Product details
Overview
74LV241D,112 from NXP Semiconductors (formerly Philips) is an octal non-inverting 3-state buffer/line driver in SO20 package, operating from 1.0 V to 3.6 V supply. It features dual independent output-enable controls (1OE active LOW, 2OE active HIGH), 8 ns typical propagation delay at 3.3 V/15 pF, and ±35 mA output drive capability. It serves as a bus interface isolator in low-voltage industrial control backplanes.
For engineers reviewing the 74LV241D,112 datasheet, 74LV241D,112 pinout, 74LV241D,112 application, or 74LV241D,112 equivalent, key selection criteria include its dual OE polarity support, TTL-level input compatibility at VCC ≥ 2.7 V, 3.5 pF input capacitance, −40 °C to +125 °C temperature range, and SO20 thermal derating of 8 mW/K above 70 °C.
Technical Context
The 74LV241D,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. Its Si-gate CMOS process enables rail-to-rail output swing and low static current (≤160 µA at 3.6 V).
Propagation delay is specified down to 1.2 V supply (45 ns typ), with timing parameters fully characterized across −40 °C to +125 °C. Output enable/disable times (tPZH/tPHZ/tPZL/tPLZ) are guaranteed up to 3.6 V, supporting fast bus arbitration in multiplexed data paths.

Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-state control | 1OE (active LOW) and 2OE (active HIGH) allow asymmetric bus arbitration - e.g., one group held active while other responds to dynamic enable signals |
| TTL-input compatibility | Accepts standard TTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) at VCC = 2.7 V to 3.6 V, enabling direct connection to legacy 5 V systems via pull-up resistors |
| Low ground bounce (VOLP) | Typical < 0.8 V at VCC = 3.3 V - reduces noise coupling into shared ground planes during simultaneous switching |
| High-impedance output undershoot control (VOHV) | Typical > 2 V at VCC = 3.3 V - prevents false triggering of downstream receivers during 3-state transitions |
| Wide temperature qualification | Specified from −40 °C to +125 °C with full parameter coverage - eliminates derating assumptions in automotive engine-control units |

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 with identical pinout, same 1.0–3.6 V range, but tPLH/tPHL = 9.5 ns (typ) at 3.3 V/15 pF - 18.75% slower than 74LV241D,112 | Valid for cost-sensitive designs where <1 ns timing margin is acceptable; not recommended for 125 MHz+ buses | Select if TI supply chain preference exists and timing slack ≥1 ns is available in layout |

FAQ
What is the maximum recommended supply voltage for 74LV241D,112?
The absolute maximum supply voltage (VCC) for 74LV241D,112 is +4.6 V per limiting values table, but the recommended operating maximum is 3.6 V. Operation above 3.6 V voids parametric guarantees and risks accelerated aging; sustained use at 4.6 V may cause permanent damage. Always maintain VCC within 1.0 V to 3.6 V for full specification compliance in 74LV241D,112 applications.
Does 74LV241D,112 support true bidirectional data flow?
No, 74LV241D,112 is a unidirectional octal non-inverting buffer - data flows only from A inputs to Y outputs. It lacks internal direction control or bus transceiver architecture. For bidirectional operation, external control logic must manage separate transmit/receive paths; 74LV241D,112 itself cannot auto-sense or reverse signal direction.
How does the dual OE polarity (1OE active LOW, 2OE active HIGH) benefit system design?
The complementary OE polarities in 74LV241D,112 simplify interface with controllers having mixed-active enable outputs - e.g., one microcontroller GPIO can drive 1OE directly (active LOW), while another inverted signal (via single transistor or inverter) drives 2OE (active HIGH). This avoids level-shifting or additional logic gates in 74LV241D,112-based bus isolation schemes.
Can 74LV241D,112 drive a 50 Ω transmission line directly?
Yes, 74LV241D,112 can drive a 50 Ω load with ≤0.4 V VOL at 8 mA sink (VCC = 3.0 V), meeting RS-422 threshold margins. However, for impedance-matched point-to-point links, series termination at the source is recommended to suppress reflections; 74LV241D,112's ±35 mA drive strength supports this without external buffers.
Is 74LV241D,112 pin-compatible with 74HC241 or 74HCT241?
Yes, 74LV241D,112 is explicitly stated as pin and function compatible with 74HC241 and 74HCT241 per its general description. All share identical SO20 pinout, functional behavior, and 3-state control structure. However, voltage ranges differ: HC/HCT require 2 V–6 V, while 74LV241D,112 operates down to 1.0 V, enabling direct drop-in replacement only in 3.3 V or lower systems.
