Product details
Overview
74LVC241AD,112 from NXP Semiconductors is an octal non-inverting 3-state buffer/line driver in SO20 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 and FPGA I/O expansion.
For engineers reviewing the 74LVC241AD,112 datasheet, 74LVC241AD,112 pinout, 74LVC241AD,112 application, or 74LVC241AD,112 equivalent, key selection criteria include 5 V tolerance on all I/O pins, dual independent 3-state enable (1OE active-low, 2OE active-high), propagation delay ≤7.1 ns at 3.3 V, and operation up to +125 °C ambient temperature.
Technical Context
The 74LVC241AD,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 operates across a wide supply range (1.2 V–3.6 V) while maintaining 5 V I/O tolerance, enabling direct TTL-level interfacing and safe hot-swap capability. The device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36, and features high-impedance outputs when VCC = 0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - enables operation in ultra-low-power and standard 3.3 V systems without level shifters |
| I/O Voltage Tolerance | Up to 5.5 V on all inputs and outputs - allows direct connection to legacy 5 V logic without external protection |
| Propagation Delay | ≤7.1 ns at VCC = 3.0–3.6 V - ensures timing-critical signal buffering in high-speed digital interfaces |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives |
| ESD Protection | HBM >2000 V, MM >200 V, CDM >1000 V - meets robustness requirements for assembly and field use |
| Input Hysteresis | Schmitt-trigger action - rejects noise on slow or noisy control lines such as pushbutton debouncing or sensor inputs |
| Power-Off Protection | High-impedance outputs when VCC = 0 V - prevents back-driving and bus contention during power sequencing |
Pinout & Package
74LVC241AD,112 uses the SO20 (SOT163-1) plastic small outline package: 20-pin, 7.5 mm body width, 1.27 mm pitch, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low output enable for Group 1 (1Y0–1Y3); asserts low to enable outputs |
| 2, 4, 6, 8 | 1A0–1A3 | Data inputs for Group 1; Schmitt-triggered for noise immunity |
| 10 | GND | Ground reference for all logic and power domains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC241APWRE4 | TSSOP20 package (4.4 mm width); identical electrical specs and pinout | Better suited for space-constrained PCBs; same thermal derating profile above 60 °C | Select when board area is limited and reflow compatibility with fine-pitch packages is required |
| 74LVC241ADB,118 | SSOP20 package (5.3 mm width); same SO20 pinout but smaller footprint and higher density | Higher pin density improves routing in multi-layer boards; slightly lower thermal mass | Choose for improved manufacturability in high-volume SMT lines where SSOP handling is standardized |

FAQ
What is the maximum input voltage the 74LVC241AD,112 can safely accept?
The 74LVC241AD,112 accepts input voltages up to 5.5 V regardless of VCC level, per its 5 V tolerant input specification. This allows direct connection to 5 V logic families without clamping diodes or external protection circuitry, even when VCC is as low as 1.2 V.
Does the 74LVC241AD,112 support hot-swap operation?
Yes - the 74LVC241AD,112 supports hot-swap operation because its outputs remain high-impedance and tolerate up to 5.5 V when disabled, and its inputs are 5 V tolerant. This prevents bus contention and latch-up when inserted into a live 5 V backplane.
What is the difference between 1OE and 2OE on the 74LVC241AD,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 asymmetry enables independent timing control - for example, enabling one group while disabling the other to stagger data transfers or isolate fault domains.
Can the 74LVC241AD,112 operate at 1.2 V supply?
Yes - the 74LVC241AD,112 is fully specified down to 1.2 V VCC, with propagation delay ≤14.1 ns and guaranteed logic thresholds. This makes it suitable for ultra-low-power applications such as battery-powered sensor nodes where minimizing supply voltage extends operational life.
Is the 74LVC241AD,112 pin-compatible with older 74-series buffers like the 74LS241?
No - the 74LVC241AD,112 is not pin-compatible with bipolar 74LS241. While both are octal 3-state buffers, the 74LVC241AD,112 has different pin assignments (e.g., dual OE inputs, split input/output groups) and CMOS-level thresholds. Direct replacement requires PCB layout revision.
