Product details

Overview

74LVC241ADB,112 from NXP Semiconductors is an octal non-inverting 3-state buffer/line driver in SSOP20 package, operating from 1.2 V to 3.6 V supply, with 5 V tolerant inputs and outputs, Schmitt-trigger inputs for noise immunity, and −40 °C to +125 °C temperature range. It enables bidirectional voltage translation between 3.3 V and 5 V logic domains in bus interface applications.

For engineers reviewing the 74LVC241ADB,112 datasheet, 74LVC241ADB,112 pinout, 74LVC241ADB,112 application, or 74LVC241ADB,112 equivalent, key selection criteria include 5 V tolerance on all I/O pins, dual active-Low/active-High output enable control (1OE/2OE), propagation delay ≤7.1 ns at 3.3 V, and compliance with JEDEC JESD8-7A/5A/C standards for low-voltage operation.

Technical Context

The 74LVC241ADB,112 implements two independent 4-bit non-inverting buffer groups (1A0–1A3 → 1Y0–1Y3 and 2A0–2A3 → 2Y0–2Y3), each controlled by separate output enable signals: 1OE (active LOW) and 2OE (active HIGH). Its Schmitt-trigger input structure ensures robust operation with slow-rising/falling waveforms and eliminates input noise-induced glitches.

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 when disabled. The device maintains high-impedance state when VCC = 0 V, enabling safe hot-insertion and power sequencing in multi-rail systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	1.2 V to 3.6 V - Enables direct integration into 1.8 V, 2.5 V, and 3.3 V logic systems without level-shifting circuitry.
I/O voltage tolerance	0 V to 5.5 V - Allows connection to legacy 5 V peripherals while powered from lower-voltage rails, eliminating external translators.
Propagation delay	≤7.1 ns at VCC = 3.0–3.6 V - Supports high-speed data transfer across local buses (e.g., address/data latching) with minimal timing skew.
Output drive strength	±24 mA at VCC = 3.0 V - Sufficient to drive 15 pF loads with <10 ns rise/fall times, meeting TTL-compatible fan-out requirements.
Operating temperature	−40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC backplanes, and extended-temperature embedded controllers.
ESD protection	HBM >2000 V, CDM >1000 V - Robust handling during PCB assembly and field service without additional protection components.
Input hysteresis	Schmitt-trigger action - Rejects noise on slow edges (e.g., mechanical switch debouncing, long trace signals) without external RC filtering.

Pinout & Package

74LVC241ADB,112 is housed in a plastic shrink small outline package (SSOP20) with 20 leads, body width 5.3 mm (SOT339-1), optimized for high-density PCB layouts and automated surface-mount assembly.

Pin/Terminal	Circuit Role	Design Meaning
1	1OE	Active-LOW output enable for Group 1 (1A0–1A3 → 1Y0–1Y3); asserts high-impedance on 1Yn when HIGH.
2, 4, 6, 8	1A0–1A3	Data inputs for Group 1; accept 0–5.5 V regardless of VCC, with Schmitt-trigger thresholds.
10	GND	Ground reference (0 V) for all internal logic and I/O circuits; must be low-impedance for noise immunity.
12, 14, 16, 18	1Y0–1Y3	Non-inverting buffered outputs for Group 1; drive 3.3 V or 5 V loads with ±24 mA capability.
11, 13, 15, 17	2A0–2A3	Data inputs for Group 2; electrically identical to 1A[0:3], supporting independent signal routing.
3, 5, 7, 9	2Y0–2Y3	Non-inverting buffered outputs for Group 2; enabled by 2OE (pin 19, active HIGH).
19	2OE	Active-HIGH output enable for Group 2; places 2Yn in high-Z when LOW.
20	VCC	Positive supply (1.2–3.6 V); powers internal logic and output drivers; decoupling capacitor required near pin.

Key Features

Feature	Design Value
Dual independent 4-bit buffers	Enables simultaneous but isolated data path control-e.g., one group for address lines, another for control signals-without cross-talk.
5 V tolerant I/O at any VCC	Eliminates need for discrete level shifters when interfacing 5 V sensors or legacy peripherals to modern low-voltage MCUs.
Two asymmetric output enables	1OE (active LOW) and 2OE (active HIGH) allow direct connection to complementary control signals (e.g., /CS and CS) without inverters.
Power-off high-impedance	Outputs remain in high-Z even when VCC = 0 V, preventing back-driving of powered subsystems during partial power-down sequences.
JEDEC-compliant low-voltage operation	Fully specified per JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), ensuring interoperability across voltage bins.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC241APWRE4	TSSOP20 package (4.4 mm width); identical electrical specs and pinout; slightly higher dynamic power dissipation (CPD = 21.0 pF vs. 20.5 pF at 3.3 V).	Better suited for ultra-high-density layouts where board space is constrained; thermal derating starts at 60 °C (vs. 60 °C for SSOP).	Select when footprint size is prioritized over thermal margin; verify PCB land pattern compatibility with SOT360-1.
74LVC241AD,118	SO20 package (7.5 mm width); same electrical performance; higher thermal resistance (Ptot derates at 8 mW/K above 70 °C vs. 5.5 mW/K above 60 °C for SSOP).	Preferred for through-hole prototyping or legacy SOIC footprints; less suitable for high-power-density industrial modules.	Choose for manual assembly, rework-friendly designs, or compatibility with existing SO20-referenced schematics.

Compared with SN74LVC241APWRE4 and 74LVC241AD,118, the 74LVC241ADB,112 offers optimal balance of compact SSOP20 footprint, thermal performance at elevated ambient temperatures, and proven reliability in automotive-grade production environments-making it ideal for space-constrained, thermally demanding applications.

FAQ

What is the maximum input voltage the 74LVC241ADB,112 can tolerate on its I/O pins?

The 74LVC241ADB,112 supports input voltages from −0.5 V to +5.5 V on all I/O pins, regardless of VCC level (1.2 V to 3.6 V). This 5 V tolerance allows direct connection to legacy 5 V logic without external level shifters, and is validated per JEDEC JESD8-C and JESD36 standards for 2.7–3.6 V operation.

Does the 74LVC241ADB,112 support hot-swap or power sequencing scenarios?

Yes-the 74LVC241ADB,112 features power-off high-impedance behavior: when VCC = 0 V, outputs remain in high-Z state with IOFF ≤20 µA at 5.5 V applied. This prevents back-driving of live buses during partial power-up/down sequences, making it suitable for hot-plug applications like modular test fixtures and field-replaceable units.

How does the Schmitt-trigger input on the 74LVC241ADB,112 improve system reliability?

The Schmitt-trigger input on each pin of the 74LVC241ADB,112 provides hysteresis (typically 0.3–0.5 V), rejecting noise and slow edge rates (<20 ns/V at 3.3 V). This eliminates false triggering from EMI, crosstalk, or mechanical switch bounce-critical in industrial control panels and automotive harnesses where signal integrity is compromised.

Can the 74LVC241ADB,112 drive standard TTL loads directly?

Yes-the 74LVC241ADB,112 delivers ±24 mA output drive at VCC = 3.0 V, exceeding the ±0.4 mA requirement for standard TTL inputs. Its VOH ≥2.2 V and VOL ≤0.4 V at 4 mA load meet TTL voltage thresholds, enabling direct interface without pull-up resistors or buffer amplification.

What is the thermal derating behavior of the 74LVC241ADB,112 in SSOP20 package?

For the 74LVC241ADB,112 in SSOP20 (SOT339-1), total power dissipation (Ptot) derates linearly at 5.5 mW/K above +60 °C. At +125 °C ambient, maximum allowable Ptot drops to ~150 mW from the rated 500 mW at +25 °C-requiring careful thermal design in enclosed industrial enclosures or under-hood automotive modules.
