Product details
Overview
74VHC00TTR from STMicroelectronics is a quad 2-input NAND gate in TSSOP-14 package, operating across 2V–5.5V supply, delivering 3.7ns typical propagation delay at 5V, ±8mA symmetrical output drive, and 2µA max quiescent current at 25°C - used in level-shifting logic interfaces between 3V and 5V systems.
For engineers reviewing the 74VHC00TTR datasheet, 74VHC00TTR pinout, 74VHC00TTR application, or 74VHC00TTR equivalent, key selection criteria include input voltage tolerance (0–7V independent of VCC), power-down input protection, ESD immunity (2kV), balanced tPLH/tPHL delays, and compatibility with legacy 74-series logic footprints.
Technical Context
The 74VHC00TTR implements four independent NAND gates using sub-micron C2MOS technology with three-stage buffered outputs, enabling high noise immunity (VNIH/VNIL ≥28% VCC) and stable switching under mixed-voltage conditions. Its inputs accept 0–7V regardless of VCC, supporting robust 5V-to-3V interfacing without external level shifters.
All inputs feature power-down protection and diode clamping; outputs provide symmetrical sourcing/sinking (≥8mA) with low dynamic noise (VOLP ≤0.8V at 5V, CL=50pF). The device meets industrial temperature range (–55°C to +125°C) and exhibits latch-up immunity per JEDEC JESD78.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 3.7ns typ. at VCC=5V, CL=15pF - enables >100MHz toggle rates in clean logic paths |
| Supply Voltage Range | 2V to 5.5V - supports single-supply operation across 3.3V and 5V systems |
| Input Voltage Range | –0.5V to +7.0V - allows hot-swap and overvoltage-tolerant inputs independent of VCC |
| Output Drive | ±8mA min. - ensures reliable fanout into standard CMOS/TTL loads without buffering |
| Quiescent Current | 2µA max. at TA=25°C - critical for battery-backed or always-on control logic |
| ESD Immunity | 2kV HBM - protects against handling damage during PCB assembly and field service |
| Operating Temperature | –55°C to +125°C - qualified for automotive under-hood and industrial motor-control environments |
Pinout & Package
TSSOP-14 package: 4.4mm × 5.0mm body, 0.65mm pitch, 1.05mm max height, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each NAND gate - accepts 0–7V, protected by clamping diodes |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each NAND gate - identical voltage tolerance and protection as A inputs |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Active-low NAND output - drives loads up to ±8mA with rail-to-rail swing |
| 7 | GND | Ground reference - decoupling capacitor required within 5mm for noise suppression |
| 14 | VCC | Positive supply - must be bypassed locally; supports 2V–5.5V with full AC/DC spec compliance |
Key Features
| Feature | Design Value |
|---|---|
| Input Overvoltage Tolerance | 0–7V on all inputs regardless of VCC - eliminates need for external clamping in mixed-rail systems |
| Symmetrical Output Drive | |IOH| = IOL ≥ 8mA - ensures matched rise/fall times and predictable timing margins |
| Power-Down Input Protection | Inputs remain high-impedance and non-disruptive when VCC = 0V - prevents backfeeding |
| Low Dynamic Noise | VOLP ≤ 0.8V at 5V, CL = 50pF - reduces crosstalk in dense logic layouts |
| Pin-Compatible Upgrade | Direct replacement for 74HC00 and 74LS00 footprints - no PCB redesign required |
Applications
| Industrial PLC I/O Modules | Automotive Body Control Units |
|---|---|
Use Scenario: Signal conditioning and enable gating for discrete sensor inputs and relay drivers in modular I/O racks. IC Role / Device Role / Timing Role: Logic-level NAND gate performing active-low enable/disable and signal inversion with deterministic propagation delay. Use Value: Wide VCC range (2–5.5V) matches varied module supply rails; 2kV ESD withstands factory handling and field maintenance. |
Use Scenario: Interfacing microcontroller GPIOs to 12V lamp drivers and door-lock actuators via optocouplers or discrete transistors. IC Role / Device Role / Timing Role: Level-shifting logic gate translating 3.3V MCU outputs to 5V-compatible control signals with overvoltage-safe inputs.

IC Role / Device Role / Timing Role: Glue logic element generating synchronized enable pulses with matched tPLH/tPHL for deterministic startup timing. Use Value: Balanced propagation delays (tPLH ≅ tPHL) eliminate skew-induced race conditions; low ICC enables energy-efficient standby modes. |
Use Scenario: Isolating and validating safety-critical control signals between microcontroller and motorized stage drivers in imaging platforms. IC Role / Device Role / Timing Role: Redundant logic gate verifying dual-channel command validity before actuator activation. Use Value: Latch-up immunity and 2kV ESD meet IEC 60601-1 requirements; quiescent current <2µA supports long-term battery backup. |
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 |
|---|---|---|---|
| 74HC00DT | Slower tPD (15ns typ. at 5V); higher ICC (4µA typ.); no 7V input tolerance | Limited to 5V-only systems; unsuitable for hot-swap or mixed-voltage interface | Select when cost is primary and performance/robustness requirements are relaxed |
| SN74LVC00APWR | Wider VCC range (1.65–5.5V); lower VOL (0.55V max. at 8mA); 3.3V-optimized | Better for 1.8V/3.3V domains; lacks 7V input tolerance and industrial temp support | Prefer for modern low-voltage designs where 7V input margin is unnecessary |
Compared with 74HC00DT and SN74LVC00APWR, the 74VHC00TTR uniquely combines 7V input tolerance, industrial temperature range, and sub-4ns speed - making it optimal for legacy-compatible, ruggedized, mixed-rail logic interfacing where reliability trumps lowest cost or lowest voltage.

FAQ
Can 74VHC00TTR operate with VCC = 2.5V?
Yes. The device is fully specified from 2V to 5.5V, including DC and AC parameters. At VCC = 2.5V, VIH = 1.75V min., VIL = 0.75V max., and tPD increases to ~9.5ns (CL = 15pF, TA = 25°C), maintaining functional correctness in low-voltage embedded systems.
Is 74VHC00TTR pin-compatible with 74LS00?
Yes - it uses the same TSSOP-14 footprint and logic function mapping as 74LS00, but with CMOS input structure (high impedance, no input current), wider voltage range, and no need for pull-up resistors. Direct replacement is electrically safe and mechanically identical.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies AC performance up to CL = 50pF. Driving >50pF increases propagation delay and may cause ringing or reduced noise margin. For loads exceeding 50pF, add a series resistor (22–47Ω) near the output to dampen reflections and maintain signal integrity.
Does 74VHC00TTR require external pull-up or pull-down resistors on unused inputs?
No. Unused inputs may be tied directly to VCC or GND. Due to CMOS input structure and internal protection, floating inputs are not permitted - they risk increased ICC and unpredictable output states. Permanent connection avoids noise susceptibility and static discharge risks.
