Product details
Overview
M74HC109RM13TR from STMicroelectronics is a high-speed CMOS dual J-K flip-flop with asynchronous preset and clear, operating from 2V to 6V supply, delivering 67MHz max clock frequency (typ.) at 6V, ±4mA output drive, and 2µA max quiescent current at 25°C - used in synchronous logic control, state machines, and clock-domain synchronization in industrial PLCs.
For engineers reviewing the M74HC109RM13TR datasheet, M74HC109RM13TR pinout, M74HC109RM13TR application, or M74HC109RM13TR equivalent, key selection criteria include asynchronous set/reset timing margins, propagation delay symmetry (tPLH ≅ tPHL), noise immunity (28% VCC min), and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The device implements two independent edge-triggered J-K flip-flops with active-low asynchronous preset (1PR/2PR) and clear (1CLR/2CLR), each responding to the rising edge of its dedicated clock input (1CK/2CK). Logic state transitions follow standard J-K truth table behavior including toggle, hold, set, and reset modes.
All inputs feature silicon-gate C2MOS protection against ESD and transient overvoltage; outputs exhibit symmetrical sourcing/sinking capability (|IOH| = IOL ≥ 4mA) and balanced propagation delays (tPLH/tPHL ≤ 38ns at VCC = 6V, TA = –55°C to 125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2V to 6V - supports mixed-voltage system interfacing and battery-powered operation down to 2V logic levels |
| Max Clock Frequency | 67MHz (typ. at VCC = 6V) - enables high-throughput sequential logic in data path controllers |
| Output Drive Strength | ±4mA (min) - sufficient to drive multiple 74HC inputs or small capacitive loads without buffering |
| Propagation Delay (CK→Q) | 13ns (min) / 38ns (max) at VCC = 6V - ensures deterministic timing for setup/hold-critical state registers |
| Quiescent Supply Current | 2µA (max at TA = 25°C) - minimizes standby power in always-on control subsystems |
| Noise Immunity | VNIH/VNIL = 28% VCC (min) - rejects common-mode noise on control lines in electrically noisy environments |
| Operating Temperature | –55°C to +125°C - qualified for extended industrial and automotive under-hood applications |
Pinout & Package
TSSOP-16 package: 4.9mm × 6.4mm body, 0.65mm pitch, thin-profile surface-mount construction optimized for automated assembly and thermal performance in compact designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1CLR, 2CLR | Active-low asynchronous reset - forces Q = L, Q̄ = H independent of clock or J/K state |
| 2, 14, 3, 13 | 1J, 2J, 1K, 2K | Synchronous data inputs - define next-state logic per J-K truth table on rising clock edge |
| 4, 12 | 1CK, 2CK | Positive-edge-triggered clock - initiates state evaluation and update only on rising transition |
| 5, 11 | 1PR, 2PR | Active-low asynchronous preset - forces Q = H, Q̄ = L regardless of clock or J/K |
| 6, 10 | 1Q, 2Q | True outputs - provide registered logic state after clock edge or async control assertion |
| 7, 9 | 1Q̄, 2Q̄ | Complement outputs - deliver inverted registered state for differential signaling or feedback paths |
| 8 | GND | Ground reference - return path for all internal logic and I/O currents |
| 16 | VCC | Positive supply - powers internal C2MOS circuitry and establishes logic threshold references |
Key Features
| Feature | Design Value |
|---|---|
| Pin-compatible with 74LS109 | Enables drop-in upgrade from bipolar TTL logic without PCB redesign or netlist changes |
| Symmetrical output impedance | Ensures matched rise/fall times and reduced signal distortion in clocked bus interfaces |
| Balanced propagation delays | tPLH ≅ tPHL minimizes duty-cycle degradation when cascading multiple stages |
| Wide voltage operation (2–6V) | Supports direct interface with 3.3V microcontrollers and 5V legacy peripherals |
| High noise immunity | 28% VCC noise margin prevents spurious triggering in motor-drive or relay-control environments |

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 |
|---|---|---|---|
| SN74HC109PWR | Same logic function, identical AC/DC specs, but in 16-pin TSSOP with different moisture sensitivity level (MSL3 vs MSL1) | Requires requalification for humidity-sensitive reflow processes in high-reliability manufacturing | Select when TI-sourced supply chain alignment is required and MSL3 handling infrastructure exists |
| 74AHC109PW,118 | Higher speed (fMAX = 125MHz typ.), lower propagation delay (10ns max), but higher ICC (40µA max) and narrower VCC range (2–5.5V) | Not suitable for 6V systems or ultra-low-power standby; better for high-frequency test fixtures | Choose where timing margin is critical and 6V operation is not needed |
Compared with SN74HC109PWR and 74AHC109PW,118, the M74HC109RM13TR offers optimal balance of 6V tolerance, 2µA standby current, and MSL1 packaging - making it preferred for long-life industrial controllers requiring wide supply flexibility and zero-power retention.

FAQ
What is the maximum clock frequency supported by M74HC109RM13TR?
The M74HC109RM13TR achieves a typical maximum clock frequency of 67MHz at VCC = 6V and TA = 25°C, with guaranteed minimum of 30MHz across the full –55°C to +125°C operating range per AC electrical characteristics table. This value assumes CL = 50pF load and input rise/fall times ≤400ns at 6V.
Does M74HC109RM13TR support asynchronous preset and clear functions?
Yes - pins 1/15 (1CLR/2CLR) and 5/11 (1PR/2PR) provide active-low asynchronous control, allowing immediate state override independent of clock activity. Both preset and clear dominate over J/K inputs and clock edges, with minimum pulse width requirements of 6ns at VCC = 6V as specified in the AC characteristics table.
What package type is used for M74HC109RM13TR?
M74HC109RM13TR uses a 16-pin TSSOP (Thin Shrink Small Outline Package) with 4.9mm × 6.4mm body dimensions, 0.65mm lead pitch, and MSL1 moisture sensitivity rating. Mechanical data confirms compliance with JEDEC MO-153, enabling compatibility with standard SMT assembly lines and reflow profiles.
How does M74HC109RM13TR handle noise on its control inputs?
The device guarantees high noise immunity with VNIH and VNIL specified at 28% of VCC (minimum) across the full operating voltage range, meaning input thresholds remain tightly bounded relative to supply rail. This design prevents false triggering from EMI or crosstalk in noisy industrial environments without requiring external RC filtering.
