Product details
Overview
74ABT241PW,118 from Nexperia is an octal 3-state buffer/line driver in TSSOP20 package, designed for bidirectional bus interfacing with ±64mA/–32mA output drive, 2.6ns typical propagation delay (An to Yn), and power-up 3-state functionality. It supports industrial temperature range (–40°C to +85°C) and is used in address/data bus driving applications in embedded controllers and peripheral interfaces.
For engineers reviewing the 74ABT241PW,118 datasheet, 74ABT241PW,118 pinout, 74ABT241PW,118 application, or 74ABT241PW,118 equivalent, key selection criteria include dual independent output enables (1OE/2OE), high-current sink capability, input disable during 3-state mode, and compatibility with 5V TTL logic systems.
Technical Context
The 74ABT241PW,118 implements a BiCMOS architecture delivering low static/dynamic power with high-speed performance. It features two independent 3-state control inputs (1OE and 2OE), each enabling four outputs - 1Y0–1Y3 and 2Y0–2Y3 - while inputs (1A0–1A3, 2A0–2A3) remain active only when their respective OE is asserted low.
Its logic behavior follows standard IEEE/IEC truth table: outputs go high-impedance (Z) when OE = H, and replicate inputs when OE = L. Input clamping (–0.9V min) and ESD protection (>2000 V HBM) ensure robustness in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - ensures reliable operation across standard 5V TTL supply tolerances. |
| tPLH / tPHL | 2.6 ns / 2.7 ns (CL = 50 pF, VCC = 5 V) - enables sub-400 MHz bus timing margins in high-speed digital systems. |
| IOL / IOH | 64 mA / –32 mA - supports direct driving of heavy capacitive loads or multiple TTL inputs without external buffers. |
| CIN / COUT | 3 pF / 7 pF - minimizes switching noise and reduces dynamic power consumption on data buses. |
| ICCZ | 50 µA (VCC = 5.5 V, outputs disabled) - maintains ultra-low quiescent current during 3-state hold conditions. |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade reliability in non-automotive embedded applications. |
Pinout & Package
74ABT241PW,118 is housed in a 20-pin plastic thin shrink small outline package (TSSOP20, SOT360-1), 4.4 mm body width, lead pitch 0.65 mm, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low enables controlling separate 4-bit output groups; allows partial bus isolation without full device disable. |
| 2, 4, 6, 8 | 1A0–1A3 | First group of data inputs feeding outputs 1Y0–1Y3 when 1OE = L. |
| 17, 15, 13, 11 | 2A0–2A3 | Second group of data inputs feeding outputs 2Y0–2Y3 when 2OE = L. |
| 18, 16, 14, 12 | 1Y0–1Y3 | 3-state outputs driven by 1A0–1A3; high-impedance when 1OE = H. |
| 3, 5, 7, 9 | 2Y0–2Y3 | 3-state outputs driven by 2A0–2A3; high-impedance when 2OE = H. |
| 10 | GND | Reference ground for all I/O and internal circuitry; must be low-impedance connection. |
| 20 | VCC | Primary 5V supply rail; decoupling capacitor required near pin for AC noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Power-up 3-State | Outputs remain in high-impedance state during power ramp-up, preventing bus contention at system startup. |
| Latch-up immunity | Exceeds 500 mA per JEDEC Std 17 - eliminates risk of destructive latch-up under transient overvoltage events. |
| Input disable in 3-State | Inputs are electrically isolated from internal logic when outputs are disabled, reducing dynamic power and crosstalk. |
| High-current sink | 64 mA output sink capability enables direct interface with LEDs, relays, or legacy TTL loads without external drivers. |
Applications
| Industrial PLC Backplane Interface | Embedded Microcontroller Bus Expansion |

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 |
|---|---|---|---|
| SN74ABT241DBR | TI version in SSOP20 (SOT339-1); identical AC/DC specs but different thermal resistance (θJA = 120°C/W vs. 145°C/W for Nexperia). | Same functional replacement; slightly better thermal performance in high-density PCB layouts. | Select SN74ABT241DBR if board layout allows SSOP20 footprint and thermal margin is constrained. |
| 74LVT241PW,118 | Nexperia's 3.3V variant (VCC = 2.7–3.6 V); lower drive (±32mA), faster tPLH (1.9 ns), incompatible voltage domain. | Not interchangeable - requires level translation when interfacing with 5V systems. | Choose 74LVT241PW,118 only for new 3.3V-only designs where power efficiency and speed outweigh voltage compatibility. |
Compared with SN74ABT241DBR and 74LVT241PW,118, the 74ABT241PW,118 uniquely balances 5V TTL compatibility, industrial temperature range, and high sink current - making it optimal for legacy bus upgrades and mixed-voltage industrial backplanes where drop-in replacement and proven reliability are mandatory.

FAQ
What is the recommended operating voltage range for the 74ABT241PW,118?
The 74ABT241PW,118 is specified for DC supply voltage (VCC) from 4.5 V to 5.5 V at ambient temperatures from –40°C to +85°C. Operation outside this range may cause unreliable logic behavior or permanent damage. The 74ABT241PW,118 draws only 50 µA in 3-state quiescent mode at VCC = 5.5 V, supporting low-power system design within its rated window.
Does the 74ABT241PW,118 support hot insertion or live bus swapping?
The 74ABT241PW,118 includes power-up 3-state functionality and input disable during 3-state mode, which prevent bus contention during power sequencing - but it lacks explicit hot-swap protection circuitry such as slew-rate control or back-drive immunity. While widely used in field-upgradeable systems, the 74ABT241PW,118 should be deployed with external current-limiting resistors or sequenced enable control for true hot-plug operation.
How many independent output groups does the 74ABT241PW,118 support?
The 74ABT241PW,118 supports two independent 4-bit output groups: outputs 1Y0–1Y3 are controlled by 1OE, and outputs 2Y0–2Y3 are controlled by 2OE. This dual-enable architecture allows selective bus segmentation - for example, enabling address lines while holding data lines in high-impedance - a feature confirmed in the function table and pin description of the 74ABT241PW,118 datasheet.
What is the maximum output sink current rating for the 74ABT241PW,118?
The 74ABT241PW,118 is rated for 64 mA DC output sink current per pin (IOL) under recommended operating conditions (VCC = 4.5 V, Tamb = –40°C to +85°C). This value is verified in the DC Electrical Characteristics table and enables direct driving of multiple TTL loads or moderate-current peripherals without external buffering - a key specification distinguishing the 74ABT241PW,118 from standard LS or LVC variants.
Is the 74ABT241PW,118 pin-compatible with older 74-series logic devices?
Yes - the 74ABT241PW,118 maintains identical pinout and logic function to industry-standard 74241 devices including 74LS241 and 74F241, as confirmed by the PIN CONFIGURATION diagram and FUNCTION TABLE in its datasheet. However, due to higher drive strength and faster propagation, layout parasitics must be reviewed to avoid ringing or ground bounce not present in slower predecessors - the 74ABT241PW,118 requires careful PCB routing despite mechanical and logical compatibility.
