Product details
Overview
74VHC00MTC from Fairchild Semiconductor is a quad 2-input NAND gate in a 14-lead TSSOP package, operating across 2.0V–5.5V supply, delivering 3.7ns typical propagation delay at 5V, ±8mA output drive, and 2µA max quiescent current - used for logic-level translation and signal conditioning in mixed-voltage digital systems.
For engineers reviewing the 74VHC00MTC datasheet, pinout, applications, or equivalent options, key selection factors include its 5.5V absolute input tolerance, power-down input protection, low dynamic noise (VOLP ≤ 0.8V), and compatibility with 3.3V/5V interface domains.
Technical Context
The 74VHC00MTC implements four independent CMOS NAND gates using silicon-gate VHC technology, with three-stage buffered outputs to ensure high noise immunity (VNIH/VNIL ≥ 28% VCC) and stable switching. Input protection allows safe operation with inputs up to 7V regardless of VCC.
It supports dual-supply system interfacing (e.g., 5V logic driving 3V loads) and battery-backup circuits due to rail-to-rail input voltage tolerance (–0.5V to +7.0V) and guaranteed operation from –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND - enables compact implementation of combinational logic, inverters (via tied inputs), and basic control gating. |
| Propagation Delay | 3.7ns typical at VCC = 5.0V, CL = 15pF - ensures timing-critical path compatibility with 74HC and TTL-equivalent systems. |
| Supply Voltage Range | 2.0V to 5.5V - supports single-supply operation across 3.3V and 5V domains without level shifters. |
| Output Drive | ±8mA at VCC = 4.5V - sufficient to drive multiple 74VHC inputs or small capacitive loads (<50pF) directly. |
| Input Voltage Tolerance | –0.5V to +7.0V - enables robust interfacing between mismatched supplies and prevents damage during hot-insertion or brown-out. |
| Quiescent ICC | 2µA maximum at TA = 25°C - minimizes standby power in battery-powered or always-on logic subsystems. |
Pinout & Package
74VHC00MTC is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 4.4mm wide, with 0.65mm lead pitch and exposed pad not present. Pin 1 marked by beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | Inputs (A1/B1, A2/B2, A3/B3, A4/B4) | Four independent NAND gate inputs; each pair accepts DC voltages up to 7V independent of VCC. |
| 3, 6, 10, 11 | Outputs (Y1–Y4) | CMOS push-pull outputs capable of sourcing/sinking ±8mA; VOL ≤ 0.44V at IOL = 8mA (VCC = 4.5V). |
| 7 | GND | Ground reference for all logic and power paths; must be low-impedance for noise control. |
| 14 | VCC | Positive supply rail (2.0–5.5V); decoupling capacitor (0.1µF) required near this pin for AC stability. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed CMOS architecture | 3.7ns tPD at 5V enables replacement of 74LS/74F logic without increasing system power. |
| Input overvoltage tolerance | Inputs withstand –0.5V to +7.0V regardless of VCC - eliminates need for external clamping in mixed-supply designs. |
| Power-down input protection | All inputs remain protected when VCC = 0V - prevents back-powering or latch-up during power sequencing. |
| Low dynamic output noise | VOLP ≤ 0.8V (CL = 50pF) reduces ground bounce and crosstalk in dense PCB layouts. |
| PIN- and function-compatible with 74HC00 | Direct drop-in replacement for legacy 74HC00 designs with improved speed and noise margin. |
Applications
| Industrial Control Logic | 3.3V/5V Level Translation |
|---|---|
Use Scenario: Interlocking safety circuits in PLC I/O modules requiring fast, reliable NAND-based enable/disable gating. IC Role / Device Role / Timing Role: Quad NAND gate implementing hardware interlock logic with sub-10ns response to fault signals. Use Value: 2.0–5.5V operation and ±8mA drive allow direct connection to relay drivers and optocouplers without buffers. |
Use Scenario: Bidirectional voltage translation between 5V microcontroller GPIO and 3.3V sensor interface lines. IC Role / Device Role / Timing Role: Logic-level translator using NAND configuration (input tied HIGH) to invert and shift signals. Use Value: 7V-tolerant inputs accept 5V signals safely while output swings rail-to-rail at 3.3V, eliminating external resistors. |
| Battery-Backed Memory Interface | Digital Power Sequencing |
Use Scenario: Enabling write-protection logic for SRAM or EEPROM in systems with main + backup (coin-cell) power rails. IC Role / Device Role / Timing Role: NAND gate combining main-VCC status and write-enable signals to gate memory writes during brown-out. Use Value: Input protection and 0V–7V tolerance prevent corruption when backup supply powers inputs before main VCC rises. |
Use Scenario: Generating synchronized enable signals for multiple DC-DC converters in FPGA or ASIC power trees. IC Role / Device Role / Timing Role: NAND-based combinatorial logic generating delayed or conditional enable pulses from reset and clock signals. Use Value: 3.7ns propagation delay ensures tight timing alignment across power rails; low ICC minimizes idle current draw. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74VHC00DR | TSSOP-14 package, identical electrical specs, TI-branded; same 3.7ns tPD and 2µA ICC, but different thermal resistance (θJA = 133°C/W vs Fairchild's 120°C/W). | Qualified for automotive AEC-Q100 Grade 1 (–40°C to +125°C), whereas 74VHC00MTC is rated only to +85°C. | Select SN74VHC00DR for extended temperature or automotive use; otherwise, 74VHC00MTC offers identical logic performance at lower cost. |
| 74HC00PW,118 | Same TSSOP-14 footprint, but slower (tPD = 7ns @ 5V), higher ICC (4µA max), and narrower VCC range (2.0–6.0V). | Lacks 7V input tolerance - inputs limited to 0–VCC, requiring external clamping when interfacing >VCC signals. | Choose 74HC00PW,118 only if legacy 74HC timing margins are acceptable and input voltage matching is guaranteed. |
Compared with SN74VHC00DR and 74HC00PW,118, the 74VHC00MTC delivers superior speed and input ruggedness within industrial temperature limits, making it optimal for cost-sensitive, mixed-voltage digital control where 7V-tolerant inputs and <4ns delay are critical.

FAQ
What is the maximum input voltage rating for the 74VHC00MTC?
The 74VHC00MTC supports DC input voltages from –0.5V to +7.0V, independent of VCC level. This allows safe interfacing with higher-voltage signals (e.g., 5V outputs into a 3.3V system) without external clamping diodes or level shifters, a key advantage over standard 74HC devices limited to 0–VCC.
Is the 74VHC00MTC pin-compatible with the 74HC00 series?
Yes, the 74VHC00MTC is pin- and function-compatible with the 74HC00 family. It uses the same 14-pin TSSOP layout and truth table, enabling direct replacement in existing designs - with added benefits including faster propagation delay (3.7ns vs ~7ns), lower ICC, and enhanced input voltage tolerance.
What is the recommended operating temperature range for the 74VHC00MTC?
The 74VHC00MTC is specified for operation from –40°C to +85°C. This industrial-grade temperature range ensures reliable performance in factory automation, networking equipment, and outdoor electronics where ambient conditions exceed commercial limits.
Does the 74VHC00MTC require external pull-up or pull-down resistors on unused inputs?
Yes - per datasheet guidance, all unused inputs on the 74VHC00MTC must be terminated to either VCC or GND. Floating inputs can cause increased ICC, erratic output behavior, or localized heating due to intermediate biasing of internal CMOS stages.
Can the 74VHC00MTC be used in battery-backed systems where VCC may be 0V while inputs remain active?
Yes - the 74VHC00MTC includes power-down input protection, allowing inputs to be driven from external sources (e.g., backup battery lines) even when VCC = 0V. This prevents back-powering and ensures safe operation during power-loss transitions in memory retention or real-time clock circuits.
