Product details

Overview

74LCX11M from ON Semiconductor is a low-voltage triple 3-input AND gate with 5V-tolerant inputs, designed for 2.3V–3.6V V_CC operation in mixed-voltage systems. It delivers 6.0ns max propagation delay at 3.3V, ±24mA output drive at 3.0V, and power-down high-impedance I/O states. It is used in voltage-level translation between 3.3V logic and legacy 5V peripherals in industrial control backplanes.

For engineers reviewing the 74LCX11M datasheet, pinout, applications, or equivalent options, key selection criteria include 5V input tolerance, SOIC-14 package compatibility, sub-7ns AC performance at 3.3V, quiescent current ≤10µA, and JEDEC MS-012 mechanical compliance.

Technical Context

The 74LCX11M implements three independent non-inverting AND gates with fully buffered outputs and CMOS-compatible input thresholds. Each gate accepts inputs up to 5.5V while operating from a 2.3–3.6V supply, enabling safe interfacing with higher-voltage signal sources without external level shifters.

Its architecture includes power-down protection circuitry that places both inputs and outputs in high-impedance state when V_CC = 0V, preventing back-driving of powered subsystems. Propagation delay skew between outputs is specified at ≤1.0ns, supporting synchronous multi-gate timing-critical paths.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.3V–3.6V - Enables direct integration into 3.3V digital subsystems without regulator overhead.
Input Voltage Tolerance	0V–5.5V - Allows connection to 5V TTL/CMOS outputs without clamping diodes or resistors.
t_PD Max	6.0ns @ V_CC = 3.3V, C_L = 50pF - Supports >100MHz toggle rates in combinatorial logic paths.
I_OH/I_OL	±24mA @ V_CC = 3.0V - Drives 10+ LVC/LCX loads or short PCB traces without buffering.
I_CC Max	10µA @ V_CC = 3.3V, all inputs static - Minimizes standby power in battery-backed or energy-sensitive modules.
Input Leakage	±5.0µA @ V_CC = 2.3–3.6V - Ensures reliable HIGH/LOW detection even with high-impedance pull-ups/downs.

Pinout & Package

74LCX11M is housed in a 14-lead SOIC (JEDEC MS-012, 0.150" narrow body) with standard dual-inline pin spacing (1.27mm pitch) and 1.75mm max height. The package is lead-free per JEDEC J-STD-020B and compatible with reflow soldering profiles.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 13	A1, A2, A3 Inputs	First input of each AND gate - accepts 0–5.5V signals regardless of V_CC.
3, 4, 12	B1, B2, B3 Inputs	Second input of each AND gate - electrically identical to A pins; no internal differentiation.
5, 6, 11	C1, C2, C3 Inputs	Third input of each AND gate - supports same 5V-tolerant operation and threshold specs as A/B pins.
7	GND	Ground reference for all logic and output stages - must be connected before V_CC during power-up.
8, 9, 10	Y1, Y2, Y3 Outputs	Active-HIGH AND outputs - drive to V_CC or GND with rail-to-rail swing and ±24mA capability.
14	V_CC	Positive supply for internal logic and output drivers - must be 2.3–3.6V; not tolerant to overvoltage.

Key Features

Feature	Design Value
5V-tolerant inputs	Enables direct interface to 5V microcontrollers, EEPROMs, or legacy peripherals without external level translators.
Power-down high-Z I/O	Prevents current leakage and bus contention when V_CC is unpowered, critical for hot-swap or partial-power-down systems.
Low dynamic power dissipation	CPD = 25pF @ 3.3V enables <1mW average power at 10MHz toggle rate - suitable for portable instrumentation.
JEDEC-compliant SOIC footprint	Matches industry-standard land pattern SOIC127P600X145-14M - ensures drop-in replacement and PCB reuse across logic families.
ESD robustness	HBM >2000V and MM >200V - reduces need for external ESD protection in industrial panel interfaces.

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
SN74LVC11APWR	Lower V_CC min (1.65V), tighter t_PD spec (5.2ns), but only 3.6V input tolerance - not 5V-tolerant.	Requires external clamping for 5V inputs; unsuitable where legacy 5V signals connect directly.	Select when system operates ≥2.7V and all inputs are ≤3.6V; avoid if interfacing to true 5V logic.
74AHC11D,118	Wider V_CC range (2.0–5.5V), higher speed (4.5ns), but no guaranteed 5V input tolerance at V_CC < 4.5V.	Input tolerance degrades below V_CC = 4.5V; may require derating or validation for 5V inputs at 3.3V supply.	Prefer for 5V-native systems; verify VIH/VIL margins at actual V_CC before using in mixed-voltage designs.

Compared with SN74LVC11APWR and 74AHC11D,118, the 74LCX11M uniquely guarantees 5V input tolerance across its full 2.3–3.6V V_CC range without external components, making it the only drop-in solution for retrofitting 5V signal paths into 3.3V logic subsystems.

FAQ

What is the maximum input voltage the 74LCX11M can tolerate?

The 74LCX11M supports DC input voltages from –0.5V to +5.5V regardless of V_CC level, as confirmed in the Absolute Maximum Ratings table. This 5V tolerance applies across its entire recommended operating range (2.3V–3.6V), enabling direct connection to 5V TTL or CMOS outputs without risk of damage or latch-up.

Does the 74LCX11M support power-down mode?

Yes, the 74LCX11M features power-down high-impedance inputs and outputs. When V_CC = 0V, all I/O pins enter a high-Z state, preventing back-current flow into powered sections of the system. This behavior is explicitly documented in the Features section and verified in the DC Electrical Characteristics table under IOFF (power-off leakage).

What is the propagation delay of the 74LCX11M at 3.3V supply?

The 74LCX11M has a maximum propagation delay (t_PHL/t_PLH) of 6.0ns when operated at V_CC = 3.3V ±0.3V with C_L = 50pF, as specified in the AC Electrical Characteristics table. Typical delay is lower (1.5ns), but design margins must use the 6.0ns worst-case value for timing closure.

Is the 74LCX11M pin-compatible with other 74-series triple AND gates?

The 74LCX11M uses the standard 14-pin SOIC layout matching the 74LS11, 74HC11, and 74AHC11 pinouts: inputs on pins 1/2/13 (A1), 3/4/12 (B1), 5/6/11 (C1); outputs on pins 8/9/10 (Y1/Y2/Y3); V_CC on pin 14 and GND on pin 7. Mechanical and electrical pin mapping is identical - though voltage and timing specs differ.

What package type does the 74LCX11M use?

The 74LCX11M is supplied in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, designated M14A in ON Semiconductor's ordering information. It measures 8.75mm × 4.00mm × 1.75mm max and uses 1.27mm lead pitch - fully compatible with standard SOIC-14 footprints and reflow profiles.
