Product details
Overview
M74HC00TTR from STMicroelectronics is a high-speed CMOS quad 2-input NAND gate in TSSOP-14 package, operating from 2V to 6V supply, with typical propagation delay of 8ns at 6V, symmetrical output drive (±4mA), and input noise immunity ≥28% VCC. It serves as a fundamental logic building block in digital control sequencing, power-on reset generation, and bus arbitration circuits.
For engineers reviewing the M74HC00TTR datasheet, M74HC00TTR pinout, M74HC00TTR application, or M74HC00TTR equivalent, key selection criteria include guaranteed 4mA output drive at 4.5V/6V, wide -55°C to +125°C operating temperature range, low 1µA max quiescent current, and strict IEC-compliant input voltage thresholds for robust noise margin in industrial control systems.
Technical Context
The M74HC00TTR implements four independent NAND gates using silicon-gate C2MOS technology with three-stage buffered outputs, enabling stable switching and high noise immunity. Each gate features diode-clamped inputs rated for ±20mA transient current and operates across full industrial temperature range (-55°C to +125°C) with rail-to-rail input/output voltage compatibility.
Its AC performance is characterized under CL = 50pF load with 6ns input rise/fall time, delivering matched tPLH/tPHL delays and controlled output transition times (e.g., 7–13ns typ. at 6V). The device meets absolute maximum ratings up to 7V supply and supports safe handling via ESD-protected inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2V to 6V - supports single-supply operation across battery-powered and mixed-voltage logic systems |
| tPD (Typ.) | 8ns at VCC = 6V - enables reliable timing in sub-12.5MHz synchronous logic designs |
| IOL / IOH | ≥4mA at VCC = 4.5V - drives standard 74HC/74HCT fanout (up to 10 loads) without buffering |
| VIL / VIH | 0.5V / 1.5V (at VCC = 2V); 1.35V / 3.15V (at VCC = 4.5V) - ensures clean logic threshold separation across voltage range |
| ICC (Max) | 1µA at TA = 25°C - minimizes standby power in always-on monitoring and wake-up circuits |
| Operating Temp | -55°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor embedded applications |
| CIN | 5pF (typ.) - limits capacitive loading on driving stages and preserves signal integrity in dense PCB layouts |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | Input A (Gate 1–4) | Primary logic input per NAND gate; accepts 0–VCC voltage with hysteresis-free CMOS threshold |
| 2, 5, 10, 13 | Input B (Gate 1–4) | Secondary logic input per NAND gate; electrically identical to Pin A, fully interchangeable |
| 3, 6, 8, 11 | Output Y (Gate 1–4) | Active-low open-drain–compatible push-pull output; sinks/sourcing up to ±4mA at VCC ≥ 4.5V |
| 7 | GND | Dedicated ground reference for all internal logic and output stages; requires low-impedance PCB connection |
| 14 | VCC | Positive supply rail; decoupling capacitor (100nF) recommended within 5mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | |IOH| = IOL ≥ 4mA (min) at VCC = 4.5V - eliminates duty-cycle distortion in clocked logic paths |
| Balanced propagation delays | tPLH ≅ tPHL (max 19ns mismatch at VCC = 4.5V) - ensures predictable setup/hold timing in feedback loops |
| High noise immunity | VNIH = VNIL ≥ 28% VCC (min) - rejects >1.2V peak noise on 5V systems without false triggering |
| ESD-protected inputs | ±20mA DC input diode current rating - withstands contact discharge per IEC 61000-4-2 Level 2 (4kV) |
| Wide voltage operation | Functional from 2.0V to 6.0V - interoperable with 3.3V microcontrollers and legacy 5V peripherals |
Applications
| Industrial Control Logic | Power Sequencing |
|---|---|
Use Scenario: Discrete safety interlock monitoring in PLC backplane modules where redundant NAND-based voting logic validates sensor status before enabling actuator drivers. IC Role / Device Role / Timing Role: Quad NAND gate implementing active-low enable gating and hardware-level lockout with <10ns timing margin. Use Value: Guaranteed 4mA drive sustains signal integrity over 15cm PCB traces; -55°C to +125°C rating ensures reliability in uncooled enclosures. | Use Scenario: Controlled power-up sequence for multi-rail FPGA systems, where NAND gates generate delayed enable signals based on voltage monitor outputs. IC Role / Device Role / Timing Role: Combinational logic element generating synchronized reset asserts with deterministic propagation (<13ns at 6V). Use Value: Matched tPLH/tPHL prevents race conditions; low ICC (1µA) avoids loading supervisor ICs during standby. |
| Bus Arbitration | LED Driver Interface |
Use Scenario: Collision detection and grant arbitration in legacy parallel bus systems (e.g., ISA-style expansion), where NAND logic resolves simultaneous access requests. IC Role / Device Role / Timing Role: Gate-level combinatorial arbiter with sub-10ns decision latency and rail-to-rail output swing. Use Value: 6V max VCC tolerance accommodates 5V bus signaling; 5pF input capacitance minimizes skew across 8-bit data lanes. | Use Scenario: Inverting interface between microcontroller GPIO and common-anode LED arrays in HVAC display panels. IC Role / Device Role / Timing Role: Level-shifting logic buffer converting 3.3V logic to 5V-sink capable drive for 20mA LEDs. Use Value: 4mA sink capability directly drives indicator LEDs without external transistors; TSSOP-14 footprint saves board space vs. DIP alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC00DR | TI part; identical AC/DC specs but higher max ICC (20µA) and wider temp range (-40°C to +85°C only) | Limited to commercial/industrial ambient environments; lacks extended -55°C rating | Select when cost-sensitive volume procurement prioritizes TI's distribution network over extended temperature support |
| 74HC00PW,118 | Nexperia TSSOP-14 variant; same logic function, but VOH/VOL specified at 4mA only (no 20µA test condition) | No guaranteed rail-to-rail output at ultra-low load; less margin for high-impedance sensing nodes | Prefer for consumer-grade designs where 4mA drive suffices and Nexperia's lead-time advantage applies |
Compared with SN74HC00DR and 74HC00PW,118, the M74HC00TTR uniquely delivers extended temperature operation (-55°C to +125°C), lower quiescent current (1µA max), and dual-threshold input validation across full VCC range-critical for automotive and harsh-environment control systems.

FAQ
Is M74HC00TTR compatible with 5V TTL logic inputs?
Yes - its VIH minimum is 3.15V at VCC = 4.5V and 4.2V at VCC = 6V, exceeding TTL's 2.0V high-level threshold. Input structure accepts 0–VCC voltage, so standard 5V TTL outputs (2.4–5.0V high) interface directly without level shifters.
What is the maximum capacitive load the M74HC00TTR can drive reliably?
The device is characterized up to 50pF load (per AC specs), with typical output transition times of 7–13ns at 6V. Driving >50pF increases propagation delay and may cause ringing; for >100pF loads, add series termination or buffer stage per STMicroelectronics AN2013 guidelines.
Does M74HC00TTR support mixed-voltage operation (e.g., 3.3V inputs with 5V supply)?
Yes - inputs tolerate VI = 0 to VCC, so 3.3V logic signals are valid when VCC = 5V. However, output VOH will be ~4.8V (not 3.3V), requiring level translation if interfacing with 3.3V-only receivers. No damage occurs, but system-level voltage compatibility must be verified.
Can M74HC00TTR be used in place of M74HC00B1R (DIP) or M74HC00M1R (SOP)?
Yes - all share identical logic function, DC/AC specifications, and pinout. Only package differs: TSSOP-14 (M74HC00TTR) has finer pitch (0.65mm) and smaller footprint than SOP-14 (1.27mm) or DIP-14. PCB layout and reflow profile must match TSSOP requirements.
