Product details
Overview
74LVC241AD,118 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 and outputs, and Schmitt-trigger inputs for noise immunity. It enables bidirectional voltage translation between 3.3 V and 5 V logic domains in bus interface circuits.
For engineers reviewing the 74LVC241AD,118 datasheet, 74LVC241AD,118 pinout, 74LVC241AD,118 application, or 74LVC241AD,118 equivalent, key selection criteria include 5 V tolerance at both I/Os, dual active-Low/active-High output enable control (1OE/2OE), propagation delay ≤7.1 ns at 3.3 V, and operation across −40 °C to +125 °C industrial temperature range.
Technical Context
The 74LVC241AD,118 implements two independent 4-bit non-inverting buffers, each with dedicated output enable: 1OE (active LOW) controls outputs 1Y0–1Y3, while 2OE (active HIGH) controls 2Y0–2Y3. All eight inputs feature Schmitt-trigger action, enabling robust operation with slow-rising/falling signals up to 20 ns/V transition rate.
It supports mixed-voltage system interfacing: inputs accept 0–5.5 V regardless of VCC (1.2–3.6 V), and outputs tolerate up to 5.5 V in 3-state mode. The device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its full supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - Enables direct integration into low-voltage 1.8 V/2.5 V/3.3 V systems without level-shifting circuitry. |
| I/O Voltage Tolerance | 0 V to 5.5 V - Allows safe connection to legacy 5 V buses and mixed-voltage backplanes without external protection. |
| Propagation Delay | ≤7.1 ns at VCC = 3.0–3.6 V - Supports high-speed data transfer in address/data bus applications up to ~140 MHz. |
| Output Enable Timing | Enable/disable times ≤8.2 ns - Ensures precise bus arbitration and glitch-free bus sharing in multi-master systems. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLCs, and extended-temperature embedded controllers. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Reduces risk of handling damage and improves field reliability in uncontrolled environments. |
| Input Hysteresis | Schmitt-trigger inputs - Rejects noise on slow or noisy control lines (e.g., push-button debouncing, sensor interfaces). |
Pinout & Package
74LVC241AD,118 is housed in SO20 (SOT163-1) plastic small outline package: 20-pin, 7.5 mm body width, 1.27 mm pitch, surface-mount compatible.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE (Output Enable 1) | Active-LOW enable for outputs 1Y0–1Y3; drives all four outputs to high-impedance when HIGH. |
| 2,4,6,8 | 1A0–1A3 (Input Group 1) | Non-inverting data inputs for first buffer bank; Schmitt-triggered for noise immunity. |
| 10 | GND | Ground reference for all internal circuitry and I/Os; must be low-impedance for stable operation. |
| 12,14,16,18 | 1Y0–1Y3 (Output Group 1) | Non-inverting buffered outputs enabled by 1OE; 5 V tolerant in 3-state and driven states. |
| 19 | 2OE (Output Enable 2) | Active-HIGH enable for outputs 2Y0–2Y3; outputs go high-Z only when LOW. |
| 11,13,15,17 | 2A0–2A3 (Input Group 2) | Non-inverting data inputs for second buffer bank; independent timing and control from Group 1. |
| 3,5,7,9 | 2Y0–2Y3 (Output Group 2) | Non-inverting buffered outputs enabled by 2OE; supports independent bus segment control. |
| 20 | VCC | Primary power supply (1.2–3.6 V); powers all logic and output drivers; decoupling required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4-bit buffers | Enables simultaneous control of two separate 4-bit data paths (e.g., CPU address vs. data bus segments) with separate enable logic. |
| 5 V tolerant I/Os at any VCC | Eliminates need for external level shifters when interfacing 3.3 V microcontrollers to 5 V peripherals or legacy ASICs. |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis, allowing reliable operation with slow edges (e.g., RC-filtered reset lines, mechanical switch inputs). |
| Power-off high-impedance | Outputs remain high-Z even when VCC = 0 V, preventing back-driving of powered buses during hot-swap or partial power-down. |
| JEDEC-compliant voltage ranges | Guarantees interoperability with industry-standard 1.8 V, 2.5 V, and 3.3 V logic families per JESD8-7A/5A/C. |

FAQ
What is the maximum input voltage the 74LVC241AD,118 can safely accept?
The 74LVC241AD,118 accepts input voltages from −0.5 V to +5.5 V regardless of VCC level, enabling direct connection to 5 V logic without clamping diodes or external protection. This 5 V tolerance is guaranteed per JEDEC JESD8-C and applies across the full −40 °C to +125 °C operating range.
Does the 74LVC241AD,118 support hot insertion when VCC = 0 V?
Yes-the 74LVC241AD,118 features power-off high-impedance behavior: when VCC = 0 V, all outputs remain in high-impedance state even if input or output pins are driven to 5.5 V, preventing back-powering of the supply rail and protecting upstream circuitry during hot-swap operations.
How does the Schmitt-trigger input benefit system design with the 74LVC241AD,118?
The Schmitt-trigger inputs on the 74LVC241AD,118 provide built-in hysteresis (~0.3 V typical), rejecting noise and ensuring clean logic transitions on slow or noisy signals-such as those from mechanical switches, RC-debounced resets, or long cables-without requiring external filtering components.
Can the 74LVC241AD,118 drive standard TTL loads?
Yes-the 74LVC241AD,118 is specified to directly interface with TTL logic levels: its VOH exceeds 2.4 V and VOL stays below 0.4 V at 4 mA load and VCC ≥ 2.7 V, satisfying TTL input thresholds while consuming significantly less power than legacy 74LS devices.
What is the worst-case propagation delay for the 74LVC241AD,118 at 3.3 V operation?
At VCC = 3.0 V to 3.6 V and −40 °C to +125 °C, the maximum propagation delay (tpd) for the 74LVC241AD,118 is 7.1 ns for 1An→1Yn or 2An→2Yn paths, measured under standard test conditions (CL = 50 pF, RL = 500 Ω), ensuring timing predictability in high-speed digital interfaces.
