Product details
Overview
74ABT241PW,112 from Nexperia is an octal 3-state buffer/line driver in TSSOP20 package, designed for high-speed bus interface applications with ±64mA/–32mA output drive, 2.6ns typical propagation delay (tPLH), and dual independent output enables (1OE, 2OE) controlling four outputs each.
For engineers reviewing the 74ABT241PW,112 datasheet, 74ABT241PW,112 pinout, 74ABT241PW,112 application, or 74ABT241PW,112 equivalent, key selection considerations include its 5V operation, latch-up immunity (>500mA), ESD robustness (2000V HBM), and compatibility with TTL/CMOS logic families in industrial control backplanes and memory address buffering.
Technical Context
The 74ABT241PW,112 implements a BiCMOS architecture to achieve low static/dynamic power dissipation while delivering high-speed performance and strong current drive. Its dual 3-state enable structure allows independent control of two 4-bit data paths, supporting bidirectional bus isolation without external logic.
Each output exhibits asymmetric drive strength: –32mA sink at VOH and +64mA source at VOL under specified conditions, enabling robust signal integrity on heavily loaded PCB traces. Inputs remain disabled during 3-state mode, preventing bus contention during enable transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5V to 5.5V - Ensures stable operation across standard 5V supply tolerances in industrial systems. |
| tPLH / tPHL | 2.6ns / 2.7ns (CL = 50pF) - Enables sub-4ns propagation for high-frequency address/data bus timing. |
| IOL / IOH | 64mA / –32mA - Supports direct driving of multiple TTL loads or termination resistors without buffers. |
| CIN / COUT | 3pF / 7pF - Minimizes capacitive loading on upstream drivers and maintains signal edge integrity. |
| ICCZ | 50µA (VCC = 5.5V, outputs disabled) - Reduces quiescent power in standby bus isolation modes. |
| VIH / VIL | 2.0V / 0.8V - Compatible with standard TTL input thresholds for seamless integration into legacy 5V systems. |
Pinout & Package
74ABT241PW,112 uses a 20-pin TSSOP (Thin Shrink Small Outline Package) with 4.4 mm body width (SOT360-1), optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low enables - Independently activate Group 1 (pins 18,16,14,12) or Group 2 (pins 3,5,7,9) outputs. |
| 2,4,6,8 | 1A0–1A3 | Data inputs for Output Group 1 - Drive corresponding 1Yn outputs when 1OE = L. |
| 17,15,13,11 | 2A0–2A3 | Data inputs for Output Group 2 - Drive corresponding 2Yn outputs when 2OE = L. |
| 18,16,14,12 | 1Y0–1Y3 | 3-State outputs (Group 1) - High-impedance state when 1OE = H; driven by 1A0–1A3 otherwise. |
| 3,5,7,9 | 2Y0–2Y3 | 3-State outputs (Group 2) - High-impedance state when 2OE = H; driven by 2A0–2A3 otherwise. |
| 10 | GND | Ground reference - Shared return path for all I/O and supply currents; requires low-impedance PCB plane. |
| 20 | VCC | +5V supply - Must be decoupled locally with 100nF ceramic capacitor near pin 20. |
Key Features
| Feature | Design Value |
|---|---|
| Power-up 3-State | Outputs remain in high-impedance during VCC ramp-up, preventing bus glitches at power-on. |
| Latch-up protection | Exceeds 500mA per JEDEC Std 17 - Ensures reliability in noisy industrial environments with transient coupling. |
| ESD robustness | 2000V HBM, 200V MM - Eliminates need for external ESD protection on board-level I/O lines. |
| Asymmetric output drive | +64mA source / –32mA sink - Optimized for driving pull-down terminated buses and CMOS inputs simultaneously. |
| Input disable in 3-State | Inputs electrically isolated when outputs disabled - Prevents unintended toggling or leakage through unused paths. |

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 SOIC-20 package (SOT163-1); identical AC/DC specs but 7.5mm body width vs. 4.4mm. | Requires PCB footprint change; same thermal profile and routing density constraints. | Select for legacy SOIC assembly lines or where TSSOP reflow compatibility is unverified. |
| 74LVT241PW,118 | Nexperia 3.3V-only variant (VCC = 2.7–3.6V); lower drive (±32mA), faster tPLH (2.1ns), incompatible voltage domain. | Not interchangeable in 5V systems; requires full voltage rail redesign and level shifting. | Choose only for new 3.3V designs prioritizing lower power and higher speed over 5V compatibility. |
Compared with SN74ABT241DBR and 74LVT241PW,118, the 74ABT241PW,112 uniquely balances 5V operation, TSSOP density, and industrial-grade robustness-making it optimal for space-constrained 5V backplane interfaces where pin-for-pin replacement of legacy DIP/SO devices is required without layout revision.

FAQ
What is the operating voltage range for the 74ABT241PW,112?
The 74ABT241PW,112 operates within a recommended DC supply voltage range of 4.5V to 5.5V. This ensures compatibility with standard 5V power rails while accommodating typical tolerance variations. Absolute maximum rating extends to 7.0V, but sustained operation above 5.5V risks reliability degradation. All electrical characteristics-including propagation delay, drive strength, and logic thresholds-are specified and guaranteed only within the 4.5V–5.5V window.
Does the 74ABT241PW,112 support hot insertion or live bus swapping?
Yes, the 74ABT241PW,112 supports controlled hot insertion via its power-up 3-state feature: outputs remain in high-impedance during VCC ramp-up, preventing bus contention. Combined with latch-up immunity exceeding 500mA and 2000V HBM ESD protection, the 74ABT241PW,112 is qualified for use in modular industrial backplanes where cards may be inserted or removed while powered. However, system-level sequencing of VCC and OE signals remains critical for full compliance.
How does the dual output enable (1OE/2OE) function in the 74ABT241PW,112?
The 74ABT241PW,112 features two independent active-low output enables: 1OE controls outputs 1Y0–1Y3 (pins 18,16,14,12), and 2OE controls outputs 2Y0–2Y3 (pins 3,5,7,9). When either enable is high, its associated outputs enter high-impedance state regardless of input states. This allows segmented bus control-for example, isolating upper and lower nibbles of an address bus-without requiring additional gating logic or software overhead.
What is the maximum capacitive load the 74ABT241PW,112 can drive reliably?
The 74ABT241PW,112 is characterized for CL = 50pF in AC specifications, with 2.6ns/2.7ns propagation delays measured under that condition. Its 64mA output drive and low output capacitance (7pF) enable stable operation with loads up to 100pF in most PCB layouts, though timing margins degrade linearly beyond 50pF. For loads >75pF, derating of tPLH/tPHL by ~0.3ns per 10pF is observed; full characterization data is provided in Nexperia's ABT family application note AN10312.
Is the 74ABT241PW,112 pin-compatible with older 74-series logic devices?
The 74ABT241PW,112 is functionally and pin-compatible with industry-standard 74241 octal buffers across all packages (DIP, SO, SSOP, TSSOP), including legacy 74LS241 and 74F241. Pin numbering, signal assignments (1A0–1A3, 1Y0–1Y3, 2A0–2A3, 2Y0–2Y3, 1OE, 2OE, GND, VCC), and logic behavior match the IEEE/IEC standard. No PCB changes are needed when upgrading from those parts, though ABT's superior speed, drive, and robustness deliver immediate system-level benefits.
