Product details
Overview
74VCX00MTCX from onsemi (formerly Fairchild Semiconductor) is a low-voltage quad 2-input NAND gate IC designed for level-shifting logic interfacing in mixed-supply systems. It operates from 1.2V to 3.6V VCC, supports 3.6V-tolerant inputs/outputs, delivers ≤2.8ns propagation delay at 3.3V, and provides ±24mA drive strength at 3.0V - enabling robust signal conditioning in portable and battery-powered digital control circuits.
For engineers reviewing the 74VCX00MTCX datasheet, pinout, applications, or equivalent options, key selection considerations include its 3.6V I/O tolerance across 1.2V–3.6V supply range, power-off high-impedance behavior, JEDEC MO-153 TSSOP-14 package, and compatibility with 1.8V/2.5V/3.3V logic families in voltage-translating gate arrays.
Technical Context
The 74VCX00MTCX implements four independent 2-input NAND gates using advanced CMOS process technology optimized for speed-power trade-off in low-voltage operation. Its input structure enables safe interfacing between higher-voltage peripherals (up to 3.6V) and lower-core-supply logic domains (as low as 1.2V), without external level shifters.
All inputs and outputs maintain high-impedance state when VCC = 0V, preventing back-driving of powered subsystems. Propagation delay is specified under defined load conditions (CL = 30pF, RL = 500Ω), and output skew remains ≤0.5ns across all gate pairs at 3.3V, supporting timing-critical combinational logic paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.2V to 3.6V - enables direct use in 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V logic domains without level translation circuitry |
| I/O Voltage Tolerance | 3.6V - allows connection to 3.3V or 3.6V buses while powered from lower VCC, eliminating risk of overvoltage damage |
| tPD Max | 2.8ns at VCC = 3.3V, CL = 30pF - supports >350MHz toggle rates in critical path logic stages |
| IOH/IOL | ±24mA at VCC = 3.0V - drives standard TTL loads or multiple CMOS inputs without buffering |
| Power-Off High-Z | Inputs and outputs enter high-impedance state when VCC = 0V - prevents current leakage and bus contention during power sequencing |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control and communications equipment |
| ESD Rating | HBM >2000V - meets standard reliability requirements for handling and board assembly without special ESD controls |
Pinout & Package
74VCX00MTCX is packaged in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 4.4mm wide, with gull-wing leads and exposed pad not connected internally (DAP = No Connect). The package supports fine-pitch PCB layout and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | Gate Inputs (A1/B1, A2/B2, A3/B3, A4/B4) | Four independent NAND gate input pairs - each pair accepts 3.6V-tolerant logic signals regardless of VCC level |
| 3, 6, 10, 11 | Gate Outputs (Y1, Y2, Y3, Y4) | Active-low NAND outputs - drive 3.6V-tolerant loads and interface directly with higher-voltage logic families |
| 7 | GND | Ground reference for all internal circuitry and I/O structures - must be connected to system ground plane |
| 14 | VCC | Primary power supply - sets logic threshold and output drive strength; supports 1.2V–3.6V operation |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC operating range | 1.2V to 3.6V - eliminates need for separate voltage regulators in multi-rail digital subsystems |
| 3.6V-tolerant I/O | Enables direct connection to 3.3V peripherals while core logic runs at 1.8V - reduces BOM count and board space |
| Power-off high-impedance I/O | Prevents back-powering and bus contention during hot-swap or partial-power-down sequences - improves system robustness |
| Low dynamic noise | Proprietary EMI reduction circuitry minimizes switching noise coupling into adjacent analog or RF sections - verified in TSSOP layout |
| JEDEC-compliant TSSOP | MO-153 footprint - ensures compatibility with standard SMT assembly lines and IPC-7351 land patterns |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC00APW | Same 14-pin TSSOP package; 1.65V–3.6V VCC; 3.6V-tolerant I/O; tPD = 3.7ns max at 3.3V | Larger minimum VCC (1.65V vs. 1.2V) - unsuitable for sub-1.65V ultra-low-power designs | Select when full 1.65V–3.6V operation suffices and TI's qualification profile is preferred |
| 74AUP00GW | 1.1V–3.6V VCC; 3.3V-tolerant I/O only; tPD = 6.2ns max at 3.3V; smaller 14-pin TSSOP (3.5mm wide) | Lower drive strength (±4mA vs. ±24mA); no 3.6V tolerance - requires external clamping for 3.6V interfaces | Select for ultra-low static power (<1µA ICC) where speed and drive are secondary to energy efficiency |
Compared with SN74LVC00APW and 74AUP00GW, the 74VCX00MTCX uniquely supports 1.2V operation with 3.6V I/O tolerance and ±24mA drive - making it the only option among the three for 1.2V–3.6V bidirectional level translation in high-speed industrial logic interfaces.

FAQ
Is 74VCX00MTCX still in production or recommended for new designs?
No - the 74VCX00MTCX is officially discontinued and not recommended for new designs per onsemi documentation. However, Aetrix Electronics maintains active inventory and offers lifecycle support including last-time-buy planning, cross-reference guidance, and obsolescence mitigation strategies for legacy systems relying on the 74VCX00MTCX.
What is the maximum input voltage the 74VCX00MTCX can tolerate when VCC = 1.2V?
The 74VCX00MTCX supports DC input voltages up to 3.6V regardless of VCC level, including at 1.2V operation. This 3.6V tolerance is explicitly guaranteed in the Absolute Maximum Ratings table and confirmed in the Recommended Operating Conditions section of the datasheet for the 74VCX00MTCX.
Does the 74VCX00MTCX have built-in ESD protection, and what level is specified?
Yes - the 74VCX00MTCX includes on-die ESD protection rated to >2000V per Human Body Model (HBM) and >250V per Machine Model (MM), as documented in the Features section and Electrical Characteristics tables of the official 74VCX00MTCX datasheet.
Can unused inputs on the 74VCX00MTCX be left floating?
No - unused inputs on the 74VCX00MTCX must be tied HIGH or LOW per the Recommended Operating Conditions note. Floating inputs may cause increased ICC, erratic output states, or excessive power consumption due to undefined internal node biasing in the CMOS structure of the 74VCX00MTCX.
What is the thermal pad (DAP) connection requirement for the 74VCX00MTCX TSSOP package?
The die attach pad (DAP) on the 74VCX00MTCX TSSOP package is marked "No Connect" in the Pin Description table and must remain electrically unconnected - neither tied to GND nor VCC. It serves only mechanical die attachment and has no electrical function in the 74VCX00MTCX.
