Product details
Overview
74ABT2241PW,112 from NXP Semiconductors (formerly Philips) is an octal 3-state buffer with integrated 30 Ω series output termination resistors, designed for high-speed bus driving in memory address, clock, and bus transceiver applications. It features dual independent output enables (1OE, 2OE), ±12 mA/–32 mA drive capability, and operates over –40°C to +85°C at 4.5–5.5 V.
For engineers reviewing the 74ABT2241PW,112 datasheet, 74ABT2241PW,112 pinout, 74ABT2241PW,112 application, or 74ABT2241PW,112 equivalent, key selection criteria include its built-in series termination for noise reduction, dual OE control per four-output group, and BiCMOS performance balancing speed (2.9 ns typical tPLH), power (50 µA ICCZ), and robustness (500 mA latch-up protection).
Technical Context
The 74ABT2241PW,112 implements a high-performance BiCMOS architecture delivering low static and dynamic power while maintaining TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V) and fast propagation (tPLH/tPHL ≤ 5.3 ns over temperature). Its outputs integrate 30 Ω series resistors in both high and low states-eliminating external termination components on PCBs.
It supports true 3-state operation with power-up 3-state behavior and includes dedicated enable inputs (1OE, 2OE) controlling two independent 4-bit output groups (1Y0–1Y3 and 2Y0–2Y3). Input and output capacitances are tightly specified (CIN = 3 pF, COUT = 7 pF), enabling predictable timing in high-frequency bus environments.
Key Specifications

Pinout & Package
74ABT2241PW,112 is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package), Type I, body width 4.4 mm (SOT360-1), with 0.65 mm lead pitch and surface-mount compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low output enables - Independently disable Group 1 (1Y0–1Y3) or Group 2 (2Y0–2Y3) to manage bus contention. |
| 2, 4, 6, 8 | 1A0–1A3 | Data inputs for first output group - Accept TTL/CMOS logic levels; VIH ≥ 2.0 V ensures noise immunity. |
| 17, 15, 13, 11 | 2A0–2A3 | Data inputs for second output group - Electrically isolated from Group 1; supports dual-bus or multiplexed routing. |
| 18, 16, 14, 12 | 1Y0–1Y3 | 3-state outputs with 30 Ω series termination - Drive terminated lines directly; no external resistor needed. |
| 3, 5, 7, 9 | 2Y0–2Y3 | 3-state outputs with 30 Ω series termination - Matched electrical characteristics to 1Yn outputs for consistent bus behavior. |
| 10 | GND | Signal reference ground - Shared return path for all I/O; requires low-impedance PCB plane for noise control. |
| 20 | VCC | +5 V supply - Powers internal BiCMOS circuitry; decoupling capacitor (0.1 µF) required near pin for AC stability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω series termination | Eliminates eight external resistors per device, reducing BOM count, layout area, and impedance mismatch risk. |

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 |
|---|---|---|---|
| SN74ABT2241DBR | TI version in SSOP-20 (SOT339-1); identical AC/DC specs but slightly higher ICCZ (100 µA max) and no documented 30 Ω series termination. | Lacks integrated termination - requires eight external 30 Ω resistors for equivalent noise suppression. | Select when sourcing TI-qualified parts or when SSOP-20 footprint is preferred over TSSOP-20. |
| 74LVT2241PW,118 | NXP LVT variant: 3.3 V supply only (2.7–3.6 V), lower drive (±12 mA), no integrated 30 Ω resistors, faster tPLH (2.1 ns typ). | Designed for 3.3 V systems; incompatible with 5 V buses unless level-shifted; no built-in termination. | Choose for 3.3 V domains where speed outweighs termination convenience and voltage compatibility is assured. |
Compared with SN74ABT2241DBR and 74LVT2241PW,118, the 74ABT2241PW,112 uniquely delivers 5 V operation with factory-integrated 30 Ω series termination - reducing component count, layout complexity, and signal integrity risk in legacy and mixed-voltage industrial designs.

FAQ
What is the function of the 30 Ω series termination in the 74ABT2241PW,112?
The 30 Ω series termination resistors in the 74ABT2241PW,112 are integrated into each output path (both high and low states) to match typical PCB trace impedances and suppress signal reflections. This eliminates the need for eight external resistors, reduces board space, and improves signal integrity in memory address, clock, and bus applications without requiring layout-level impedance tuning.
Does the 74ABT2241PW,112 support hot insertion or live insertion?
The 74ABT2241PW,112 does not specify hot-insertion capability in its datasheet. While it features power-up 3-state behavior and high latch-up immunity (500 mA), it lacks explicit Ioff (power-off isolation) or live-insertion qualification per JEDEC standards. For hot-swap applications, external protection circuitry or a purpose-built hot-swap controller is recommended alongside the 74ABT2241PW,112.
Can the 74ABT2241PW,112 operate at 3.3 V?
No - the 74ABT2241PW,112 is rated for 4.5 V to 5.5 V operation only. Its input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), output drive strength, and internal BiCMOS structure are optimized for 5 V systems. Operating below 4.5 V risks undefined logic states, reduced noise margins, and failure to meet AC timing specifications. Use 74LVT2241PW,118 for 3.3 V applications.
How are the two output enable pins (1OE and 2OE) used in practice with the 74ABT2241PW,112?
In the 74ABT2241PW,112, 1OE controls outputs 1Y0–1Y3 and 2OE controls outputs 2Y0–2Y3 - enabling independent bus arbitration. For example, in a dual-processor system, one processor can drive Group 1 while the other monitors Group 2, or both groups can be enabled simultaneously for full 8-bit throughput. Each OE is active-low and features guaranteed power-up 3-state behavior.
Is the 74ABT2241PW,112 pin-compatible with standard 74-series octal buffers like the 74LS241?
No - the 74ABT2241PW,112 has a unique pinout optimized for dual-group control and integrated termination. Unlike the 74LS241 (which uses a single OE and different pin mapping), the 74ABT2241PW,112 places 1OE at pin 1, 2OE at pin 19, and interleaves inputs/outputs to minimize crosstalk. Direct replacement would require PCB redesign; it is not a drop-in substitute for legacy 74LS or 74HC variants.
