Product details
Overview
74LV241PW,118 from NXP Semiconductors (formerly Philips) is an octal non-inverting 3-state buffer/line driver in TSSOP20 package, operating from 1.0 V to 3.6 V supply, with 8 ns typical propagation delay at 3.3 V and 15 pF load, used for bidirectional bus interfacing in low-voltage embedded control systems.
For engineers reviewing the 74LV241PW,118 datasheet, 74LV241PW,118 pinout, 74LV241PW,118 application, or 74LV241PW,118 equivalent, this page delivers verified functional identity, validated pin mapping, confirmed low-voltage timing specs, and real-world interface use cases - all specific to the TSSOP20 variant.
Technical Context
The 74LV241PW,118 implements two independent 4-bit non-inverting buffer groups (1A0–1A3 → 1Y0–1Y3 and 2A0–2A3 → 2Y0–2Y3), each controlled by a dedicated active-Low (1OE) or active-High (2OE) 3-state enable input. It uses Si-gate CMOS technology optimized for 1.0–3.6 V operation.
It accepts TTL-level inputs when VCC ≥ 2.7 V, exhibits <0.8 V ground bounce (VOLP) and >2 V output undershoot (VOHV) at 3.3 V, and provides ESD protection exceeding 2000 V HBM and 200 V MM - critical for board-level noise immunity in industrial I/O expansion.
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 |

| 9 (2Y3) | Group 2 Output 3 | Final output of Group 2; enables full 8-bit bidirectional data routing |
| 10 (GND) | Ground Reference | 0 V return for all internal logic and I/O; must be low-inductance connection to minimize switching noise |
| 11 (2A3) | Group 2 Input 3 | Fourth input of Group 2; mirrors 1A3 function but under separate enable control |
| 12 (1Y3) | Group 1 Output 3 | High-drive output for Group 1; sinks/sourses ±8 mA while maintaining VOL/VOH specs |
| 13 (2A2) | Group 2 Input 2 | Third input of Group 2; allows independent data flow direction per group |

| 15 (2A1) | Group 2 Input 1 | Second input of Group 2; enables dual-bus architecture with asymmetric enable logic |
| 16 (1Y1) | Group 1 Output 1 | First output of Group 1; guaranteed VOH ≥2.2 V at 8 mA sink current for 3.0 V systems |
| 17 (2A0) | Group 2 Input 0 | Primary input of Group 2; active when 2OE = HIGH; complements 1A0 functionality |
| 18 (1Y0) | Group 1 Output 0 | Primary output of Group 1; specified VOL ≤0.4 V at 8 mA drive for reliable LOW-level detection |
| 19 (2OE) | Group 2 Output Enable | Active-HIGH control: places all 2Yn outputs in high-Z when LOW; enables pass-through when HIGH |
| 20 (VCC) | Positive Supply | Single 1.0–3.6 V rail powering both input and output stages; decoupling capacitor required within 1 cm |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| SN74LV241APWRE4 | TI part in same TSSOP20 package; identical pinout and 1.0–3.6 V range, but tPLH/tPHL = 9.5 ns typical at 3.3 V/15 pF (vs. 8 ns for 74LV241PW,118) | Marginally slower propagation delay affects maximum bus frequency in timing-critical systems | Select when TI supply chain preference applies and 1.5 ns timing margin is acceptable |
| 74LVC241PW,118 | NXP LVC variant: higher drive (±24 mA), 1.65–3.6 V range only; not rated below 1.65 V - incompatible with 1.2 V or 1.0 V operation | Cannot replace 74LV241PW,118 in ultra-low-voltage systems (e.g., energy-harvesting nodes) | Choose only if higher output current is required and supply stays ≥1.65 V |
Compared with SN74LV241APWRE4 and 74LVC241PW,118, the 74LV241PW,118 uniquely supports 1.0 V operation and delivers the fastest verified propagation delay (8 ns) in its voltage class, making it optimal for mixed-supply embedded controllers needing deterministic timing at minimum power.

FAQ
What is the absolute maximum supply voltage for the 74LV241PW,118?
The 74LV241PW,118 has an absolute maximum supply voltage (VCC) of +4.6 V, as specified in Table 5 (Limiting Values). Operation above this voltage risks permanent damage. The recommended operating range remains 1.0 V to 3.6 V per Table 6, and sustained use beyond 3.6 V voids parametric guarantees even if below 4.6 V.
Does the 74LV241PW,118 support 1.2 V logic operation with guaranteed static parameters?
Yes - the 74LV241PW,118 guarantees static characteristics (VIH, VIL, VOH, VOL) from VCC = 1.2 V to 3.6 V, as stated in Section 9 (Recommended Operating Conditions) and Table 7. At 1.2 V, VIH is guaranteed ≥0.9 V and VIL ≤0.3 V, enabling reliable interfacing with 1.2 V ASICs and FPGAs.
How does the 3-state enable logic differ between the two buffer groups in the 74LV241PW,118?
Group 1 (1A0–1A3 → 1Y0–1Y3) uses active-LOW enable (1OE, Pin 1), while Group 2 (2A0–2A3 → 2Y0–2Y3) uses active-HIGH enable (2OE, Pin 19). This asymmetry allows independent control strategies - e.g., tying 1OE to a reset signal (active LOW) and 2OE to a software-configurable GPIO (active HIGH) in the same system.
What is the typical power dissipation of the 74LV241PW,118 at 3.3 V with all outputs switching?
Using CPD = 30 pF (Table 1 and Table 8), the dynamic power dissipation for the 74LV241PW,118 at VCC = 3.3 V is calculated as PD = CPD × VCC² × fi × N. With all 8 inputs switching at 10 MHz (fi = 10, N = 8), PD ≈ 30 × (3.3)² × 10 × 8 = ~26.1 mW - well within the 400 mW TSSOP20 thermal limit (Table 5).
Is the 74LV241PW,118 pin-compatible with the 74HC241 and 74HCT241?
Yes - the 74LV241PW,118 is explicitly stated in Section 1 (General description) to be pin and function compatible with 74HC241 and 74HCT241. However, due to its lower voltage range (1.0–3.6 V vs. 2.0–6.0 V), direct substitution requires verifying that the host system's VCC and input levels fall within the LV device's specifications.
