Product details
Overview
CD74ACT00M from Texas Instruments is a quadruple 2-input positive-NAND gate IC in SOIC-14 package, operating at 4.5–5.5 V supply, delivering ±24 mA output drive, 3.4–9.5 ns propagation delay (tPLH/tPHL), and TTL-voltage-compatible inputs for logic-level interfacing in industrial control and digital signal conditioning circuits.
For engineers reviewing the CD74ACT00M datasheet, CD74ACT00M pinout, CD74ACT00M application, or CD74ACT00M equivalent, key selection criteria include its CMOS ACT-family speed-power balance, SCR-latchup resistance, 2 kV HBM ESD rating, and compatibility with legacy TTL input thresholds in mixed-logic systems.
Technical Context
The CD74ACT00M implements four independent NAND gates (Y = A • B) using advanced CMOS process technology, enabling bipolar-F/AS/S-speed performance with significantly reduced static and dynamic power versus bipolar equivalents. Its balanced tPLH/tPHL ensures symmetrical rise/fall timing critical for clocked logic and state-machine design.
Each gate features TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V), supports fanout to 15 F-series devices, and operates across –55°C to +125°C ambient temperature. The device is SCR-latchup resistant and rated per MIL-STD-883 method 3015 for electrostatic discharge.

| Output Drive | ±24 mA - Sufficient to directly drive multiple TTL loads or small capacitive buses without buffering. |
| Propagation Delay | 3.4–9.5 ns - Enables reliable operation up to ~100 MHz toggle rate in non-critical timing paths. |
| Input Thresholds | VIH = 2 V, VIL = 0.8 V - Guarantees interoperability with 5 V TTL outputs and robust noise margin. |
| ESD Rating | ±2000 V HBM - Meets industrial handling requirements without additional protection circuitry. |
| Power Dissipation | 45 pF Cpd - Predictable dynamic power consumption for thermal modeling in dense PCB layouts. |
| Operating Temp | –55°C to +125°C - Qualified for extended-temperature industrial, aerospace, and automotive under-hood applications. |
Pinout & Package
CD74ACT00M is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package with 8.65 mm × 6 mm footprint and 1.75 mm max height, compatible with standard surface-mount reflow processes (MSL Level-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 1B | Input | First NAND gate inputs - Must be tied to VCC or GND if unused to prevent floating-induced instability. |
| 1Y | Output | First NAND gate output - Capable of sourcing/sinking ±24 mA with rail-to-rail swing. |
| 2A, 2B, 2Y | Input/Output | Second NAND gate terminals - Electrically identical to 1A/1B/1Y; no internal coupling. |
| 3A, 3B, 3Y | Input/Output | Third NAND gate terminals - Independent function; pin 8 is output, not ground. |
| 4A, 4B, 4Y | Input/Output | Fourth NAND gate terminals - Pin 11 is output; pins 12/13 are inputs. |
| GND (Pin 7) | Ground Reference | Primary return path for all gates - Requires low-inductance connection to system ground plane. |
| VCC (Pin 14) | Power Supply | 5 V supply input - Requires local 0.1 µF bypass capacitor placed adjacent to pin for noise suppression. |
| NC | No Connection | No internal connection - Left unpopulated; no routing or termination required. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-Voltage Compatibility | Accepts standard 5 V TTL logic levels (0.8 V/2.0 V thresholds) while consuming CMOS power - eliminates level-shifter need in hybrid systems. |
| Balanced Propagation Delays | tPLH and tPHL match within 1.5 ns across temperature - reduces skew in synchronous logic trees and enables predictable setup/hold timing. |
| ±24 mA Output Drive | Drives 15 F-series loads or 50 Ω transmission lines - supports direct interface to bus structures and moderate-capacitance nodes. |
| SCR-Latchup Resistance | Qualified per JEDEC JESD78 - prevents destructive latchup during overvoltage transients or hot-insertion events in powered-backplane systems. |
| 2 kV HBM ESD Protection | Exceeds MIL-STD-883 method 3015 - reduces field failure risk during board assembly and handling without external TVS diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT00DR | Same ACT family, identical electrical specs, SOIC-14 package, but TI's current production part with MSL Level-1 and RoHS-compliant NIPDAU finish. | Identical functional replacement; differs only in packaging date code and lifecycle status - CD74ACT00M is obsolete, SN74ACT00DR is active. | Select SN74ACT00DR for new designs requiring long-term supply assurance and updated manufacturing compliance. |
| 74ACT00PC | PDIP-14 package variant (N), same logic function and specs, but through-hole mounting and wider body (19.3 mm × 9.4 mm). | Suitable for prototyping, legacy repair, or through-hole assembly - lacks surface-mount thermal performance and board density advantages. | Choose 74ACT00PC only when PDIP form factor is mandatory; otherwise prefer SOIC for automated assembly and thermal efficiency. |
Compared with CD74ACT00M, SN74ACT00DR offers identical functionality with assured availability and updated process controls, while 74ACT00PC provides mechanical compatibility for hand-soldered or legacy PCBs - neither is pin-compatible with CD74ACT00M in terms of lifecycle or packaging, but both deliver equivalent logic behavior and electrical performance.

FAQ
What is the operating temperature range specified for the CD74ACT00M?
The CD74ACT00M is rated for operation from –55°C to +125°C ambient temperature, making it suitable for harsh-environment applications including aerospace, automotive under-hood systems, and industrial automation where thermal extremes are encountered. This range is confirmed in Section 4.3 of the official TI datasheet SCHS308C and applies specifically to the CD74ACT00M SOIC-14 variant.
Does the CD74ACT00M require external pull-up or pull-down resistors on unused inputs?
Yes - all unused inputs of the CD74ACT00M must be tied to either VCC or GND to prevent floating states that cause excessive current draw, oscillation, or undefined logic behavior. TI explicitly recommends this in Section 7.2.1 of the datasheet; leaving inputs unconnected violates recommended operating conditions and risks reliability degradation.
What is the maximum output current capability of the CD74ACT00M, and how is it defined?
The CD74ACT00M delivers ±24 mA output current per gate, verified at VCC = 4.5 V and TA = –40°C to +85°C (Section 4.3). This value represents guaranteed sink/source capability while maintaining VOL ≤ 0.44 V and VOH ≥ 3.8 V - sufficient to drive 15 F-series logic loads or terminate 50 Ω transmission lines without external buffers.
Is the CD74ACT00M pin-compatible with other members of the CDx4ACT00 family such as CD74ACT00E or CD54ACT00F3A?
Yes - the CD74ACT00M shares identical pinout and logic function with CD74ACT00E (PDIP-14) and CD54ACT00F3A (CDIP-14), as confirmed in Figure 3-1 and Table 3-1 of the datasheet. However, package dimensions, thermal resistance (RθJA), and temperature ratings differ: CD74ACT00M is SOIC-14 (–55°C to +125°C), CD74ACT00E is PDIP-14 (same temp range), and CD54ACT00F3A is CDIP-14 (–55°C to +125°C).
What does the "ACT" designation signify in CD74ACT00M, and how does it differ from standard 74HC or 74LS logic?
The "ACT" in CD74ACT00M denotes Texas Instruments' Advanced CMOS Technology - a logic family combining bipolar-speed propagation delays (comparable to 74F/74AS) with CMOS power efficiency and TTL-compatible input thresholds. Unlike 74HC (higher impedance, CMOS-only thresholds) or 74LS (bipolar, higher power), CD74ACT00M achieves 3.4 ns tPLH at 24 mA drive with <80 μA ICC, enabling direct TTL interfacing without level shifters.
