Product details
Overview
74LVT2241DB,118 from Nexperia is a 3.3 V octal 3-state buffer/line driver with integrated 30 Ω series output termination resistors, dual independent output enables (1OE active LOW, 2OE active HIGH), bus hold inputs eliminating external pull-ups, and ±12 mA drive capability. It operates from 2.7 V to 3.6 V and supports 5 V-tolerant inputs for mixed-voltage system interfacing in high-speed digital backplanes.
For engineers reviewing the 74LVT2241DB,118 datasheet, 74LVT2241DB,118 pinout, 74LVT2241DB,118 application, or 74LVT2241DB,118 equivalent, key selection criteria include its dual 4-bit enable control, on-die 30 Ω series termination, bus hold functionality, -40 °C to +85 °C industrial temperature range, and SO20 (SOT163-1) package compatibility with legacy 74-series footprints.
Technical Context
The device implements two independent 4-bit buffered paths: Group 1 (1A0–1A3 → 1Y0–1Y3, controlled by 1OE) and Group 2 (2A0–2A3 → 2Y0–2Y3, controlled by 2OE). Each output integrates a 30 Ω series resistor to suppress signal reflections without external components.
Bus hold circuitry maintains valid logic states on unused inputs at VI ≤ 0.8 V (LOW) or ≥ 2.0 V (HIGH), with IBHL = 75–150 μA and IBHH = –150 to –75 μA at 3.0 V. IOFF protection enables partial power-down operation when VCC = 0 V, limiting leakage to ±100 μA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.7 V to 3.6 V - Enables direct interface with 3.3 V LVTTL and mixed 5 V/3.3 V systems |
| Output drive | ±12 mA - Sustains robust signal integrity driving 50 Ω transmission lines or multiple TTL loads |
| Propagation delay | 3.0 ns typical (VCC = 3.3 V) - Supports >200 MHz data rates in point-to-point or stubbed bus topologies |

Pinout & Package
74LVT2241DB,118 is supplied in a plastic small outline package (SO20, SOT163-1) with 20 leads and 7.5 mm body width. Pin 1 is index-marked; pins are arranged in dual rows with GND (pin 10) and VCC (pin 20) centrally located for low-inductance decoupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE | Group 1 output enable | Active LOW control for outputs 1Y0–1Y3; enables independent gating of first 4-bit channel |
| 2OE | Group 2 output enable | Active HIGH control for outputs 2Y0–2Y3; allows asynchronous enable/disable of second 4-bit channel |
| 1A0–1A3, 2A0–2A3 | Data inputs | Eight total inputs with bus hold - prevents floating states without external biasing components |
| 1Y0–1Y3, 2Y0–2Y3 | 3-state outputs | Each includes 30 Ω series resistor - eliminates need for external termination on PCB traces |
| VCC (pin 20) | Power supply | 3.3 V nominal supply; accepts 2.7–3.6 V range - compatible with regulated LVTTL rails |
| GND (pin 10) | Ground reference | Common return path for all I/O and internal logic - placed opposite VCC to minimize ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4-bit enables | 1OE (active LOW) and 2OE (active HIGH) allow asymmetric control of two data groups for flexible bus arbitration |
| Integrated 30 Ω series termination | Eliminates four external resistors per group - reduces BOM count and PCB area in high-density routing |
| Bus hold inputs | Maintains defined logic state on unconnected inputs - removes requirement for 10 kΩ pull-up/down resistors |
| 5 V-tolerant inputs | Accepts 0–5.5 V input signals while powered from 3.3 V - enables seamless interfacing with legacy 5 V logic |
| IOFF partial power-down | Leakage < ±100 μA when VCC = 0 V - prevents back-driving of powered buses during hot-swap or power sequencing |
Applications

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 |
|---|---|---|---|
| 74LVT244DB,118 | Single 8-bit enable (OE only); no dual-group control; identical 30 Ω termination and bus hold | Lacks independent 4-bit gating - unsuitable where asymmetric bus arbitration is required | Select when simplified enable logic suffices and cost-per-channel is prioritized |
| SN74LVC244APWR | No integrated termination; 3.3 V only (not 5 V tolerant); lower drive (±24 mA); different pinout | Requires external 30 Ω resistors and pull-ups; incompatible with 5 V input sources | Select only in new 3.3 V-only designs with full layout flexibility for discrete termination |
Compared with 74LVT2241DB,118, the 74LVT244DB,118 offers identical electrical performance but lacks dual-enable flexibility, while SN74LVC244APWR sacrifices 5 V tolerance and integrated termination for higher drive strength-making the 74LVT2241DB,118 optimal for mixed-voltage, space-constrained, high-reliability backplane interfaces.

FAQ
What is the function of the two output enables (1OE and 2OE) on the 74LVT2241DB,118?
1OE is an active-LOW enable controlling outputs 1Y0–1Y3, while 2OE is an active-HIGH enable controlling outputs 2Y0–2Y3. This dual-enable architecture allows independent 4-bit channel control-enabling asymmetric bus arbitration, staggered data latching, or selective isolation of signal groups without affecting the other half of the octal buffer.
Can the 74LVT2241DB,118 safely interface with 5 V logic while operating at 3.3 V supply?
Yes. Its inputs tolerate up to 5.5 V regardless of VCC level, allowing direct connection to 5 V CMOS or TTL outputs. The device maintains valid logic thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and bus hold functionality at 3.3 V supply, enabling robust mixed-voltage interfacing without level shifters or external biasing.
How does the integrated 30 Ω series termination resistor improve signal integrity?
Each output integrates a 30 Ω resistor in series with the driver, matching typical PCB microstrip impedances (45–65 Ω) when combined with trace inductance and load capacitance. This damps ringing and overshoot on unterminated lines up to ~15 cm, eliminating four external resistors per group and reducing layout complexity, parasitic inductance, and potential solder joint failures.
Does the 74LVT2241DB,118 support hot insertion or live board replacement?
Yes. Its IOFF circuitry limits power-off leakage to ±100 μA when VCC = 0 V, preventing back-driving of live buses. Combined with overvoltage-tolerant inputs and robust ESD protection (HBM >2000 V), the device meets requirements for hot-plug-capable systems such as modular telecom chassis and reconfigurable industrial controllers.
