Product details
Overview
M74HC11TTR from STMicroelectronics is a high-speed CMOS triple 3-input AND gate in TSSOP-14 package, operating from 2V to 6V supply, with typical propagation delay of 9ns at 6V and quiescent current ≤1µA at 25°C; used for digital logic combining in industrial control timing paths and sensor signal conditioning interfaces.
For engineers reviewing the M74HC11TTR datasheet, M74HC11TTR pinout, M74HC11TTR application, or M74HC11TTR equivalent, key selection factors include VCC range (2–6V), symmetrical output drive (±4mA), noise immunity (28% VCC), propagation delay matching (tPLH ≅ tPHL), and TSSOP-14 thermal and board-space constraints.
Technical Context
The M74HC11 implements three independent 3-input AND functions using silicon gate C2MOS technology with four-stage buffered output architecture, enabling stable switching and high noise immunity. Each input includes protection against ESD and transient overvoltage, and all outputs exhibit matched rise/fall times (tTLH/tTHL ≤22ns at 6V).
It operates across an extended temperature range (–55°C to +125°C) with rail-to-rail input/output voltage compatibility (VI, VO = 0 to VCC) and supports input transition times up to 1000ns at 2V, ensuring robustness in noisy embedded environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2V to 6V - Enables direct interface with 3.3V and 5V logic domains without level shifters. |
| tPD (Typ.) | 9ns at VCC = 6V - Supports >50MHz toggle rates in combinatorial logic paths. |
| IOL / IOH | ±4mA min - Drives standard 74HC loads or multiple CMOS inputs without fanout limitation. |
| VNIH / VNIL | 28% VCC min - Rejects common-mode noise up to ±1.68V on 6V rails. |
| ICC (Max) | 1µA at TA = 25°C - Suitable for battery-backed or ultra-low-power standby states. |
| Operating Temp | –55°C to +125°C - Qualified for under-hood automotive and industrial motor control enclosures. |
| CIN | 5–10pF - Minimizes capacitive loading on driving gates and preserves signal edge integrity. |
Pinout & Package
TSSOP-14 (Thin Shrink Small Outline Package), 4.9 × 6.4 mm body, 0.65 mm pitch, 14-pin surface-mount, JEDEC MO-153 compliant, with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 9 | 1A, 2A, 3A - Input A of each AND gate | Three independent 3-input logic channels; pin 1 is Gate 1 Input A, pin 3 is Gate 2 Input A, pin 9 is Gate 3 Input A. |
| 2, 4, 10 | 1B, 2B, 3B - Input B of each AND gate | Second input per gate; routed separately to support asynchronous enable/control signals. |
| 13, 5, 11 | 1C, 2C, 3C - Input C of each AND gate | Third input per gate; allows full 3-input conjunction without external wiring. |
| 12, 6, 8 | 1Y, 2Y, 3Y - Output of each AND gate | Active-high open-drain compatible outputs; each drives one logic net independently. |
| 7 | GND | Dedicated ground reference for internal biasing and noise rejection; must be low-inductance connection. |
| 14 | VCC | Single positive supply for all three gates; decoupling capacitor required within 5mm. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | |IOH| = IOL ≥ 4mA - Ensures matched rise/fall times and eliminates duty-cycle distortion in clocked logic. |
| Balanced propagation delays | tPLH ≅ tPHL - Prevents pulse-width narrowing in cascaded AND-based timing circuits. |
| High noise immunity | VNIH/VNIL = 28% VCC min - Maintains logic integrity in 12V automotive harness proximity or motor-drive EMI zones. |
| Wide supply range | VCC = 2V to 6V - Interoperates with legacy 5V systems and modern 3.3V/2.5V microcontrollers without translation. |
| ESD-protected inputs | ±20mA diode current rating - Survives handling and board-level transients per IEC 61000-4-2 Level 2. |
Applications
| Industrial PLC Input Conditioning | Automotive Body Control Module Logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC11DR | SOP-14 package; slightly higher ICC (2µA max); identical AC specs and pinout. | Larger footprint; less suitable for high-density PCBs or thermal-constrained enclosures. | Select when SOP-14 is preferred for manual assembly or legacy reflow profiles. |
| 74LVC11PW | 3.3V-only operation (1.65–3.6V); lower VCC tolerance; 24mA drive; different pin assignment (non-pin-compatible). | Not usable in 5V systems; requires level-shifting if interfacing with 5V peripherals. | Select only for pure 3.3V designs where higher drive strength justifies redesign effort. |
Compared with SN74HC11DR and 74LVC11PW, the M74HC11TTR uniquely balances 2–6V interoperability, TSSOP-14 space efficiency, and sub-10ns timing-making it optimal for mixed-voltage industrial modules requiring compact, thermally efficient logic integration.

FAQ
Is M74HC11TTR pin-compatible with standard 74-series 11 logic?
Yes, M74HC11TTR is functionally and pin-compatible with the industry-standard 74LS11 and 74HC11 in TSSOP-14. Pin assignments for inputs (1A–3C) and outputs (1Y–3Y) match JEDEC MS-012 and MO-153 layouts, enabling drop-in replacement where voltage and speed requirements align.
What is the maximum capacitive load this device can drive reliably?
M74HC11TTR is characterized for CL = 50pF in AC testing, and its output drive (±4mA) supports loads up to ~75pF while maintaining tPLH/tPHL <22ns at 6V. For loads exceeding 50pF, add series termination or verify timing margins using the device's CPD = 26pF and ICC(opr) = CPD × VCC × fIN + ICC/3 formula.
Does M74HC11TTR support partial power-down or I/O isolation when VCC = 0V?
No. M74HC11TTR does not feature Ioff or power-down isolation. When VCC = 0V, inputs and outputs may sink current through internal protection diodes if voltages exceed GND–0.5V or VCC+0.5V. External series resistors or isolation switches are required for hot-swap or multi-rail backplane applications.
Can this device operate at 1.8V supply?
No. The recommended minimum VCC is 2.0V per datasheet Section 2. Absolute operation below 2.0V is not guaranteed: VIH drops to 1.5V at 2V, and output drive collapses below specification. For 1.8V systems, consider 74LVC11 or 74AUP1G08 variants explicitly rated down to 1.65V.
