
CD74HC107MT achieves a maximum clock frequency (fMAX) of 60 MHz when operated at VCC = 5V with a 15pF load capacitance and ambient temperature of 25°C. At full industrial range (-55°C to +125°C), fMAX degrades to 4 MHz (2V), 20 MHz (4.5V), and 23 MHz (6V) - values confirmed in TI's SCHS139D datasheet switching specifications table.
Is CD74HC107MT pin-compatible with CD74HCT107E?
No - CD74HC107MT and CD74HCT107E share identical pin assignments (SOIC-14 vs PDIP-14), but differ in input threshold compatibility: CD74HC107MT accepts 2V–6V supplies with CMOS-level inputs, while CD74HCT107E requires 4.5V–5.5V and accepts LSTTL input voltages (VIH ≥ 2V, VIL ≤ 0.8V). They are functionally identical but not electrically interchangeable without supply and interface redesign.
What package type does CD74HC107MT use, and what are its key mechanical dimensions?
CD74HC107MT uses a 14-lead SOIC (Small Outline Integrated Circuit) package per JEDEC MS-012AB, designated "D" in TI's packaging nomenclature. Its dimensions are 8.75 mm × 3.91 mm × 1.75 mm max height, with 1.27 mm lead pitch and NiPdAu lead finish. The package is RoHS-compliant and rated for moisture sensitivity level 1 (unlimited floor life at ≤30°C/60% RH).
