Product details
Overview
74LCX11MTC from ON Semiconductor is a low-voltage triple 3-input AND gate with 5V-tolerant inputs, designed for 2.3V–3.6V VCC operation in mixed-voltage systems. It delivers 6.0 ns max propagation delay at 3.3V, ±24 mA output drive at 3.0V, and power-down high-impedance I/O. It is used in voltage-level translation between 3.3V logic and legacy 5V buses in industrial control interfaces.
For engineers reviewing the 74LCX11MTC datasheet, pinout, applications, or equivalent options, key selection criteria include 5V input tolerance, TSSOP-14 package compatibility, sub-7 ns timing at 3.3V, ±24 mA drive strength, and JEDEC MO-153-compliant thermal and mechanical footprint.
Technical Context
The 74LCX11MTC implements three independent non-inverting 3-input AND functions with fully buffered outputs. Its CMOS design supports rail-to-rail input swing (0–5.5V) while operating from a 2.3–3.6V supply, enabling safe interfacing to both 3.3V logic domains and 5V signal sources without external level shifters.
All inputs and outputs enter high-impedance states during power-down (VCC = 0V), preventing back-driving and bus contention. Input leakage remains ≤±5.0 µA across full VI range (0–5.5V), and latch-up performance exceeds JEDEC 78 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V–3.6V - Enables direct use in 3.3V systems with margin for supply variation |
| Propagation Delay (tPD) | 6.0 ns max @ VCC = 3.3V, CL = 50pF - Supports >100 MHz toggle rates in combinatorial paths |
| Output Drive | ±24 mA @ VCC = 3.0V - Drives multiple LVTTL or LCX loads without buffering |
| Input Voltage Range | 0–5.5V - Accepts 5V logic signals safely while powered from 3.3V |
| Power-Down Leakage | 10 µA max @ VI/VO = 5.5V - Minimizes standby current in hot-swap or sleep-mode systems |
| ESD Rating | HBM > 2000V - Meets industrial handling robustness requirements without extra protection |
Pinout & Package
74LCX11MTC is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 4.4 mm wide, with 0.65 mm lead pitch. The package features gull-wing leads and exposed pad not connected internally (DAP = No Connect).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 5, 6, 7, 10, 11, 12 | A1/B1/C1, A2/B2/C2, A3/B3/C3 Inputs | Nine independent 5V-tolerant logic inputs grouped as three 3-input AND sets |
| 4, 8, 13 | O1, O2, O3 Outputs | Three buffered CMOS outputs capable of ±24 mA drive at 3.0V |
| 14 | VCC | Positive supply pin - must be decoupled locally due to fast switching transients |
| 7 | GND | Ground reference - shared return path for all three gates; layout requires low-inductance connection |
Key Features
| Feature | Design Value |
|---|---|
| 5V-tolerant inputs | Enables direct connection to 5V microcontrollers, FPGAs, or legacy peripherals without external level translators |
| Power-down high-Z I/O | Prevents signal contention and back-powering when VCC is off - critical for hot-plug and multi-rail power sequencing |
| Low dynamic noise | Proprietary EMI reduction circuitry minimizes simultaneous switching noise (SSN) in dense PCB layouts |
| JEDEC MO-153 TSSOP footprint | Ensures drop-in compatibility with standard SMT assembly lines and reflow profiles for 0.65 mm pitch |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC11PWR | Same 3.3V VCC, but only 5V-tolerant on inputs with VCC ≥ 2.7V; no power-down high-Z mode | Lacks true power-down isolation - unsuitable for hot-swap or multi-rail sequencing | Select when cost sensitivity outweighs need for power-state isolation |
| 74ALVC11MTCX | Higher speed (4.2 ns @ 3.3V), same TSSOP-14 package, but only 3.6V max input rating - not 5V tolerant | Cannot interface directly to 5V sources; requires external clamping or translation | Select only in pure 3.3V systems requiring tighter timing margins |
Compared with SN74LVC11PWR and 74ALVC11MTCX, the 74LCX11MTC uniquely combines guaranteed 5V input tolerance, power-down high-Z, and sub-7 ns delay in a JEDEC MO-153 TSSOP - making it the only choice for robust mixed-voltage AND logic in industrial and automotive contexts requiring fail-safe power sequencing.

FAQ
What is the maximum input voltage the 74LCX11MTC can tolerate?
The 74LCX11MTC supports DC input voltages from –0.5V to +5.5V regardless of VCC level, enabling safe interfacing with 5V logic families while operating from a 2.3–3.6V supply. This 5V tolerance is guaranteed per datasheet Section "Recommended Operating Conditions" and does not require external clamping diodes or resistors when used within absolute maximum ratings.
Does the 74LCX11MTC support power-down isolation?
Yes, the 74LCX11MTC enters a high-impedance state on all inputs and outputs when VCC = 0V, preventing back-driving and bus contention during power sequencing or hot-swap events. This behavior is explicitly documented in the "Features" section and verified in the "DC Electrical Characteristics" table under IOFF (power-off leakage current ≤10 µA).
What is the propagation delay of the 74LCX11MTC at 3.3V supply?
The 74LCX11MTC has a maximum propagation delay (tPHL/tPLH) of 6.0 ns at VCC = 3.3V ± 0.3V, CL = 50pF, and TA = –40°C to +85°C. This value is measured per JEDEC-standard AC test conditions and appears in the "AC Electrical Characteristics" table of the official Rev. 1.6.1 datasheet.
Which package type does the 74LCX11MTC use?
The 74LCX11MTC uses a 14-lead Thin Shrink Small Outline Package (TSSOP) conforming to JEDEC MO-153, variation AB, with 4.4 mm body width and 0.65 mm lead pitch. Mechanical dimensions, land pattern recommendations, and tape-and-reel specifications are provided in the "Ordering Information" and "Package Drawing" sections of the datasheet.
Can the 74LCX11MTC drive multiple LVTTL loads?
Yes, the 74LCX11MTC delivers ±24 mA output drive at VCC = 3.0V, sufficient to drive up to 10 LVTTL inputs (each requiring ~0.4 mA) or 3–4 LCX/LVCMOS loads simultaneously. This capability is confirmed in the "DC Electrical Characteristics" table under IOH/IOL specifications and enables fanout without external buffers in most system-level designs.
