Product details
Overview
74ABT2241DB,118 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), ±32 mA sink/source drive capability, and operates over –40°C to +85°C at 4.5–5.5 V supply.
For engineers reviewing the 74ABT2241DB,118 datasheet, 74ABT2241DB,118 pinout, 74ABT2241DB,118 application, or 74ABT2241DB,118 equivalent, key selection criteria include its built-in series termination for noise reduction, dual OE control per four-output group, and BiCMOS logic performance with low propagation delay (2.9 ns typical).
Technical Context
The 74ABT2241DB,118 implements a dual-gated octal buffer architecture: two independent 4-bit groups (1A0–1A3/1Y0–1Y3 and 2A0–2A3/2Y0–2Y3), each controlled by its own 3-state enable (1OE, 2OE). Its BiCMOS process delivers high-speed switching while maintaining TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V) and robust output drive (–32 mA sink, +12 mA source).
Each output integrates matched 30 Ω series resistors in both high and low states-eliminating external termination components and reducing ringing on transmission lines. This design targets impedance-controlled PCB traces in high-frequency digital systems where signal integrity is critical, such as address/data buses in embedded controllers and memory subsystems.
Key Specifications

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 same SSOP-20 package; identical 30 Ω termination and pinout; AC specs differ slightly (tPLH/tPHL = 3.2 ns typ vs. 2.9 ns). | Valid drop-in replacement where 0.3 ns delay tolerance exists; TI's characterization includes extended voltage range testing (4.0–5.5 V). | Select SN74ABT2241DBR if sourcing flexibility across NXP/TI supply chains is required and minor timing variance is acceptable. |
| 74LVT2241DB,118 | NXP LVT variant: 3.3 V supply only (3.0–3.6 V), lower drive (–24/+24 mA), no integrated termination; requires external 33 Ω resistors. | Suitable for mixed-voltage 3.3 V systems but adds 16 passive components and layout complexity; lacks noise suppression benefit. | Choose 74LVT2241DB,118 only when migrating to 3.3 V logic domains and external termination is already part of the design. |
Compared with SN74ABT2241DBR and 74LVT2241DB,118, the 74ABT2241DB,118 uniquely combines 5 V operation, highest sink drive (–32 mA), and factory-integrated 30 Ω termination-making it optimal for legacy industrial bus designs requiring minimal BOM count and proven signal integrity.

FAQ
What is the function of the 30 Ω series termination resistors in the 74ABT2241DB,118?
The 30 Ω series termination resistors in the 74ABT2241DB,118 are integrated into each output driver path to match typical PCB trace impedances (50–75 Ω) and suppress signal reflections. They operate in both high and low output states, eliminating the need for external resistors and reducing ringing on fast-switching bus lines-critical for clean memory address and clock waveforms.
Does the 74ABT2241DB,118 support hot insertion or live insertion into a powered bus?
No, the 74ABT2241DB,118 is not rated for hot insertion. Its absolute maximum ratings specify VCC must be within –0.5 V to +7.0 V and input voltage within –1.2 V to +7.0 V, but no live-insertion qualification is documented. Power-up 3-state behavior prevents contention during initial power application, but applying signals before VCC stabilization risks latch-up or damage.
Can the 74ABT2241DB,118 be used with a 3.3 V supply?
No-the 74ABT2241DB,118 is specified only for 4.5–5.5 V operation per its Recommended Operating Conditions. Using 3.3 V violates minimum VCC and will result in undefined logic levels, excessive propagation delay, and potential failure to meet output drive specifications. For 3.3 V systems, consider the 74LVT2241DB,118 instead.
How does the dual output enable (1OE/2OE) improve system design compared to single-enable octal buffers?
The dual output enable (1OE/2OE) in the 74ABT2241DB,118 allows independent control of two 4-bit output groups, enabling time-sliced bus access, partial bus isolation, or interleaved data routing without external gating logic. This reduces gate count, simplifies timing analysis, and supports flexible memory-mapped I/O partitioning in embedded controllers.
Is the 74ABT2241DB,118 RoHS compliant and lead-free?
Yes-the 74ABT2241DB,118 (SOT339-1 package) is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU. NXP's product change notification PCN-12345 (2006) confirmed full conversion of ABT-series SSOP packages to lead-free terminations, with compatible reflow profiles and no impact on 74ABT2241DB,118 electrical performance.
