Product details
Overview
74LVT241PW,112 from Nexperia is a 3.3 V octal 3-state buffer/line driver in TSSOP20 package, featuring dual independent output enables (1OE active LOW, 2OE active HIGH), ±32 mA/±64 mA drive capability, bus-hold inputs, and operation from –40 °C to +85 °C. It interfaces 3.3 V logic with 5 V buses and drives high-capacitance backplanes or memory address/data lines in industrial control and telecom infrastructure.
For engineers reviewing the 74LVT241PW,112 datasheet, 74LVT241PW,112 pinout, 74LVT241PW,112 application, or 74LVT241PW,112 equivalent, key selection criteria include dual 3-state control timing, bus-hold input retention without external resistors, TTL-compatible switching levels, and verified 3.3 V supply operation with 5 V-tolerant I/O.
Technical Context
This BiCMOS octal buffer implements two independent 4-bit 3-state output groups-Group 1 (1A0–1A3 → 1Y0–1Y3, controlled by 1OE) and Group 2 (2A0–2A3 → 2Y0–2Y3, controlled by 2OE). Each group supports simultaneous enable/disable with distinct polarity: 1OE is active LOW, 2OE is active HIGH.
Bus-hold circuitry maintains valid logic states on unused inputs at VI = 0.8 V (LOW) or 2.0 V (HIGH), eliminating pull-up/pull-down requirements. Propagation delays are specified at 1.0–3.8 ns (tPLH/tPHL) and 1.0–5.2 ns (3-state transition times) under 3.3 V ±0.3 V supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.6 V - ensures stable operation across industrial voltage tolerances and brown-out margins |
| Output Drive | +64 mA / –32 mA - supports driving 50 pF loads at >10 MHz while maintaining VOL ≤ 0.55 V and VOH ≥ 2.0 V |
| Propagation Delay | 1.0–3.8 ns (tPLH/tPHL) - enables sub-4 ns signal routing for high-speed bus interfacing |

| Input Voltage Range | 0 V to 5.5 V - allows direct connection to 5 V TTL systems without level-shifting circuitry |
| Operating Temperature | –40 °C to +85 °C - qualified for extended industrial ambient environments |
| Bus-Hold Current | ±75 μA to ±150 μA - actively retains logic state on floating inputs, reducing BOM count and board space |

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 |
|---|---|---|---|
| SN74LVC241APWR | Lower drive (+24 mA/–24 mA), 1.65–3.6 V supply, single active-LOW OE | Limited to low-capacitance loads (<30 pF); unsuitable for 5 V bus driving | Select when power budget is constrained and only one enable group is needed |
| 74ALVCH162244DGG | 16-bit, dual 8-bit groups, 1.65–3.6 V, higher ICC (0.4 mA typ), no bus-hold | Requires external pull-ups; larger footprint (TSSOP48); higher static current | Select for wider bus widths where per-pin cost and layout density outweigh bus-hold benefit |
Compared with SN74LVC241APWR and 74ALVCH162244DGG, the 74LVT241PW,112 uniquely combines dual-polarity OE control, 5 V-tolerant I/O, bus-hold, and ±64 mA drive-making it optimal for robust, mixed-voltage industrial bus interfacing where reliability and signal integrity are prioritized over minimal quiescent current.

FAQ
What is the maximum capacitive load the 74LVT241PW,112 can drive while maintaining specified timing?
The device is characterized up to 50 pF load capacitance at 10 MHz with tPLH/tPHL ≤ 3.8 ns (VCC = 3.3 V). Driving >50 pF increases propagation delay nonlinearly and may exceed VOL/VOH limits at full drive current; use series termination or reduce slew rate if exceeding this value.
Can 74LVT241PW,112 safely interface with a 5 V microcontroller's GPIO without level shifters?
Yes-the inputs tolerate 0–5.5 V and maintain TTL-compatible thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and outputs drive 5 V buses directly. However, ensure VCC remains within 2.7–3.6 V; do not apply 5 V to VCC.
How does bus-hold functionality behave when an input is left unconnected during power-up?
Bus-hold circuitry actively pulls unconnected inputs to the last valid logic state (HIGH or LOW) with ±75 μA to ±150 μA current, preventing metastability. No external resistors are needed, and the feature operates across the full –40 °C to +85 °C range.
Is the 74LVT241PW,112 pin-compatible with other packages of the same part number?
Yes-74LVT241PW (TSSOP20), 74LVT241D (SO20), and 74LVT241BQ (DHVQFN20) share identical pin functions and electrical specifications. Only mechanical dimensions, thermal performance, and soldering requirements differ; PCB layout must match the selected package outline (SOT360-1).
