Product details
Overview
MC74HC11ADTG from onsemi is a triple 3-input AND gate in high-performance silicon-gate CMOS technology, pin-compatible with LS11 logic. It operates from 2.0 V to 6.0 V, delivers ±25 mA output drive per pin, exhibits 10 LSTTL load capability, and supports industrial temperature range (–55 °C to +125 °C) - used in digital control logic, address decoding, and enable gating in embedded microcontroller systems.
For engineers reviewing the MC74HC11ADTG datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage flexibility (2.0–6.0 V), propagation delay (16 ns at 6.0 V), input compatibility with TTL/CMOS, automotive qualification (AEC-Q100 option), and TSSOP-14 package suitability for space-constrained PCB layouts.
Technical Context
The MC74HC11ADTG implements three independent 3-input AND functions (Y = A·B·C) using standard CMOS logic architecture. Each gate features symmetrical input thresholds (VIH = 4.2 V, VIL = 1.8 V at VCC = 6.0 V) and rail-to-rail output swing with guaranteed VOH ≥ 5.9 V and VOL ≤ 0.1 V under light load.
It supports direct interfacing to TTL, NMOS, and CMOS families without level-shifting, thanks to LSTTL-compatible input current limits (±20 mA clamp) and 10 LSTTL load drive capability. Input leakage remains ≤ ±1.0 µA at 6.0 V, and AC performance is characterized up to 125 °C with tPLH/tPHL = 25 ns max at VCC = 6.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Three independent 3-input AND gates (Y1 = A1·B1·C1, Y2 = A2·B2·C2, Y3 = A3·B3·C3) |
| Supply Voltage Range | 2.0 V to 6.0 V - enables interoperability across 3.3 V and 5 V logic domains without voltage translation |
| Propagation Delay | 16 ns max (A/B/C to Y, VCC = 6.0 V, TA = 25 °C) - supports >30 MHz toggle rates in synchronous logic paths |
| Output Drive | ±25 mA DC per pin - sufficient to directly drive LED indicators or small logic loads without buffers |
| Input Compatibility | LSTTL-compatible with pullup resistors; CMOS-output compatible without external components |
| Operating Temperature | –55 °C to +125 °C - qualified for under-hood automotive, industrial control, and extended-environment applications |

Pinout & Package
TSSOP-14 package (Case 948G), 4.9 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | A1, B1, C1 inputs | First AND gate inputs - all three must be HIGH to assert Y1 HIGH |
| 4, 5, 6 | A2, B2, C2 inputs | Second AND gate inputs - electrically isolated from Gate 1 and Gate 3 |
| 9, 10, 11 | A3, B3, C3 inputs | Third AND gate inputs - no internal connection to other gates |
| 7 | GND | Ground reference for all logic and power domains - must be low-impedance connection |
| 8 | Y1 output | Active-HIGH output of first AND gate - drives downstream logic or indicator loads |
| 12 | Y2 output | Active-HIGH output of second AND gate - independent timing and loading behavior |
| 13 | Y3 output | Active-HIGH output of third AND gate - shares same VCC/GND but no signal coupling |
| 14 | VCC | Positive supply rail - bypassing with 0.1 µF ceramic capacitor near pin is mandatory for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Triple 3-input AND logic | Enables compact implementation of multi-condition enable signals (e.g., CPU address decode with chip select + read/write + valid) |

| 10 LSTTL load drive | Directly drives legacy TTL bus lines or multiple CMOS inputs without fanout buffers |
| AEC-Q100 qualified variant available | Supports automotive applications requiring PPAP documentation and controlled change management (MC74HC11ADTR2G−Q) |

Use Scenario: Enabling discrete output drivers only when safety interlocks, power status, and command validity are all asserted. IC Role / Device Role / Timing Role: Logic-level AND gate performing real-time hardware-enforced safety gating before actuator activation. Use Value: Prevents unintended actuation by requiring simultaneous assertion of three independent conditions - implemented with deterministic, zero-software-latency hardware logic. |
Use Scenario: Controlling headlight relay activation only when ignition ON, headlight switch ON, and ambient light sensor output is LOW. IC Role / Device Role / Timing Role: Combinational logic element generating headlight enable signal from three vehicle bus or analog-derived digital inputs. Use Value: Provides fail-safe lighting control independent of ECU software state - critical for functional safety compliance in ASIL-B systems. |
| Medical Device Power Sequencing | Test Equipment Signal Conditioning |
|
Use Scenario: Gating power-enable signals to sub-systems (e.g., display, sensor interface, comms) only after main supply rails stabilize and watchdog confirms firmware integrity. IC Role / Device Role / Timing Role: Hardware-based power-up coordination logic ensuring strict sequencing before system initialization proceeds. Use Value: Eliminates race conditions during cold start by enforcing hardware-level dependency between power, reset, and firmware readiness signals. |
Use Scenario: Validating test probe connection, instrument ready status, and user-trigger confirmation before initiating calibration sequence. IC Role / Device Role / Timing Role: Synchronization gate ensuring all preconditions are met prior to high-precision measurement capture. Use Value: Prevents invalid calibration data acquisition by blocking trigger propagation until three independent readiness flags are active. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC11DR | SOIC-14 package only; identical electrical specs and pinout; no AEC-Q100 variant offered | Preferred for through-hole prototyping or legacy board designs using SOIC footprint | Select when board layout uses SOIC-14 and automotive qualification is not required |
| 74VHC11M | Faster propagation delay (10 ns @ 5 V); higher ICC (100 µA typical); same TSSOP-14 footprint | Better suited for high-speed clock gating or data path conditioning where sub-15 ns latency is critical | Select when speed outweighs quiescent current budget, and VHC family compatibility is acceptable |
Compared with SN74HC11DR and 74VHC11M, the MC74HC11ADTG offers unique value in TSSOP-14 space-constrained designs with optional AEC-Q100 qualification - enabling drop-in use in both industrial and automotive modules without layout revision, while maintaining industry-standard HC logic behavior and supply flexibility.

FAQ
What is the maximum operating frequency supported by the MC74HC11ADTG?
The MC74HC11ADTG does not specify a maximum clock frequency because it is a combinational logic device without internal clocking. Its usable toggle rate depends on propagation delay and system-level timing margins. At VCC = 6.0 V, tPLH/tPHL is 16 ns max, supporting reliable operation in logic paths with >30 MHz signal transitions - verified across –55 °C to +125 °C.
Is the MC74HC11ADTG pin-compatible with the older 74LS11?
Yes, the MC74HC11ADTG is explicitly designed to be pin-compatible with the 74LS11, sharing identical pin assignments for all inputs, outputs, VCC, and GND. This allows direct replacement in existing LS-based designs while upgrading to CMOS benefits: wider supply range (2.0–6.0 V), lower power, and higher noise immunity - confirmed in the onsemi datasheet Rev. 4, page 1.
Does the MC74HC11ADTG require external pull-up resistors on its inputs?
No, the MC74HC11ADTG inputs are CMOS-compatible and do not require external pull-ups for normal operation. However, the datasheet states that with pull-up resistors, inputs become compatible with LSTTL outputs - meaning pull-ups are optional and only needed when interfacing with open-collector LSTTL sources, not for standard CMOS or MCU GPIO driving.
What is the thermal resistance (θJA) of the MC74HC11ADTG in its TSSOP-14 package?
The MC74HC11ADTG in TSSOP-14 (Case 948G) has a junction-to-ambient thermal resistance (θJA) of 150 °C/W, measured on an FR4 board with minimum pad spacing and no airflow (per JESD51-7). This value informs thermal design for continuous operation at elevated ambient temperatures - especially relevant in sealed enclosures or stacked PCB assemblies.
Can unused inputs on the MC74HC11ADTG be left floating?
No, unused inputs on the MC74HC11ADTG must never be left floating. The datasheet explicitly requires all unused inputs to be tied to a defined logic level - either VCC or GND - to prevent erratic switching, increased power consumption, and potential damage due to undefined input voltages. Floating inputs can cause oscillation and excessive ICC, degrading reliability.
