Product details

Overview

74AHCT00D/S400,118 from Nexperia is a quad 2-input NAND gate IC with TTL-compatible input thresholds, 4.5 V to 5.5 V supply operation, overvoltage-tolerant inputs up to 5.5 V, and SO14 (SOT108-1) package. It functions as a level-translating logic gate in mixed-voltage digital systems, enabling interface between 3.3 V and 5 V domains in industrial control I/O modules.

For engineers reviewing the 74AHCT00D/S400,118 datasheet, 74AHCT00D/S400,118 pinout, 74AHCT00D/S400,118 application, or 74AHCT00D/S400,118 equivalent, key selection criteria include TTL-level input compatibility, propagation delay ≤9.0 ns at 5 V/50 pF, SO14 thermal derating above 100 °C, and guaranteed operation from −40 °C to +125 °C.

Technical Context

This device implements four independent NAND gates with Schmitt-trigger inputs for noise immunity and balanced HIGH/LOW propagation delays. Its TTL input threshold (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensures direct compatibility with legacy 5 V TTL outputs without pull-up resistors.

The overvoltage-tolerant inputs (rated to 5.5 V regardless of VCC) allow safe interfacing with higher-voltage signals in mixed-supply systems, while the CMOS output stage delivers rail-to-rail swing and ±8 mA drive capability at 5 V - supporting fan-out to multiple 74-series loads.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input NAND gate - four independent gates per package, each implementing Y = NOT(A AND B)
Supply Voltage Range	4.5 V to 5.5 V - operates reliably across full industrial 5 V rail tolerance, including noisy or underspecified power supplies
Input Threshold Type	TTL-compatible - VIH ≥ 2.0 V, VIL ≤ 0.8 V enables direct connection to standard 5 V TTL outputs without level shifters
Propagation Delay	≤9.0 ns (max) at VCC = 5 V, CL = 50 pF - supports >50 MHz toggle rates in synchronous logic paths
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive auxiliary modules and industrial motor drives
Input Overvoltage Tolerance	5.5 V absolute max on any input - permits safe use in mixed-voltage backplanes where 3.3 V logic interfaces with 5 V control lines
ESD Protection	HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events in automated assembly environments

Pinout & Package

74AHCT00D/S400,118 is housed in a plastic small outline package (SO14), SOT108-1, with 14 leads and 3.9 mm body width. Pin 1 is marked by a notch or dot; the package is lead-free and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1A, 2A, 3A, 4A (Pins 1, 4, 9, 12)	Data Input A	First input of each NAND gate; accepts TTL- or CMOS-level signals up to 5.5 V
1B, 2B, 3B, 4B (Pins 2, 5, 10, 13)	Data Input B	Second input of each NAND gate; identical electrical characteristics to A inputs
1Y, 2Y, 3Y, 4Y (Pins 3, 6, 8, 11)	Data Output	Active-low NAND output; drives CMOS/TTL loads with VOH ≥ 3.7 V and VOL ≤ 0.55 V at 8 mA
GND (Pin 7)	Ground Reference	0 V return path for all internal circuitry and output current sinks
VCC (Pin 14)	Supply Voltage	Primary power rail; must be decoupled locally with ≥100 nF ceramic capacitor

Key Features

Feature	Design Value
TTL-compatible input levels	Enables plug-in replacement of legacy 74LS00 in 5 V systems without redesigning input biasing networks
Overvoltage-tolerant inputs	Eliminates need for external clamping diodes when interfacing with 5 V signals in 3.3 V domains
Balanced propagation delays	Ensures predictable timing margins in combinational logic chains - tPLH ≈ tPHL within 0.5 ns
Schmitt-trigger inputs	Provides 0.4 V typical hysteresis, rejecting noise spikes <100 ns wide on slow-rising control lines
Wide temperature range	Validated operation from −40 °C to +125 °C supports deployment in unheated outdoor enclosures and engine bay proximity

Applications

Industrial PLC I/O Expansion

Legacy System Bus Interface

Use Scenario: Adding isolated digital input channels to a 5 V PLC base unit using optocoupler-based signal conditioning.

IC Role / Device Role / Timing Role: NAND gate used as active-low enable controller for address decoding and strobe generation in parallel I/O expansion cards.

Use Value: TTL input compatibility allows direct connection to microcontroller port pins without level-shifting; overvoltage tolerance protects against transient coupling from adjacent 24 V field wiring.

Use Scenario: Interfacing a modern ARM-based controller (3.3 V GPIO) to an aging 5 V ISA bus peripheral card.

IC Role / Device Role / Timing Role: Level-translating logic gate converting 3.3 V control signals to 5 V-compatible enable/strobe lines while preserving setup/hold timing.

Use Value: Input overvoltage tolerance eliminates risk of damage during hot-plug events; 9 ns max delay ensures timing compliance with ISA bus 8 MHz clock domain.

Automotive Body Control Module

Test Equipment Signal Conditioning

Use Scenario: Implementing window lockout logic and door latch status arbitration in a BCM operating at 5 V with extended temperature requirements.

IC Role / Device Role / Timing Role: Combinational logic element generating safety interlock signals from multiple sensor inputs (door open, ignition state, child lock).

Use Value: −40 °C to +125 °C qualification matches under-dash ambient conditions; low ICC (<40 μA at 5.5 V) minimizes quiescent current draw in always-on subsystems.

Use Scenario: Building a programmable logic adapter for benchtop test fixtures that route trigger signals between 3.3 V FPGA logic analyzers and 5 V DUTs.

IC Role / Device Role / Timing Role: Glue logic gate synchronizing asynchronous control pulses and debouncing mechanical switch inputs before routing to measurement hardware.

Use Value: Schmitt-trigger inputs suppress contact bounce on manual test switches; SO14 package allows hand-soldering and socket-based reconfiguration during fixture development.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74AHC00D,118	CMOS input thresholds (VIH = 3.85 V @ 5.5 V); lower ICC but incompatible with TTL outputs	Requires pull-up resistors or voltage translation when driven by 5 V TTL sources	Select only when driving exclusively from CMOS or 3.3 V logic; not drop-in for 74LS/74F legacy systems
SN74LVC00APWR	3.3 V only supply (1.65–3.6 V); LVTTL-compatible inputs; smaller TSSOP-14 footprint	Cannot operate at 5 V; unsuitable for direct 5 V bus interfacing without external level shifters	Preferred for new 3.3 V-only designs where board space is constrained and 5 V compatibility is unnecessary

Compared with 74AHCT00D/S400,118, the 74AHC00D,118 lacks TTL input compatibility but offers lower static power and wider VCC range, while SN74LVC00APWR reduces size and cost in 3.3 V systems but forfeits 5 V operation and mixed-voltage robustness.

FAQ

Is 74AHCT00D/S400,118 pin-compatible with 74LS00?

Yes - it uses the same SO14 pinout as standard 74LS00, with identical pin assignments for inputs (1A–4B), outputs (1Y–4Y), GND (Pin 7), and VCC (Pin 14). Electrical compatibility is ensured by TTL-level input thresholds and output drive strength matching 74LS series specifications.

Can 74AHCT00D/S400,118 operate at 3.3 V supply?

No - the 74AHCT variant is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds become undefined and output drive falls outside guaranteed specs. For 3.3 V systems, use the 74AHC00D or 74LVC00 variants instead.

What is the maximum capacitive load this device can drive reliably?

The datasheet specifies timing parameters up to 50 pF load capacitance. Driving >50 pF may increase propagation delay beyond 9.0 ns and cause marginal timing in high-speed paths; for heavier loads, add a buffer stage or reduce trace length and stubs to minimize parasitic capacitance.

Does the SO14 package require thermal vias or special PCB layout?

For continuous operation at +125 °C ambient, the SO14 package (SOT108-1) requires Ptot derating above 100 °C at 10.1 mW/K. Use at least two 0.3 mm thermal vias under the exposed pad (if present) or adjacent copper pour to maintain junction temperature below 150 °C under worst-case load conditions.
