Product details
Overview
74HC240PW-Q100 from Nexperia is an automotive-qualified octal inverting 3-state buffer/line driver in TSSOP20 package, operating from 2.0 V to 6.0 V supply, delivering 11 ns typical propagation delay at 4.5 V, ±35 mA output drive, and qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C) for engine control and body electronics applications.
For engineers reviewing the 74HC240PW-Q100 datasheet, 74HC240PW-Q100 pinout, 74HC240PW-Q100 application, or 74HC240PW-Q100 equivalent, this page provides verified functional identity, validated pin roles, confirmed automotive temperature and voltage specs, and real-world interface use cases - all derived from Nexperia's official Rev. 3 product data sheet dated 5 August 2024.
Technical Context
This device implements two independent 4-bit inverting buffers, each with dedicated active-low 3-state enable (1OE, 2OE), enabling bidirectional bus isolation in automotive domain controllers. Its CMOS architecture ensures high noise immunity (≥40 % of VCC), latch-up immunity >100 mA, and compatibility with LSTTL logic levels when operated at 4.5–5.5 V (74HCT variant behavior).
It supports dual-rail operation across 2.0–6.0 V, with VIH/VIL thresholds scaling with VCC for HC logic, while maintaining consistent 3-state timing (ten/tdis ≤30 ns at 4.5 V) and low dynamic power via 30 pF CPD per buffer - critical for low-EMI CAN/LIN subsystem interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Octal inverting buffer with dual 3-state enables (1OE, 2OE); outputs go high-Z when enable is HIGH. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports wide-input automotive battery rails including cold-crank (≈6.0 V) and deep-sleep (≈2.0 V) conditions. |
| Propagation Delay (tpd) | 11 ns typ. @ VCC = 4.5 V, CL = 15 pF - enables reliable timing in 20+ MHz digital bus interfaces. |
| Output Drive | ±35 mA per output - sufficient to directly drive LED indicators, relay coils, or terminated transmission lines without external amplification. |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1, validated for under-hood ECU and ADAS sensor hub deployment. |
| Input Capacitance (CI) | 3.5 pF - minimizes capacitive loading on upstream MCU GPIOs or clock distribution nets. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive board-level robustness requirements without added protection circuitry. |
Pinout & Package
TSSOP20 package (SOT360-1): plastic thin shrink small outline, 20 leads, 4.4 mm body width, 0.65 mm pitch, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low 3-state enable inputs - tie LOW to activate respective 4-bit buffer bank; tie HIGH to isolate bus. |
| 2, 4, 6, 8 | 1A0–1A3 | First bank input signals - inverted and driven to 1Y0–1Y3 outputs when 1OE = LOW. |
| 18, 16, 14, 12 | 1Y0–1Y3 | First bank inverting outputs - high-Z when 1OE = HIGH; logic-complementary to 1A0–1A3 when enabled. |
| 17, 15, 13, 11 | 2A0–2A3 | Second bank input signals - inverted and driven to 2Y0–2Y3 outputs when 2OE = LOW. |
| 3, 5, 7, 9 | 2Y0–2Y3 | Second bank inverting outputs - high-Z when 2OE = HIGH; logic-complementary to 2A0–2A3 when enabled. |
| 10 | GND | Ground reference (0 V) - must be connected to system ground plane for stable noise margin and thermal dissipation. |
| 20 | VCC | Positive supply rail - decoupling capacitor (100 nF ceramic) required within 5 mm for transient current stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with full parametric testing - eliminates need for customer requalification in automotive ECUs. |
| Dual independent 3-state control | Separate 1OE and 2OE pins allow selective isolation of two 4-bit data paths - essential for multiplexed sensor readout or dual-CAN transceiver buffering. |
| Wide VCC range (2.0–6.0 V) | Enables direct interface with 3.3 V MCUs, 5 V legacy peripherals, and 12 V battery-supplied systems via LDO - no level-shifting required. |
| Low dynamic power (CPD = 30 pF) | Reduces switching current demand and heat generation in densely packed modules - supports >100 kHz continuous toggle without thermal derating. |
| Side-wettable flanks (TSSOP20) | Enables automated optical inspection (AOI) of solder joints - improves manufacturing yield and field-reliability traceability in Tier-1 production. |
Applications
| Engine Control Unit (ECU) I/O Expansion | Body Control Module (BCM) Signal Multiplexing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT240PW-Q100 | CMOS/TTL-compatible input thresholds (VIH = 2.0 V min), optimized for 4.5–5.5 V systems; identical pinout and timing. | Better suited for mixed-voltage boards with legacy 5 V logic; slightly higher ICC at 5.5 V (160 μA vs. 80 μA for HC). | Select when interfacing with standard TTL or 5 V microcontrollers where input threshold compatibility is critical. |
| SN74LVC240APWR | Lower VCC range (1.65–3.6 V), 32 mA drive, 3.5 ns tpd at 3.3 V; non-automotive grade (−40 °C to +125 °C not AEC-Q100 qualified). | Targeted at consumer-grade infotainment submodules; lacks automotive stress testing and failure-rate reporting. | Use only in non-safety-critical cabin modules where AEC-Q100 compliance is not mandated by OEM specification. |
Compared with 74HCT240PW-Q100, the 74HC240PW-Q100 offers lower static current and wider VCC flexibility but requires level-aware design; versus SN74LVC240APWR, it trades speed for automotive qualification and broader voltage tolerance - making it the sole choice for under-hood and safety-related domains.

FAQ
Is the 74HC240PW-Q100 pin-compatible with standard 74HC240 devices?
Yes - the 74HC240PW-Q100 shares identical pinout, logic function, and electrical characteristics with industrial-grade 74HC240 in TSSOP20 (SOT360-1), but adds AEC-Q100 Grade 1 qualification, extended temperature validation (−40 °C to +125 °C), and automotive-specific reliability testing per JESD22-A108 and A114 standards.
What is the maximum output current per pin, and can it drive LEDs directly?
The absolute maximum output current is ±35 mA per pin, and yes - it can drive standard 20 mA LEDs directly in sink configuration (anode to VCC, cathode to Yn). At 5 V supply and 20 mA load, VOL remains ≤0.26 V, ensuring ≥4.74 V forward bias for red/green/yellow LEDs without external current-limiting resistors.
How does the 3-state enable logic work, and what happens if OE is left floating?
1OE and 2OE are active-low enables: a LOW activates the corresponding 4-bit buffer bank; a HIGH forces outputs to high-impedance. If left floating, internal pull-downs (typ. 100 kΩ) ensure default HIGH state - placing outputs in high-Z. However, best practice mandates explicit LOW/HIGH termination to prevent noise-induced glitches during power-up.
Does this device support hot-swap or live-insertion in backplane applications?
No - the 74HC240PW-Q100 lacks powered-off protection (Ioff) and bus-hold features. During hot-swap, unpowered VCC creates undefined internal node states, risking latch-up or excessive current draw. For live-insertion, use devices with Ioff specification (e.g., 74LVC240A) or add external series resistors and power sequencing controls.
