Product details
Overview
MC74ACT11NG from onsemi is a triple 3-input AND gate in high-performance silicon-gate CMOS technology, designed for digital logic interfacing and signal conditioning in industrial control and embedded systems. It features TTL-compatible inputs, 24 mA output drive capability, 5.0 V nominal supply operation, and operates across −40°C to +85°C ambient temperature.
For engineers reviewing the MC74ACT11NG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, SOIC-14 package details, real-world use cases in bus gating and enable logic, and validated alternative parts with documented functional and voltage-level differences.
Technical Context
The MC74ACT11NG implements three independent 3-input AND functions using CMOS transistor pairs with buffered outputs. Its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5.0 V) allow direct interfacing with legacy 5 V TTL logic families without level-shifting.
Propagation delay is specified at 1.5 ns (typ) to 10.5 ns (max) under 50 pF load at 5.0 V, supporting reliable operation in synchronous digital subsystems up to ~50 MHz clock domains. Input capacitance is 4.5 pF and power dissipation capacitance is 20 pF, enabling low dynamic power consumption in high-speed switching applications.

FAQ
What logic family does the MC74ACT11NG belong to, and how does it differ from standard 74AC devices?
The MC74ACT11NG belongs to the 74ACT (Advanced CMOS TTL-compatible) family. Unlike standard 74AC devices, it features TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at 5 V), allowing direct connection to legacy TTL outputs without level shifters-whereas 74AC inputs require higher VIH (≥ 3.15 V at 5 V). This makes MC74ACT11NG ideal for upgrading older 5 V systems while retaining full signal integrity.
Can the MC74ACT11NG operate at 3.3 V supply voltage?
No, the MC74ACT11NG is not rated for 3.3 V operation. Its recommended supply range is strictly 4.5 V to 5.5 V, and its TTL-compatible input thresholds are only guaranteed within that range. Attempting 3.3 V operation may result in undefined logic states, increased propagation delay, or failure to recognize HIGH inputs-use MC74VHC11 or similar 3.3 V-optimized logic for such applications.
What is the maximum capacitive load the MC74ACT11NG can drive reliably?
The MC74ACT11NG is characterized for CL = 50 pF in AC specifications, with propagation delay and output swing guaranteed under that load. While it can drive higher capacitance (e.g., 100–150 pF) with reduced speed, signal integrity degrades beyond 50 pF due to increased rise/fall times and potential ringing. For loads exceeding 50 pF, add series termination or buffer stages-especially critical in MC74ACT11NG-based clock or strobe distribution networks.
Does the MC74ACT11NG have any built-in ESD protection, and what is its rating?
Yes, the MC74ACT11NG includes on-die ESD protection structures. It is rated to >2000 V per Human Body Model (HBM) and >1000 V per Charged Device Model (CDM), per JESD22-A114 and JESD22-C101 standards. These ratings meet standard handling requirements for board assembly but do not eliminate need for ESD-safe workstations during manual handling or rework of MC74ACT11NG-equipped PCBs.
How many independent logic functions does the MC74ACT11NG provide, and how are they arranged?
The MC74ACT11NG provides three completely independent 3-input AND functions in a single SOIC-14 package. Each gate has dedicated inputs (Gate 1: pins 1/2/13; Gate 2: pins 4/5/6; Gate 3: pins 9/10/11) and its own output (Y1: pin 3; Y2: pin 8; Y3: pin 12), with no shared internal nodes-enabling concurrent, isolated logic operations essential in MC74ACT11NG-based system control and safety interlock circuits.
