Product details
Overview
74AHC241PW,118 from Nexperia is an 8-bit CMOS buffer/line driver with dual 3-state outputs and overvoltage-tolerant inputs, operating from 2.0 V to 5.5 V supply. It functions as two independent 4-bit buffers (Group 1: A0–A3 → Y0–Y3; Group 2: A0–A3 → Y0–Y3) with separate active-low (1OE) and active-high (2OE) enables, enabling bidirectional bus isolation in mixed-voltage digital systems such as industrial I/O expansion modules.
For engineers reviewing the 74AHC241PW,118 datasheet, 74AHC241PW,118 pinout, 74AHC241PW,118 application, or 74AHC241PW,118 equivalent, key selection criteria include its 3.2 ns typical propagation delay at 5 V/15 pF, ±25 mA output drive capability, Schmitt-trigger input hysteresis for noise immunity, and −40 °C to +125 °C automotive-grade temperature range.
Technical Context
The 74AHC241PW,118 implements a dual-group 3-state buffer architecture with independent enable control per group: 1OE (Pin 1, active LOW) governs outputs Y0–Y3, while 2OE (Pin 19, active HIGH) controls Y0–Y3. Inputs accept voltages up to 7.0 V regardless of VCC, supporting level translation between 3.3 V and 5 V domains without external circuitry.
All inputs feature Schmitt-trigger action with hysteresis (typ. 0.3 V at VCC = 5 V), improving noise rejection on slow or noisy signals. The device complies with JEDEC JESD22-A114F (HBM >2 kV) and JESD22-C101D (CDM >1 kV) ESD standards, ensuring robustness in handling and board assembly environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 2.0 V to 5.5 V - supports single-supply operation across 3.3 V and 5 V logic families without level shifters. |
| Propagation Delay (tpd) | 3.2 ns (typ.) at VCC = 5 V, CL = 15 pF - enables high-speed data buffering in timing-critical interfaces like parallel ADC/DAC buses. |
| Output Drive (IO) | ±25 mA - sufficient to directly drive multiple TTL loads or terminate short PCB traces without external drivers. |
| Input Voltage Range (VI) | −0.5 V to +7.0 V - allows safe interfacing with higher-voltage peripherals (e.g., 5 V sensors on 3.3 V MCU buses). |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and outdoor embedded applications. |
| Input Capacitance (CI) | 3 pF (typ.) - minimizes capacitive loading on upstream drivers, preserving signal integrity in high-frequency bus designs. |
| Power Dissipation Cap. (CPD) | 9 pF - used to calculate dynamic power: PD = CPD × VCC² × fi × N, critical for thermal budgeting in dense layouts. |
Pinout & Package
TSSOP20 package (SOT360-1): plastic thin shrink small outline, 20 leads, body width 4.4 mm, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OE) | Group 1 Output Enable (active LOW) | Asserting LOW enables Y0–Y3; HIGH places them in high-impedance state - isolates first 4-bit bus segment. |
| 2, 4, 6, 8 (1A0–1A3) | Group 1 Data Inputs | Non-inverting inputs for first 4-bit channel; tolerate VI up to 7.0 V independent of VCC. |
| 12, 14, 16, 18 (1Y0–1Y3) | Group 1 Data Outputs | 3-state buffered outputs; drive strength ±25 mA; VOH/VOL specified down to VCC = 2.0 V. |
| 11, 13, 15, 17 (2A0–2A3) | Group 2 Data Inputs | Non-inverting inputs for second 4-bit channel; identical voltage tolerance and Schmitt characteristics as Group 1. |
| 3, 5, 7, 9 (2Y0–2Y3) | Group 2 Data Outputs | 3-state outputs controlled by 2OE (Pin 19); share same electrical specs and timing as Group 1 outputs. |
| 10 (GND) | Ground Reference | 0 V reference for all I/O and internal logic; must be low-impedance connection to minimize ground bounce. |
| 19 (2OE) | Group 2 Output Enable (active HIGH) | Asserting HIGH enables Y0–Y3; LOW disables - enables asymmetric enable logic (e.g., one group always active). |
| 20 (VCC) | Power Supply | Primary supply for logic core and output drivers; decoupling capacitor (100 nF) required within 5 mm of Pin 20. |
Key Features
| Feature | Design Value |
|---|---|
| Balanced propagation delays | tpd variation ≤ 1.5 ns between channels ensures deterministic timing alignment in parallel data paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT241PW,118 | TTL-compatible inputs (VIH = 2.0 V min), fixed 4.5–5.5 V VCC range - no 3.3 V operation. | Required where legacy 5 V TTL logic drives inputs; unsuitable for mixed 3.3 V/5 V systems. | Select only when interfacing exclusively with 5 V TTL sources and VCC is fixed at 5 V. |
| SN74LVC241APW | Lower VCC range (1.65–3.6 V), 32 mA drive, but VI max = VCC + 0.3 V - no overvoltage tolerance. | Optimized for 3.3 V-only portable electronics; cannot interface with 5 V peripherals without external protection. | Prefer for battery-powered 3.3 V systems where ultra-low static current (< 1 μA) is critical and voltage translation is unnecessary. |

FAQ
What is the maximum input voltage the 74AHC241PW,118 can tolerate?
The 74AHC241PW,118 supports input voltages from −0.5 V to +7.0 V, independent of VCC. This overvoltage tolerance allows safe interfacing with 5 V peripherals on a 3.3 V-powered system without external clamping diodes or level shifters, simplifying design and improving robustness against supply rail mismatches.
Does the 74AHC241PW,118 support operation at 3.3 V supply?
Yes, the 74AHC241PW,118 is fully specified for VCC = 2.0 V to 5.5 V, including 3.3 V operation. At VCC = 3.3 V, it delivers typical propagation delay of 4.5 ns (CL = 15 pF) and maintains VIH = 2.1 V (min) and VIL = 0.9 V (max), ensuring compatibility with standard 3.3 V CMOS logic families.
How does the dual output enable (1OE and 2OE) function in the 74AHC241PW,118?
In the 74AHC241PW,118, 1OE (Pin 1) is active LOW and controls outputs Y0–Y3, while 2OE (Pin 19) is active HIGH and controls outputs Y0–Y3. This asymmetry allows independent, simultaneous control of two 4-bit data paths - for example, enabling one group while disabling the other to prevent bus contention in multiplexed architectures.
What is the significance of Schmitt-trigger inputs in the 74AHC241PW,118?
Schmitt-trigger inputs in the 74AHC241PW,118 provide hysteresis (≥0.3 V at VCC = 5 V), rejecting noise on slow-rising or electrically noisy signals. This eliminates false triggering in industrial environments with EMI, removes the need for external RC filters, and ensures clean, jitter-free output transitions even with marginal input slew rates.
Is the 74AHC241PW,118 suitable for automotive applications?
Yes, the 74AHC241PW,118 is qualified for operation from −40 °C to +125 °C and meets AEC-Q100 stress test requirements for logic devices. Its high ESD robustness (HBM >2 kV), overvoltage-tolerant inputs, and stable timing across temperature make it suitable for body control modules, infotainment interfaces, and powertrain subsystems in modern vehicles.
