Product details
Overview
74LVT241D,112 from Nexperia is a 3.3 V BiCMOS octal 3-state buffer/line driver with dual independent output enables (1OE active LOW, 2OE active HIGH), ±64 mA/–32 mA drive capability, bus-hold inputs, and operation from –40 °C to +85 °C. It interfaces 3.3 V logic to 5 V buses and drives high-capacitance backplanes or memory address/data lines in industrial control and telecom infrastructure.
For engineers reviewing the 74LVT241D,112 datasheet, 74LVT241D,112 pinout, 74LVT241D,112 application, or 74LVT241D,112 equivalent, key selection criteria include its dual OE architecture for segmented bus control, TTL-compatible input thresholds, 2.8 ns typical propagation delay at 3.3 V, bus-hold functionality eliminating external pull-ups, and SO20 (SOT163-1) package compatibility with legacy 20-pin layouts.
Technical Context
This device implements two independent 4-bit 3-state buffers in a single SO20 package: Group 1 (1A0–1A3 → 1Y0–1Y3, controlled by 1OE) and Group 2 (2A0–2A3 → 2Y0–2Y3, controlled by 2OE). Each group supports bidirectional voltage-level translation between 3.3 V logic domains and 5 V bus environments without level shifters.
The BiCMOS process delivers low static current (0.12 mA typical ICC with outputs disabled) while sustaining fast switching (3.8 ns max tPLH/tPHL at 3.3 V) and robust ESD protection (2000 V HBM, 1000 V CDM). Bus-hold circuitry maintains valid logic states on unused inputs, reducing board space and BOM count.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.7 V to 3.6 V - Ensures stable operation across industrial-grade 3.3 V rails with ±0.3 V tolerance. |
| Output drive | +64 mA / –32 mA - Drives heavy capacitive loads (e.g., >50 pF traces) and multiple TTL inputs without signal degradation. |
| Propagation delay | 2.8 ns typical (tPLH/tPHL @ 3.3 V) - Enables reliable timing in sub-300 MHz bus systems with margin for trace skew. |
| Input threshold | VIL ≤ 0.8 V, VIH ≥ 2.0 V - Fully compatible with TTL logic families and 5 V microcontroller I/O without level conversion. |
| Bus-hold current | ±75 μA to ±150 μA - Actively retains logic state on floating inputs, removing need for 10 kΩ pull-up/down resistors per unused pin. |
| ESD rating | HBM >2000 V, CDM >1000 V - Survives handling and board assembly without special ESD controls beyond standard practices. |
| Operating temperature | –40 °C to +85 °C - Qualified for extended-temperature industrial applications including base station control cards and PLC modules. |
Pinout & Package
74LVT241D,112 uses the SO20 plastic small outline package (SOT163-1), 7.5 mm body width, 20 leads, gull-wing leads, and standard 1.27 mm pitch. Pin 1 is marked by a beveled corner or index notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-LOW enable for outputs 1Y0–1Y3; asserts 3-state when HIGH, enables drive when LOW. |
| 2 | VCC | 3.3 V supply input; decoupling capacitor (100 nF) required within 5 mm of this pin. |
| 3–4,6,8 | 1A0–1A3 | Data inputs for first buffer group; accept TTL/CMOS levels and feature bus-hold. |
| 5,7,9,11 | 2Y0–2Y3 | Outputs for second buffer group; sink up to 64 mA or source up to 32 mA. |
| 10 | GND | 0 V reference; must connect to solid ground plane under package for noise immunity. |
| 12–14,16,18 | 1Y0–1Y3 | Outputs for first buffer group; electrically isolated from 2Yn outputs when respective OE is inactive. |
| 13,15,17,19 | 2A0–2A3 | Data inputs for second buffer group; identical electrical behavior to 1An pins. |
| 20 | VCC | Redundant supply connection; ties to same 3.3 V rail as Pin 2 for improved power integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-state control | Separate 1OE (active LOW) and 2OE (active HIGH) allow asymmetric bus partitioning - e.g., one group enabled during read, the other during write cycles. |
| Bus-hold inputs | Eliminates external pull-up/pull-down resistors on all 8 data inputs, reducing PCB area by ~16 mm² and BOM line items by 8 components. |
| 5 V-tolerant inputs | Accepts 0 V to 5.5 V input signals while powered from 3.3 V, enabling direct interface to legacy 5 V peripherals without translators. |
| Live insertion/extraction support | Power-up 3-state and Ioff < ±100 μA prevent bus contention during hot-swap operations in modular backplane systems. |
| Latch-up immunity | JESD78 Class II Level A (>500 mA) ensures survival during transient overvoltage events common in industrial I/O modules. |
Applications
| Industrial PLC Backplane Interface | Telecom Line Card Address Buffer |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC244APWR | Single OE (active LOW), 24 mA drive, no bus-hold, 1.65–3.6 V supply | Requires external pull-ups on unused inputs; lower drive limits use in high-capacitance routing | Select when cost sensitivity outweighs bus-hold convenience and drive requirements are ≤24 mA. |
| 74ALVCH162244DL | 16-bit, dual OE, 24 mA drive, bus-hold, 1.65–3.6 V supply, TSSOP48 | Higher pin count and wider package; not drop-in compatible with SO20 footprint | Choose for higher channel density where board space permits larger package and additional buffering is needed. |
Compared with SN74LVC244APWR and 74ALVCH162244DL, the 74LVT241D,112 uniquely combines dual OE control, 64 mA sink capability, and integrated bus-hold in a legacy-compatible SO20 package-making it optimal for retrofitting 5 V bus interfaces without redesigning layout or adding discrete biasing components.

FAQ
Can 74LVT241D,112 safely drive a 5 V bus while powered from 3.3 V?
Yes. Its inputs tolerate 0 V to 5.5 V regardless of VCC, and outputs swing rail-to-rail (0 V to 3.3 V) while sinking up to 64 mA into a 5 V bus via external pull-ups. This configuration is explicitly validated in Nexperia's application guidance for mixed-voltage bus interfacing.
What is the function of the exposed thermal pad on the DHVQFN20 variant, and does the SO20 version have one?
The SO20 package (74LVT241D) has no thermal pad; it relies on lead-frame conduction. The DHVQFN20 variant (74LVT241BQ) includes an exposed die paddle that must remain electrically floating or tied to GND - but this pad is absent in the SO20 form factor used by 74LVT241D,112.
How does bus-hold eliminate external resistors, and what is its effective hold strength?
Bus-hold circuitry provides active feedback maintaining the last-valid logic state on unused inputs. At 3.0 V VCC, it sources/sinks 75–150 μA to counteract leakage or noise, equivalent to a ~20 kΩ pull-up/down - sufficient to override typical PCB leakage (<1 μA) without discrete components.
Is 74LVT241D,112 qualified for automotive applications?
No. Nexperia explicitly states this device is non-automotive qualified. It lacks AEC-Q100 stress testing, automotive-grade screening, and guaranteed PPAP documentation. Use only in industrial, telecom, or commercial systems where automotive qualification is not mandated.
