Product details
Overview
74LV241PW,112 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,112 datasheet, 74LV241PW,112 pinout, 74LV241PW,112 application, or 74LV241PW,112 equivalent, this device supports TTL-level input compatibility at VCC ≥ 2.7 V, delivers ±35 mA output drive, and enables dual independent 4-bit bus segments via active-low 1OE and active-high 2OE controls - critical for power-sensitive industrial I/O expansion and memory address buffering.
Technical Context
The 74LV241PW,112 implements two independent 4-bit non-inverting buffer groups (1A0–1A3 → 1Y0–1Y3 and 2A0–2A3 → 2Y0–2Y3), each with dedicated 3-state enable logic: 1OE (pin 1, active LOW) and 2OE (pin 19, active HIGH). Its Si-gate CMOS process ensures rail-to-rail output swing and low ground bounce (VOLP < 0.8 V) at 3.3 V.
It operates across −40 °C to +125 °C ambient temperature, supports dynamic power calculation via CPD = 30 pF, and meets IEC 60134 absolute maximum ratings including VCC up to +4.6 V and output current up to ±35 mA - enabling robust use in automotive body control modules and programmable logic interface layers.
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 typical at VCC = 3.3 V, CL = 15 pF - supports >100 MHz data throughput in buffered address/data paths. |
| Output Drive Strength | ±35 mA per output - sufficient to drive 50 pF loads over 10 cm PCB traces or terminate multiple CMOS inputs. |
| Input Capacitance (Ci) | 3.5 pF - minimizes capacitive loading on upstream drivers, preserving signal integrity in high-speed fanout. |
| Power Dissipation Capacitance (CPD) | 30 pF - allows accurate dynamic power estimation using PD = CPD × VCC² × fi × N + Σ(CL × VCC² × fo). |
| 3-State Enable/Disable Time | 10 ns typical enable (tPZL/tPZH), 13 ns typical disable (tPLZ/tPHZ) at 3.3 V - ensures clean bus arbitration without contention glitches. |
| ESD Protection | HBM > 2000 V, MM > 200 V - provides handling robustness during automated assembly and field service. |
Pinout & Package
TSSOP20 package (SOT360-1): plastic thin shrink small outline, 20 leads, 4.4 mm body width, 0.65 mm pitch, exposed pad not present, RoHS-compliant.
| 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; accept TTL-compatible thresholds at 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; VOL ≤ 0.4 V at 8 mA sink, VOH ≥ 2.2 V at 8 mA source (VCC = 3.0 V). |
| 10 (GND) | Ground Reference | Primary 0 V return path; decoupling capacitor must be placed within 5 mm of pin 10 and pin 20. |
| 19 (2OE) | Group 2 Output Enable | Active-HIGH control: enables 2Yn outputs when HIGH; disables to high-Z when LOW - complementary timing to 1OE. |
| 20 (VCC) | Supply Voltage | Single 1.0–3.6 V rail; total power dissipation limited to 400 mW at Tamb ≤ 60 °C, derating 5.5 mW/K above. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.0 V to 3.6 V operation - eliminates need for separate voltage regulators in mixed-supply systems. |
| TTL Input Compatibility | Valid VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 2.7–3.6 V - allows direct connection to legacy 5 V TTL outputs via pull-up resistors or direct interfacing. |
| Low Ground Bounce | VOLP < 0.8 V at VCC = 3.3 V - reduces noise coupling into adjacent analog or RF sections during switching. |
| High-Speed 3-State Control | tPZL/tPZH = 10 ns typical - enables glitch-free bus sharing between microcontrollers and peripherals in real-time control loops. |
| Industrial Temperature Range | −40 °C to +125 °C - qualified for under-hood automotive, motor drive gate driver interfaces, and industrial PLC backplanes. |

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 |
|---|---|---|---|
| SN74LV241APWR | TI part in TSSOP20; identical pinout and logic function; wider VCC range (1.65–5.5 V); higher ICC max (160 µA vs. 20 µA at 3.6 V). | Supports 5 V legacy systems; less suitable for sub-1.65 V ultra-low-power designs where 74LV241PW,112 operates down to 1.0 V. | Select SN74LV241APWR only if 5 V tolerance or higher drive at 5 V is required; otherwise 74LV241PW,112 offers superior low-VCC efficiency. |
| 74LVC241PW,118 | NXP part in same TSSOP20 package; 1.65–3.6 V range; faster tPLH/tPHL (5.2 ns typ. at 3.3 V); lower CPD (22 pF). | Optimized for speed-critical 3.3 V systems; cannot operate below 1.65 V, excluding 1.2 V or 1.8 V core domains. | Choose 74LVC241PW,118 when propagation delay <6 ns is mandatory and supply is fixed at ≥1.65 V; retain 74LV241PW,112 for universal low-voltage flexibility. |
Compared with SN74LV241APWR and 74LVC241PW,118, the 74LV241PW,112 uniquely supports 1.0 V operation - making it the only option for battery-powered devices scaling supply voltage dynamically, while maintaining pin compatibility and identical 3-state timing behavior across all three parts.

FAQ
What is the minimum supply voltage at which 74LV241PW,112 guarantees functional operation?
The 74LV241PW,112 guarantees full functionality down to 1.0 V supply voltage, with static characteristics specified from 1.2 V to 3.6 V. At 1.0 V, it supports basic logic operation (HIGH/LOW recognition), though propagation delay increases to 45 ns typical. This enables direct integration with ultra-low-power microcontrollers operating in deep-sleep modes.
Does 74LV241PW,112 support TTL-level input signals when powered at 3.3 V?
Yes - when VCC is 2.7 V to 3.6 V, the 74LV241PW,112 accepts standard TTL input levels: VIH ≥ 2.0 V (for HIGH recognition) and VIL ≤ 0.8 V (for LOW recognition). This allows direct connection to 5 V TTL outputs without external level-shifting circuitry, provided input current limits are observed.
How are the two output enable controls (1OE and 2OE) configured on 74LV241PW,112?
1OE (pin 1) is active LOW and controls outputs 1Y0–1Y3; 2OE (pin 19) is active HIGH and controls outputs 2Y0–2Y3. This complementary polarity allows independent, glitch-free bus arbitration - for example, holding one group in high-Z while enabling the other for data transfer - without requiring external inverters.
What is the thermal derating behavior of 74LV241PW,112 in its TSSOP20 package?
In the TSSOP20 (SOT360-1) package, the 74LV241PW,112 has a total power dissipation limit of 400 mW at Tamb ≤ 60 °C. Above 60 °C, Ptot derates linearly at 5.5 mW/K - meaning maximum allowable power drops to 345 mW at 70 °C and 235 mW at 90 °C, requiring careful thermal design in enclosed enclosures.
Can 74LV241PW,112 replace 74HC241 or 74HCT241 in existing designs?
Yes - the 74LV241PW,112 is explicitly pin and function compatible with both 74HC241 and 74HCT241. However, due to its lower VCC range (1.0–3.6 V vs. 2.0–6.0 V), it must not be used in 5 V-only systems without verifying input/output voltage margins and timing at the actual operating VCC.
