Product details
Overview
74LV241N,112 from NXP Semiconductors (formerly Philips) is an octal non-inverting buffer/line driver with dual 3-state outputs, designed for low-voltage digital bus interfacing in industrial and embedded systems. It operates from 1.0 V to 3.6 V supply, delivers 8 ns propagation delay at 3.3 V/15 pF, supports TTL-level inputs at VCC ≥ 2.7 V, and features active-low (1OE) and active-high (2OE) independent output enables.
For engineers reviewing the 74LV241N,112 datasheet, 74LV241N,112 pinout, 74LV241N,112 application, or 74LV241N,112 equivalent, this device serves as a voltage-scalable, pin-compatible upgrade path from 74HC241/74HCT241 in space-constrained DIP20 layouts requiring robust ground bounce (<0.8 V) and undershoot (>2 V) control at 3.3 V operation.
Technical Context
The 74LV241N,112 implements two independent 4-bit non-inverting buffer groups (1A0–1A3 → 1Y0–1Y3 and 2A0–2A3 → 2Y0–2Y3), each controlled by separate 3-state enable inputs (1OE active LOW, 2OE active HIGH). Its Si-gate CMOS process ensures rail-to-rail output swing and low static current (≤160 µA at 3.6 V).
It meets IEC 60134 absolute maximum ratings, including −0.5 V to +4.6 V supply voltage, ±35 mA output drive, and ESD protection exceeding 2000 V HBM and 200 V MM. Input thresholds are specified across 1.2 V–3.6 V VCC, with VIH = 2.0 V and VIL = 0.8 V typical at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 3.6 V - Enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Propagation Delay (tPLH/tPHL) | 8 ns max at VCC = 3.3 V, CL = 15 pF - Supports >100 MHz bus toggle rates in high-speed digital backplanes. |
| 3-State Enable/Disable Time | 10 ns / 13 ns typical at VCC = 3.3 V - Ensures clean bus arbitration with minimal contention window during output state transitions. |
| Output Drive Capability | ±8 mA at VCC = 3.0 V - Sufficient to drive 15 pF loads across 20 cm PCB traces or 2–3 standard CMOS inputs. |
| Input Capacitance (Ci) | 3.5 pF - Minimizes capacitive loading on upstream drivers, preserving signal integrity in fan-out-critical designs. |
| Quiescent Supply Current (ICC) | 160 µA max at VCC = 3.6 V - Enables low-power standby modes in battery-backed or energy-sensitive applications. |
| ESD Protection | HBM >2000 V, MM >200 V - Provides robust handling margin during board assembly and field service without external protection diodes. |
Pinout & Package
DIP20 plastic dual in-line package (SOT146-1), 300 mil width, 20-pin through-hole mount with 2.54 mm pitch; suitable for prototyping, legacy industrial controls, and wave-soldered assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OE) | Group 1 Output Enable | Active-LOW control: pulls all 1Yn outputs to high-impedance when HIGH; enables non-inverting pass-through when LOW. |
| 2–5, 11–14 (1A0–1A3, 2A0–2A3) | Data Inputs | Two independent 4-bit input buses; tolerant of TTL input levels when VCC ≥ 2.7 V. |
| 3, 5, 7, 9, 12, 14, 16, 18 (2Y0–2Y3, 1Y0–1Y3) | Buffered Outputs | Non-inverting outputs with 3-state capability; VOH ≥ 2.82 V and VOL ≤ 0.40 V at 8 mA load (VCC = 3.0 V). |
| 10 (GND) | Ground Reference | Primary 0 V return path; decoupling capacitor must be placed within 5 mm for stable 3-state switching. |
| 19 (2OE) | Group 2 Output Enable | Active-HIGH control: enables 2Yn outputs only when HIGH; allows independent bus isolation from Group 1. |
| 20 (VCC) | Supply Voltage | Single 1.0–3.6 V rail; requires local 100 nF ceramic bypass capacitor between Pin 20 and Pin 10. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range (1.0 V–3.6 V) | Supports mixed-voltage system integration without external regulators or level translators. |
| TTL-Compatible Inputs | Accepts standard 0 V/5 V TTL signals at VCC ≥ 2.7 V, enabling interoperability with legacy controllers. |
| Low Ground Bounce (VOLP < 0.8 V) | Reduces noise coupling into adjacent signal lines and analog sections during simultaneous output switching. |
| Independent Dual 3-State Control | Enables bidirectional bus management using 1OE (active LOW) and 2OE (active HIGH) for flexible timing alignment. |
| High ESD Robustness | HBM >2000 V rating eliminates need for external ESD protection in most industrial handling environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LV241D,118 | SO20 surface-mount package (7.5 mm body width); identical electrical specs and pinout. | Required for reflow-soldered PCBs; not compatible with through-hole sockets or breadboards. | Select when board space is constrained and automated assembly is used. |
| SN74LV241APWR | Texas Instruments TSSOP20 package; same 1.0–3.6 V range and 8 ns tPLH, but IOZ leakage up to 10 µA vs. 5 µA max for 74LV241N,112. | Suitable for high-density consumer PCBs; slightly higher OFF-state current may affect ultra-low-power sleep modes. | Choose for TI-design ecosystems or where TSSOP footprint aligns with existing layout standards. |
Compared with 74LV241D,118 and SN74LV241APWR, the 74LV241N,112 offers through-hole mechanical reliability and lowest 3-state leakage (5 µA), making it optimal for prototyping, repair, and industrial control panels where socketing and long-term contact stability are critical.

FAQ
What is the maximum operating supply voltage for the 74LV241N,112?
The 74LV241N,112 has an absolute maximum supply voltage (VCC) of +4.6 V per IEC 60134 limiting values, but its recommended operating range is strictly 1.0 V to 3.6 V. Operation above 3.6 V voids guaranteed performance and risks permanent damage; the 74LV241N,112 is not rated for 5 V operation.
Does the 74LV241N,112 support TTL input levels?
Yes - the 74LV241N,112 accepts standard TTL input voltage levels (0 V to 5 V) when VCC is between 2.7 V and 3.6 V, as confirmed in Section 9 (Recommended Operating Conditions) and Table 7 (Static Characteristics) of the datasheet. This allows direct connection to legacy 5 V logic without level shifters.
What is the function of Pin 1 (1OE) and Pin 19 (2OE) on the 74LV241N,112?
Pin 1 (1OE) is the active-LOW enable for outputs 1Y0–1Y3; when LOW, those outputs follow their respective 1A0–1A3 inputs; when HIGH, they enter high-impedance state. Pin 19 (2OE) is the active-HIGH enable for outputs 2Y0–2Y3; it functions identically but with opposite polarity - the 74LV241N,112 uses this dual-polarity scheme for flexible bus timing control.
Can the 74LV241N,112 replace a 74HC241 in an existing design?
Yes - the 74LV241N,112 is explicitly stated as pin and function compatible with 74HC241 and 74HCT241 in the General Description. However, verify VCC is reduced to ≤3.6 V (not 5 V), and confirm that the lower drive strength (±8 mA vs. ±25 mA for HC) meets load requirements; the 74LV241N,112 remains fully functional in most HC-based layouts with minor power rail adjustment.
What is the thermal derating behavior of the 74LV241N,112 in DIP20 package?
In the DIP20 (SOT146-1) package, the 74LV241N,112 has a total power dissipation limit of 750 mW at Tamb ≤ 70 °C; above 70 °C, Ptot derates linearly at 12 mW/K. At 125 °C ambient, maximum allowable power drops to approximately 750 mW − (55 K × 12 mW/K) = 80 mW - requiring careful thermal design in high-temperature enclosures.
