Product details
Overview
74HCT241PW-Q100 from Nexperia is an automotive-qualified octal non-inverting 3-state buffer/line driver with dual independent output enables (1OE active LOW, 2OE active HIGH), operating from 4.5 V to 5.5 V supply, specified over −40 °C to +125 °C, and used for bidirectional bus isolation in automotive body control modules.
For engineers reviewing the 74HCT241PW-Q100 datasheet, 74HCT241PW-Q100 pinout, 74HCT241PW-Q100 application, or 74HCT241PW-Q100 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min at VCC = 4.5 V), 3-state enable timing (ten = 30 ns max at VCC = 4.5 V), propagation delay (tpd = 22 ns max), latch-up immunity (>100 mA), and AEC-Q100 Grade 1 qualification.
Technical Context
This device implements two independent 4-bit buffered data paths: inputs 1A0–1A3 drive outputs 1Y0–1Y3 under control of 1OE (active LOW); inputs 2A0–2A3 drive outputs 2Y0–2Y3 under control of 2OE (active HIGH). Each output exhibits non-inverting logic and high-impedance OFF-state when its respective enable is inactive.
Input clamp diodes allow safe interfacing to voltages exceeding VCC using external current-limiting resistors. Reduced input threshold levels (VIH = 2.0 V, VIL = 0.8 V) ensure reliable compatibility with legacy TTL logic families across full automotive temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 4.5 V to 5.5 V - supports stable operation across automotive battery variation including cold-crank conditions. |
| Operating temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
| Propagation delay | 22 ns max (VCC = 4.5 V, CL = 15 pF) - ensures deterministic timing in high-speed bus buffering. |
| Enable/disable time | 30 ns max (ten/tdis, VCC = 4.5 V) - enables precise bus arbitration and hot-swap control. |
| Output drive | ±6 mA (VOH/VOL guaranteed) - sufficient to drive standard CMOS/TTL loads without external buffers. |
| Input threshold | VIH = 2.0 V min, VIL = 0.8 V max - guarantees interoperability with 5 V TTL logic without level-shifting. |
| ESD protection | HBM > 2000 V, CDM > 1000 V - meets automotive robustness requirements for assembly and field operation. |
Pinout & Package
TSSOP20 package (SOT360-1): 20-pin plastic thin shrink small outline, 4.4 mm body width, 0.65 mm lead pitch, surface-mount compatible with automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE (pin 1), 2OE (pin 19) | Independent 3-state enables: 1OE active LOW controls Y0–Y3; 2OE active HIGH controls Y0–Y3 on second bank. |
| 2, 4, 6, 8, 11, 13, 15, 17 | Data inputs (1A0–1A3, 2A0–2A3) | Eight asynchronous inputs grouped into two 4-bit banks; accept TTL-level signals directly. |
| 12, 14, 16, 18, 3, 5, 7, 9 | Data outputs (1Y0–1Y3, 2Y0–2Y3) | Non-inverting 3-state outputs; high-impedance when respective OE is inactive - enables bus sharing. |
| 10, 20 | GND (pin 10), VCC (pin 20) | Dedicated power/ground pins minimize switching noise coupling between logic banks. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient, including thermal cycling and humidity testing. |
| Dual independent 3-state control | Enables flexible bus partitioning: one bank can be isolated while the other remains active - critical for fault-tolerant designs. |
| TTL-compatible input thresholds | VIH = 2.0 V min / VIL = 0.8 V max ensures direct connection to legacy 5 V microcontrollers and sensors without level shifters. |
| Input clamp diodes | Permits safe interface to voltages > VCC (e.g., 12 V sensor lines) using series current-limiting resistors. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
Applications
| Body Control Module (BCM) | Instrument Cluster Interface |
|---|---|
|
Use Scenario: Isolating CAN/LIN transceiver I/O from MCU GPIOs during sleep mode to reduce leakage current. IC Role / Device Role / Timing Role: 3-state buffer enabling/disabling signal paths between microcontroller and communication peripherals.

IC Role / Device Role / Timing Role: Non-inverting line driver boosting current capability while maintaining logic polarity. Use Value: Delivers ±6 mA per output - sufficient to drive 20 mA LED strings via external current-limiting resistors. |
| Power Distribution Unit (PDU) | ADAS Camera Power Sequencing |
|
Use Scenario: Controlling multiple 5 V rail enable signals from a single microcontroller port with shared timing constraints. IC Role / Device Role / Timing Role: Octal buffer distributing synchronized enable commands to downstream DC-DC controllers. Use Value: Matched propagation delays (<22 ns) ensure simultaneous activation of power rails within <100 ns skew. |
Use Scenario: Managing reset and clock enable sequencing for image sensor and ISP during camera boot-up. IC Role / Device Role / Timing Role: Timing-controlled buffer gating clock/reset signals to avoid metastability in high-speed imaging paths. Use Value: 30 ns enable/disable times support sub-microsecond sequencing windows required by MIPI CSI-2 compliant sensors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT241QPWRQ1 | TI part; identical function, same AEC-Q100 Grade 1 rating, but uses different TSSOP-20 footprint (PW package vs SOT360-1). | Same automotive temperature range and electrical specs; differs in thermal resistance (RθJA = 105 K/W vs 110 K/W) and moisture sensitivity level (MSL 1 vs MSL 3). | Select if TI ecosystem alignment or existing PCB land pattern compatibility is prioritized. |
| 74LVCH241APWJ | Nexperia LVCH variant; 1.65–3.6 V supply, lower VIH (1.7 V), higher speed (tpd = 15 ns), but not AEC-Q100 qualified. | Not suitable for automotive under-hood use; appropriate only for interior infotainment modules with 3.3 V rails and no qualification requirement. | Choose only for cost-sensitive non-automotive applications where extended voltage range and higher speed outweigh qualification needs. |
Compared with SN74HCT241QPWRQ1, the 74HCT241PW-Q100 offers tighter thermal derating (10.0 mW/K above 100 °C) and MSL3 handling; versus 74LVCH241APWJ, it trades speed and voltage flexibility for guaranteed automotive reliability and system-level ESD robustness.

FAQ
Is the 74HCT241PW-Q100 pin-compatible with the industrial-grade 74HCT241PW?
Yes - the 74HCT241PW-Q100 shares identical pinout, electrical characteristics, and functional behavior with the industrial 74HCT241PW, differing only in AEC-Q100 qualification testing, extended temperature validation (−40 °C to +125 °C), and enhanced ESD/latch-up specifications required for automotive deployment.
Can 1OE and 2OE be tied together for single-enable operation?
Yes - connecting 1OE (active LOW) and 2OE (active HIGH) through an inverter enables unified 3-state control. Direct tying is electrically invalid due to opposing polarities, but a simple NOT gate (e.g., 74HCT04) provides clean synchronization without timing penalty (propagation delay <12 ns).
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 15 pF (per output) in dynamic tests, with typical transition time of 12 ns at 4.5 V. For loads exceeding 15 pF, output rise/fall times increase linearly; design margin requires limiting total net capacitance (including PCB trace + receiver input) to ≤30 pF to maintain <25 ns edge rates and avoid signal integrity issues.
Does the 74HCT241PW-Q100 support hot insertion or live bus swapping?
No - while input clamp diodes and high-impedance outputs support some degree of bus contention tolerance, the device lacks explicit hot-swap circuitry (e.g., slew-rate control, back-drive protection). Live insertion requires external current-limiting resistors and careful sequencing of VCC, GND, and signal lines per AEC-Q100 stress guidelines.
