Product details
Overview
74LVC241APW,112 from NXP Semiconductors is an octal non-inverting 3-state buffer/line driver in TSSOP20 package, operating from 1.2 V to 3.6 V supply, with 5 V tolerant inputs/outputs and Schmitt-trigger inputs for noise immunity. It supports mixed-voltage interfacing between 3.3 V and 5 V logic domains in industrial control backplanes.
For engineers reviewing the 74LVC241APW,112 datasheet, 74LVC241APW,112 pinout, 74LVC241APW,112 application, or 74LVC241APW,112 equivalent, key selection criteria include 3-state dual-enable control (1OE active-low, 2OE active-high), propagation delay ≤7.1 ns at 3.3 V, and operation across −40 °C to +125 °C.
Technical Context
The 74LVC241APW,112 implements two independent 4-bit non-inverting buffer groups (1A0–1A3 → 1Y0–1Y3 and 2A0–2A3 → 2Y0–2Y3), each controlled by separate output enable signals (1OE active-low, 2OE active-high). Its Schmitt-trigger inputs accept slow-rising/falling waveforms and tolerate input voltages up to 5.5 V regardless of VCC level.
It complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), and features high-impedance outputs when VCC = 0 V - enabling live insertion and bus isolation in hot-swap systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families without level shifters. |
| Input voltage tolerance | −0.5 V to +5.5 V - allows safe connection to 5 V TTL/CMOS sources while powered from 3.3 V or lower. |
| Propagation delay | ≤7.1 ns at VCC = 3.0–3.6 V - ensures timing-critical data path integrity in high-speed digital interfaces. |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple LVC/LVT inputs. |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLCs, and telecom infrastructure. |
| ESD protection | HBM >2000 V, MM >200 V, CDM >1000 V - meets IEC 61000-4-2 system-level robustness requirements. |

Pinout & Package
TSSOP20 package (SOT360-1): plastic thin shrink small outline, 20 leads, body width 4.4 mm, 0.65 mm pitch, lead finish matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE (output enable) | Active-low enable for Group 1 outputs (1Y0–1Y3); asserts high-impedance state when HIGH. |
| 2, 4, 6, 8 | 1A0–1A3 | Data inputs for Group 1; Schmitt-triggered for noise immunity on slow edges. |
| 10 | GND | Ground reference for all logic and power domains; must be low-inductance connection. |
| 11, 13, 15, 17 | 2A0–2A3 | Data inputs for Group 2; electrically isolated from Group 1 but share same VCC/GND. |
| 12, 14, 16, 18 | 1Y0–1Y3 | Non-inverting buffered outputs for Group 1; 3-state capable, 5 V tolerant. |
| 3, 5, 7, 9 | 2Y0–2Y3 | Non-inverting buffered outputs for Group 2; independently enabled via 2OE (pin 19). |
| 19 | 2OE | Active-high enable for Group 2 outputs (2Y0–2Y3); complements 1OE polarity for flexible bus control. |
| 20 | VCC | Core supply (1.2–3.6 V); decoupling capacitor (100 nF) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-state control | Separate 1OE (active-low) and 2OE (active-high) pins allow asymmetric bus arbitration and partial bus isolation. |
| 5 V tolerant I/O | Inputs and outputs withstand 5.5 V regardless of VCC (1.2–3.6 V), eliminating external level translators in mixed-voltage systems. |
| Schmitt-trigger inputs | Hysteresis ≥0.3 V at VCC = 3.3 V improves noise margin against ground bounce and EMI in noisy industrial environments. |
| Zero-power shutdown | IOFF leakage ≤±20 µA at VCC = 0 V enables true power-off isolation without signal contention on shared buses. |
| JEDEC-compliant voltage ranges | Validated operation across three JEDEC sub-ranges (1.65–1.95 V, 2.3–2.7 V, 2.7–3.6 V) ensures compatibility with legacy and next-gen logic families. |

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 |
|---|---|---|---|
| SN74LVC241APWR (TI) | Identical pinout and electrical specs; rated only to +85 °C (not +125 °C); slightly higher ICC (max 40 µA vs. 10 µA at VCC = 3.6 V). | Limited to commercial/industrial ambient (−40 °C to +85 °C); unsuitable for under-hood or high-temp enclosure use. | Select 74LVC241APW,112 when extended temperature operation or ultra-low static current is required. |

FAQ
What is the maximum input voltage the 74LVC241APW,112 can safely accept?
The 74LVC241APW,112 accepts input voltages from −0.5 V to +5.5 V, independent of VCC level. This 5 V tolerance allows direct connection to 5 V TTL or CMOS sources even when powered from 1.8 V or 3.3 V, eliminating external level-shifting components in mixed-voltage designs.
Does the 74LVC241APW,112 support hot-swap operation?
Yes - the 74LVC241APW,112 exhibits high-impedance behavior when VCC = 0 V (IOFF ≤±20 µA), enabling safe insertion into live backplanes. Its 5 V tolerant I/O and dual 3-state enables prevent bus contention during power-up/down sequences in modular systems.
How does the Schmitt-trigger input benefit the 74LVC241APW,112 in real-world applications?
The Schmitt-trigger inputs on the 74LVC241APW,112 provide ≥0.3 V hysteresis at 3.3 V, rejecting noise, ground bounce, and slow-rising signals common in industrial sensors or long PCB traces. This eliminates false triggering and reduces need for external RC filtering in harsh EMI environments.
Can the 74LVC241APW,112 drive standard 50 Ω transmission lines?
Yes - the 74LVC241APW,112 delivers ±24 mA output drive at VCC = 3.0 V, sufficient to terminate and drive 50 Ω lines directly. Measured tpd ≤7.1 ns and tsK(o) ≤1.5 ns ensure clean edge integrity without excessive ringing or skew across all eight channels.
What is the difference between 1OE and 2OE on the 74LVC241APW,112?
1OE (pin 1) is active-low and controls Group 1 outputs (1Y0–1Y3); 2OE (pin 19) is active-high and controls Group 2 outputs (2Y0–2Y3). This complementary polarity allows independent, asymmetric bus arbitration - e.g., one group held active while the other is tristated - without external logic inversion.
