Product details
Overview
CD74ACT174M96 from Texas Instruments is a hex D-type positive-edge-triggered flip-flop with asynchronous clear, designed for 4.5V–5.5V operation. It contains six independent flip-flops with single-rail outputs, ±24mA output drive, TTL-compatible inputs, and balanced propagation delays. It is used in synchronous digital logic systems requiring reliable data latching and register storage.
For engineers reviewing the CD74ACT174M96 datasheet, CD74ACT174M96 pinout, CD74ACT174M96 application, or CD74ACT174M96 equivalent, this page delivers verified functional identity, SOIC-16 package mapping, timing parameters (tPLH/tPHL ≤12.6 ns), absolute maximum ratings, and two validated alternative parts for buffer/register use cases.
Technical Context
The CD74ACT174M96 implements six independent D-type latches triggered on the rising edge of CLK, each with dedicated D input and Q output. Its asynchronous CLR input forces all Q outputs low regardless of clock state, enabling global reset functionality.
It uses SCR-latchup-resistant CMOS process technology, supports TTL-level input thresholds (VIL = 0.8 V, VVIH = 2.0 V), and delivers rail-to-rail output swing under ±24 mA load. Propagation delay is balanced across all six channels, and fanout capability reaches 15 F-family devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures compatibility with standard 5-V TTL/CMOS logic rails and stable operation across industrial temperature range. |
| Max Clock Frequency | 91 MHz at –40°C to +85°C - Supports high-speed synchronous register applications without setup/hold violation. |
| tPLH/tPHL | ≤12.6 ns (CL = 50 pF) - Enables precise timing control in pipeline stages and shift registers with minimal skew. |
| IOH/IOL | ±24 mA - Drives heavy capacitive loads or multiple downstream gates without external buffers. |
| Input Compatibility | TTL-voltage compatible - Accepts standard 0.8 V / 2.0 V logic thresholds, eliminating level-shifting in mixed-logic systems. |
| Quiescent Current | 80 μA max at 85°C - Low static power enables use in power-sensitive digital subsystems without thermal derating. |
| ESD Rating | ±2000 V HBM - Robust handling during board assembly and field service without special ESD precautions beyond standard protocols. |
Pinout & Package
CD74ACT174M96 is packaged in a 16-pin SOIC (D) package with 9.9 mm × 6.0 mm body size, gull-wing leads, and RoHS-compliant NiPdAu lead finish. The package is rated MSL Level-1 with unlimited floor life at ≤30°C/60% RH.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLR (Pin 1) | Asynchronous clear input | Active-low global reset: forces all six Q outputs low immediately, independent of clock edge. |
| 1Q–6Q (Pins 2,5,7,10,12,15) | Output terminals | Single-rail complementary outputs - each reflects stored D-input state after positive CLK edge. |
| 1D–6D (Pins 3,4,6,11,13,14) | Data inputs | Independent D inputs per flip-flop - sampled on CLK rising edge and held until next trigger or CLR assertion. |
| CLK (Pin 9) | Clock input | Positive-edge-triggered master clock - synchronizes all six flip-flops simultaneously with <6.2 ns minimum pulse width. |
| VCC (Pin 16) | Power supply | +4.5 V to +5.5 V supply rail - powers internal logic and output drivers; requires local 0.1 µF bypass capacitor. |
| GND (Pin 8) | Ground reference | Common return path for all I/O and internal circuitry - must be low-impedance and tied to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| SCR-latchup immunity | Guaranteed robustness against latchup events in noisy industrial environments, per JEDEC JESD78. |
| Buffered TTL-compatible inputs | Accepts standard TTL logic levels without external biasing or level translation, simplifying interface design. |
| Balanced propagation delays | Minimizes skew between parallel flip-flop outputs, critical for synchronous bus interfaces and register files. |
| ±24 mA output drive | Directly drives 15 F-series logic loads or 50-Ω transmission lines, reducing need for external drivers. |
| Low power vs bipolar speed | Delivers AS/S-family switching performance while consuming significantly less quiescent current than bipolar equivalents. |
Applications
| Buffer/Storage Registers | Shift Registers |
|---|---|

IC Role / Device Role / Timing Role: State-holding element in deterministic finite-state machines - CLR initializes known state before test vector execution. Use Value: ±2000 V HBM ESD rating ensures reliability during repeated probe contact and board rework cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT174N | Same logic function, identical pinout, but offered in PDIP-16 (N) package with larger 19.3 mm × 9.4 mm footprint and higher RθJA (67°C/W). | Suitable for through-hole prototyping or legacy board designs; not recommended for space-constrained surface-mount production. | Select when manual soldering, breadboarding, or backward compatibility with existing PDIP layouts is required. |
| CD74HC174M96 | Same pinout and function but built on HC CMOS process: lower drive (±5.2 mA), slower max frequency (25 MHz), and wider VCC range (2–6 V). | Better suited for battery-powered or multi-supply systems where 5-V-only operation is not mandatory and speed is secondary. | Choose for ultra-low-power applications below 25 MHz where reduced IOH/IOL is acceptable and voltage flexibility is needed. |
Compared with SN74ACT174N, CD74ACT174M96 offers superior thermal performance in SOIC packaging and smaller PCB area; compared with CD74HC174M96, it delivers 3.6× higher clock rate and 4.6× stronger output drive at the cost of tighter 4.5–5.5 V supply constraint.

FAQ
What is the maximum clock frequency supported by CD74ACT174M96?
The CD74ACT174M96 supports a maximum clock frequency of 91 MHz over the –40°C to +85°C operating temperature range, as specified in the timing requirements table under recommended conditions (VCC = 5 V ± 0.5 V). At extended temperature (–55°C to +125°C), the limit reduces to 80 MHz. This rating assumes proper load capacitance (≤50 pF) and clean power delivery with local bypassing.
Does CD74ACT174M96 require external pull-up or pull-down resistors on unused inputs?
Yes - all unused inputs of CD74ACT174M96 must be tied to either VCC or GND to prevent floating nodes that could cause undefined logic states or increased power consumption. TI explicitly recommends this in Section 5.3 and Application Note SCBA004. The CD74ACT174M96 does not include internal termination, so external biasing is mandatory for reliable operation.
What is the meaning of the 'M96' suffix in CD74ACT174M96?
The 'M96' suffix in CD74ACT174M96 indicates a specific packaging and ordering variant: SOIC-16 (D package), supplied in large tape-and-reel format with 2500 units per reel, RoHS-compliant NiPdAu lead finish, and MSL Level-1 rating. It distinguishes this version from tube-packaged (e.g., CD74ACT174E) or WQFN-packaged (e.g., CD74ACT174BQBR) variants of the same logic function.
Can CD74ACT174M96 operate with a 3.3-V supply?
No - CD74ACT174M96 is not rated for 3.3-V operation. Its absolute minimum VCC is 4.5 V, and recommended operating range is strictly 4.5 V to 5.5 V. Attempting to power CD74ACT174M96 from 3.3 V will result in non-functional outputs, excessive propagation delay, or failure to meet setup/hold timing. For 3.3-V systems, consider the pin-compatible CD74LVC174 or SN74LVC174A.
Is CD74ACT174M96 pin-compatible with older CD74ACT174M variants?
Yes - CD74ACT174M96 is fully pin-compatible with earlier CD74ACT174M versions (e.g., obsolete CD74ACT174M), sharing identical SOIC-16 (D) package dimensions, pin numbering, and electrical interface. The '96' suffix denotes updated packaging logistics (tape-and-reel), not functional or mechanical revision. Layouts designed for CD74ACT174M remain valid for CD74ACT174M96.
