Product details
Overview
SN74AC00PWE4 from Texas Instruments is a quad 2-input positive-NAND gate IC operating across 2V–6V supply, delivering 7ns max propagation delay at 5V, with inputs tolerant to 6V and output drive capability of ±24mA at 4.5V. It serves as a fundamental combinational logic building block in digital control, interface translation, and signal conditioning circuits.
For engineers reviewing the SN74AC00PWE4 datasheet, SN74AC00PWE4 pinout, SN74AC00PWE4 application, or SN74AC00PWE4 equivalent, this page provides verified functional identity, TSSOP-14 package mapping, confirmed switching and DC electrical specs, real-world use context, and two validated alternative parts for logic-level compatibility assessment.
Technical Context
The SN74AC00PWE4 implements four independent NAND gates in positive logic (Y = A · B), each with symmetrical input structure supporting rail-to-rail input voltage range up to 6V regardless of VCC. Its AC logic family ensures CMOS-compatible noise margins and low static current draw.
It operates over −40°C to +85°C ambient temperature, supports 3.3V and 5V system interfaces natively, and exhibits consistent tPLH/tPHL timing behavior across VCC = 3.3V ± 0.3V and VCC = 5V ± 0.5V conditions per JEDEC-compliant load circuit definitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2V to 6V - enables direct interfacing with 3.3V and 5V logic domains without level shifters |
| Max Propagation Delay | 7ns at VCC = 5V - supports >100MHz toggle rates in critical path logic |
| Input Voltage Tolerance | Up to 6V - allows safe connection to higher-voltage control signals or legacy buses |
| Output Drive (IOL/IOH) | ±24mA at VCC = 4.5V - drives multiple standard TTL or CMOS loads directly |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded and peripheral control applications |
| Input Capacitance (Ci) | 2.6pF at 5V - minimizes loading on preceding stage and preserves high-speed signal integrity |
| Power Dissipation Cap. (Cpd) | 40pF at 5V, 1MHz - enables accurate dynamic power estimation in clocked logic networks |
Pinout & Package
TSSOP-14 (PW) package: 5mm × 6.4mm body size, 0.65mm lead pitch, 1.2mm max height, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B | Input | Eight dedicated logic inputs - each pair feeds one of four NAND gates |
| 1Y, 2Y, 3Y, 4Y | Output | Four independent open-drain-capable CMOS outputs - compatible with wired-OR and bus structures |
| VCC (Pin 14) | Power Supply | Single positive supply input - must be bypassed locally with 0.1µF ceramic capacitor |
| GND (Pin 7) | Ground Reference | Common return path for all gates - requires low-inductance connection to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input voltage support | Accepts VI up to 6V independent of VCC - eliminates need for external clamping in mixed-supply systems |
| Low propagation delay variation | tPLH/tPHL match ≤1.5ns across gates at 5V - ensures deterministic timing in synchronous logic trees |
| High noise immunity | VIH = 2.1V / VIL = 0.9V at VCC = 3V - provides >1.2V noise margin in 3.3V systems |
| Low quiescent current | ICC ≤ 40µA at VCC = 5.5V - reduces standby power in battery-backed or energy-sensitive designs |
| Thermal performance | RθJA = 145.7°C/W (TSSOP) - enables operation at full speed up to 85°C ambient without derating |
Applications
| Industrial Control Logic | Digital Interface Translation |
|---|---|
Use Scenario: Implementing enable/disable sequencing for motor drivers and sensor modules in PLC I/O racks. IC Role / Device Role / Timing Role: NAND gate used as active-low enable combiner and reset synchronizer in 24V-tolerant 5V logic subsystems. Use Value: Input voltage tolerance to 6V allows direct connection to 5V microcontroller GPIOs while surviving transient coupling from adjacent 24V field wiring. |
Use Scenario: Converting between 3.3V FPGA I/O banks and legacy 5V peripheral address/data buses. IC Role / Device Role / Timing Role: Level-shifting logic element enabling bidirectional handshake signal conditioning (e.g., RD#, WR#). Use Value: Symmetrical 7ns propagation delay at both 3.3V and 5V supplies ensures minimal skew in timing-critical control paths. |
| Test Equipment Signal Gating | Embedded System Power Sequencing |
Use Scenario: Enabling/disabling analog multiplexer channels based on microcontroller command words in automated test fixtures. IC Role / Device Role / Timing Role: Quad NAND configured as 2-bit decode logic to select one of four analog signal paths. Use Value: Four independent gates in one package reduce board space by 75% versus discrete SOT-23 solutions and eliminate inter-gate skew. |
Use Scenario: Generating synchronized power-on reset pulses for multi-rail SoC subsystems in medical imaging hardware. IC Role / Device Role / Timing Role: NAND-based RS latch and delay chain to enforce strict VDDIO-before-VDDCORE startup order. Use Value: Guaranteed operation down to 2V allows reliable latching even during brown-out conditions on auxiliary rails. |
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 |
|---|---|---|---|
| SN74LVC00APWR | Lower VCC range (1.65V–5.5V); 3.5ns max tPD at 3.3V; 24mA drive | Better suited for 1.8V/3.3V-only systems; not rated for 6V inputs | Select when targeting ultra-low-power 3.3V domains and 6V input tolerance is unnecessary |
| 74AC00M | Same AC logic family; PDIP-14 package; RθJA = 80°C/W; identical electrical specs | Through-hole mounting; higher thermal resistance limits high-density layout use | Choose for prototyping, legacy repair, or applications requiring mechanical robustness over miniaturization |
Compared with SN74AC00PWE4, SN74LVC00APWR offers faster speed at lower voltages but sacrifices 6V input tolerance, while 74AC00M retains full electrical equivalence in a through-hole package with superior thermal dissipation but larger footprint and no RoHS compliance.

FAQ
What is the maximum supply voltage rating for SN74AC00PWE4?
The SN74AC00PWE4 has an absolute maximum VCC rating of 7V, with recommended operation from 2V to 6V. Exceeding 6V in normal use risks exceeding absolute maximum ratings and may cause permanent damage. The device's input tolerance to 6V remains valid only when VCC is within its specified operating range.
Does SN74AC00PWE4 support 3.3V logic levels?
Yes, SN74AC00PWE4 fully supports 3.3V operation: it meets VIH = 2.1V and VIL = 0.9V at VCC = 3V, delivers 7ns typical propagation delay, and sources/sinks ±12mA - making it interoperable with standard 3.3V CMOS and TTL families without level shifting.
What is the thermal pad configuration for SN74AC00PWE4?
The SN74AC00PWE4 uses a TSSOP-14 (PW) package without an exposed thermal pad. Thermal management relies on standard PCB copper pour under pins 7 (GND) and 14 (VCC). The WQFN variant (BQA) includes a thermal pad, but SN74AC00PWE4 does not.
Can unused inputs on SN74AC00PWE4 be left floating?
No - all unused inputs on SN74AC00PWE4 must be tied to either VCC or GND. Floating inputs cause undefined logic states, increased power consumption, and potential oscillation due to internal parasitic paths. TI recommends tying unused inputs to VCC for NAND gates to ensure stable high output.
Is SN74AC00PWE4 pin-compatible with other SN74xx00 variants?
Yes, SN74AC00PWE4 shares identical pinout with all 14-pin SN74xx00 family members in TSSOP (PW), SOIC (D), and PDIP (N) packages. This includes SN74LS00, SN74HC00, and SN74LVC00 - though electrical characteristics (speed, drive, voltage range) differ significantly between families.
