Product details
Overview
74HCT241PW,118 from Nexperia is an 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, supporting TTL-level inputs and delivering ±6 mA drive capability at VCC = 4.5 V, used for bidirectional bus interfacing in industrial control backplanes and legacy system upgrades.
For engineers reviewing the 74HCT241PW,118 datasheet, 74HCT241PW,118 pinout, 74HCT241PW,118 application, or 74HCT241PW,118 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), 3-state timing (ten = 15 ns typ, tdis = 18 ns typ at VCC = 4.5 V), thermal performance up to +125 °C, and TSSOP20 package compatibility with high-density PCB layouts.
Technical Context
The device implements two independent 4-bit buffered paths: inputs 1A0–1A3 feed outputs 1Y0–1Y3 under control of 1OE (active LOW), while 2A0–2A3 drive 2Y0–2Y3 via 2OE (active HIGH). Each output exhibits non-inverting logic and high-impedance OFF-state when its enable is inactive.
Input clamp diodes allow safe interfacing to voltages exceeding VCC using external current-limiting resistors. The 74HCT variant's reduced input thresholds ensure reliable recognition of standard TTL logic levels across the full −40 °C to +125 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation in 5 V TTL-compatible systems with ±10 % tolerance. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - Guarantees robust recognition of TTL logic levels without level-shifting circuitry. |
| Output Drive | ±6 mA at VCC = 4.5 V - Supports direct connection to standard CMOS/TTL loads without external buffers. |
| Propagation Delay | tpd = 13 ns typ (nAn → nYn) - Enables reliable data transfer at up to ~30 MHz clock rates in synchronous bus applications. |
| Enable Timing | ten = 15 ns typ, tdis = 18 ns typ - Allows fast bus arbitration and minimizes contention windows during multi-driver sharing. |
| Operating Temperature | −40 °C to +125 °C - Qualified for extended industrial environments including motor drives and power supply controllers. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Reduces risk of handling damage during assembly and field service. |
Pinout & Package
TSSOP20 plastic thin shrink small outline package (SOT360-1), 20-pin, body width 4.4 mm, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE (active LOW), 2OE (active HIGH) | Independent enables for two 4-bit output groups; allows selective bus isolation without global reset. |
| 2, 4, 6, 8, 17, 15, 13, 11 | 1A0–1A3, 2A0–2A3 | Eight buffered data inputs - split into two electrically isolated 4-bit lanes for flexible routing. |
| 18, 16, 14, 12, 3, 5, 7, 9 | 1Y0–1Y3, 2Y0–2Y3 | Non-inverting 3-state outputs - each pair shares no internal coupling, enabling independent bus loading. |
| 10 | GND | Ground reference for all I/O and supply - requires low-inductance connection to minimize switching noise. |
| 20 | VCC | Primary power supply - must be decoupled locally with ≥100 nF ceramic capacitor near pin 20. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-state controls | 1OE (LOW-enable) and 2OE (HIGH-enable) allow asymmetric bus arbitration - e.g., one group held active while other transitions. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5 V to 5.5 V - eliminates need for external level translators when interfacing 74LS or 74F families. |
| Input clamp diodes | Integrated diodes permit safe overvoltage input (up to VCC + 0.5 V) with external series resistors - simplifies mixed-voltage interface design. |
| High noise immunity | Typical noise margin > 0.8 V at VCC = 5 V - maintains signal integrity in electrically noisy industrial enclosures. |
| JEDEC-compliant packaging | SOT360-1 (TSSOP20) meets JESD22-A114 (HBM) and JESD22-C101 (CDM) standards - ensures reliability in automated SMT lines. |
Applications
| Industrial Backplane Interface | Legacy System Bus Extension |
|---|---|
Use Scenario: Interfacing microcontroller GPIO banks to a shared 8-bit parallel backplane carrying status and control signals across multiple PCBs in a PLC rack. IC Role / Device Role / Timing Role: Bidirectional buffer isolating MCU pins from bus capacitance and noise; 3-state control synchronizes with address decode to prevent contention. Use Value: Enables deterministic bus turnaround with <18 ns disable time, reducing arbitration latency and eliminating glitches during hot-swap events. | Use Scenario: Upgrading a 1990s CNC controller by replacing obsolete 74LS241 with pin-compatible modern logic while retaining original schematics and firmware. IC Role / Device Role / Timing Role: Drop-in TTL-level compatible buffer providing identical logic function and timing envelope within existing PCB footprint. Use Value: Eliminates obsolescence risk without redesign; same VIH/VIL specs and 13 ns propagation delay ensure bit-for-bit functional equivalence. |
| Motor Drive Control Logic | Test Equipment Signal Conditioning |
Use Scenario: Driving isolated gate drivers for three-phase IGBT modules, where logic-level signals must be conditioned before optocoupler input stages. IC Role / Device Role / Timing Role: Level-shifting and fan-out buffer between FPGA I/O and downstream isolation barriers; 3-state allows dynamic reconfiguration of control channels. Use Value: ±6 mA drive strength directly supports optocoupler LED forward current; 125 °C rating matches motor drive ambient requirements. | Use Scenario: Routing digital stimulus and response signals between ATE mainframe and DUT board, requiring clean edge integrity and minimal crosstalk in high-speed test fixtures. IC Role / Device Role / Timing Role: Signal integrity buffer placed at fixture entry point to restore rise/fall times degraded by long coaxial traces. Use Value: 5 ns transition time (tt) and 30 pF CPD limit dynamic power dissipation to <1.5 mW per channel at 10 MHz, preventing thermal drift in precision test setups. |
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 |
|---|---|---|---|
| 74HCT240PW,118 | Inverting outputs (vs. non-inverting 74HCT241); otherwise identical pinout, timing, and electrical specs. | Requires logic inversion in upstream/downstream circuitry; unsuitable where signal polarity must be preserved end-to-end. | Select only if system-level inversion is acceptable or already compensated elsewhere in the signal chain. |
| SN74HCT241PWR | Same logic function and pinout; TI version uses SOIC-20 (not TSSOP20) and specifies slightly tighter VOH/VOL at VCC = 4.75 V. | Larger SOIC package increases PCB area use; different thermal resistance (109 °C/W vs. 100 °C/W for TSSOP) affects high-temp derating. | Prefer when legacy SOIC footprint compatibility is required; avoid if board space or thermal density constraints favor TSSOP. |
Compared with 74HCT241PW,118, the 74HCT240PW,118 offers identical timing but inverted outputs-requiring schematic revision-while SN74HCT241PWR provides functional equivalence in SOIC-20, trading compactness and thermal efficiency for broader distributor availability.

FAQ
What is the maximum recommended supply voltage for 74HCT241PW,118?
The absolute maximum supply voltage is +7 V, but the recommended operating range is strictly 4.5 V to 5.5 V. Operation above 5.5 V violates JEDEC JESD8C compliance and risks accelerated parametric shift or latch-up, especially at elevated temperatures. Designers must maintain VCC within this window to guarantee VIH/VIL thresholds and output drive specifications.
Can 74HCT241PW,118 drive a 50 pF capacitive load at 10 MHz without signal degradation?
Yes - with typical propagation delay of 13 ns and transition time of 5 ns, the device maintains clean edges into 50 pF loads at 10 MHz. Dynamic power dissipation remains below 1.5 mW per channel (CPD = 30 pF), and output drive (±6 mA) exceeds the 0.5 mA required to charge/discharge 50 pF in 5 ns, ensuring monotonic edges without overshoot or ringing.
How does the dual-enable architecture improve bus arbitration compared to single-enable octal buffers?
The independent 1OE (active LOW) and 2OE (active HIGH) allow simultaneous control of two 4-bit sub-buses with opposite polarity logic - e.g., one group enabled during address phase (1OE = LOW), the other during data phase (2OE = HIGH). This eliminates inter-group timing skew and reduces arbitration logic complexity versus cascaded enable decoding.
Is 74HCT241PW,118 qualified for automotive applications?
No - the device is specified for industrial temperature range (−40 °C to +125 °C) but is not AEC-Q100 qualified. It lacks automotive-specific stress testing, failure rate reporting, and PPAP documentation. For automotive use, Nexperia's automotive-grade 74AHCT241 variants (e.g., 74AHCT241PWJ) must be selected instead.
