Product details
Overview
74ABT2241D,118 from NXP Semiconductors (formerly Philips) is an octal 3-state buffer with integrated 30Ω series output termination resistors, designed for high-speed bus driving in memory address, clock, and data bus applications. It features dual independent output enables (1OE, 2OE), ±32mA/±12mA output drive, and operates over –40°C to +85°C at 4.5–5.5V supply.
For engineers reviewing the 74ABT2241D,118 datasheet, 74ABT2241D,118 pinout, 74ABT2241D,118 application, or 74ABT2241D,118 equivalent, key selection criteria include its built-in series termination for noise reduction, dual OE control per four-channel group, and BiCMOS performance balancing speed (2.9ns typical tPLH), low capacitance (3pF CIN), and latch-up immunity (>500mA).
Technical Context
The 74ABT2241D,118 implements a high-performance BiCMOS architecture delivering low static/dynamic power with high-speed switching. Its outputs integrate matched 30Ω series resistors in both high and low states-eliminating external termination components and reducing ringing on transmission lines.
It provides two independent 3-state control paths: 1OE governs outputs 1Y0–1Y3, and 2OE governs 2Y0–2Y3. Power-up 3-state behavior ensures outputs remain high-impedance during VCC ramp-up, preventing bus contention at startup.

Pinout & Package
74ABT2241D,118 is supplied in a 20-pin plastic SO (Small Outline) package per SOT163-1, 7.5 mm body width, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low output enable controls for two independent 4-bit groups - allows selective bus isolation without global reset. |
| 2,4,6,8 | 1A0–1A3 | Data inputs for first output group - routed to 1Y0–1Y3 when 1OE is low. |
| 17,15,13,11 | 2A0–2A3 | Data inputs for second output group - routed to 2Y0–2Y3 when 2OE is low. |
| 18,16,14,12 | 1Y0–1Y3 | 3-state outputs with integrated 30Ω series termination - drive bus lines directly with controlled impedance. |
| 3,5,7,9 | 2Y0–2Y3 | 3-state outputs with integrated 30Ω series termination - operate independently of first group for split-bus architectures. |
| 10 | GND | Ground reference - shared return path for all I/O and internal logic; requires low-inductance PCB connection. |
| 20 | VCC | Positive supply - must be decoupled locally (e.g., 100nF ceramic) to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30Ω series termination | Eliminates need for eight discrete 30Ω resistors - reduces BOM count, PCB area, and layout complexity for bus drivers. |
| Dual independent 3-state enables | Enables partial bus gating - e.g., isolate memory address vs. data lanes without disabling entire interface. |
| Power-up 3-state | Guarantees high-impedance outputs during power ramp - prevents bus contention and data corruption at system boot. |
| BiCMOS process technology | Combines CMOS input stage (low leakage, high noise margin) with bipolar output stage (high drive, fast edges) for optimal speed-power tradeoff. |
| Latch-up immunity >500mA | Exceeds JEDEC Std 17 - ensures robustness against transient current surges in noisy industrial environments. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT2241DBR | TI version in SSOP-20 (SOT339-1); identical AC/DC specs but different thermal resistance and moisture sensitivity level (MSL 3 vs MSL 1 for 74ABT2241D,118). | Same functional replacement for space-constrained layouts requiring 5.3mm body width instead of 7.5mm SO. | Select when board real estate is limited and SSOP reflow profile is validated. |
| 74LVT2241PW,118 | NXP LVT variant in TSSOP-20 (SOT360-1); lower VCC range (2.7–3.6V), no integrated 30Ω termination, higher speed (2.3ns tPLH), and 3.3V-only compatibility. | Not suitable for 5V systems or termination-critical designs; intended for low-voltage, high-density 3.3V buses. | Choose only for 3.3V-only applications where external termination is acceptable and smaller footprint is mandatory. |

FAQ
What is the function of the 30Ω series termination in the 74ABT2241D,118?
The 30Ω series termination resistors in the 74ABT2241D,118 are integrated into each output driver path to match typical PCB trace impedance and suppress signal reflections. This eliminates the need for eight external resistors, reduces EMI, and improves edge fidelity on memory address, clock, and data buses - especially in stubbed or unterminated topologies.
Does the 74ABT2241D,118 support hot insertion or live insertion into a powered bus?
No - the 74ABT2241D,118 is not hot-swap rated. While it features power-up 3-state behavior and high latch-up immunity (>500mA), its absolute maximum ratings do not guarantee safe operation during live insertion. Bus isolation must be managed externally via sequencing or dedicated hot-swap controllers before introducing the 74ABT2241D,118 into an active system.
Can both output enable pins (1OE and 2OE) be tied together for single-enable operation?
Yes - 1OE and 2OE can be connected to a common control signal. Doing so synchronously enables or disables all eight outputs, effectively converting the 74ABT2241D,118 into a standard octal buffer. However, this forfeits the benefit of independent group control, which is essential for partial bus isolation in complex memory or peripheral interfaces.
What is the maximum capacitive load the 74ABT2241D,118 can drive while maintaining specified propagation delay?
The 74ABT2241D,118 is characterized at CL = 50pF for tPLH/tPHL = 2.9ns (typical). Driving loads beyond 50pF increases propagation delay nonlinearly and may degrade edge rate. For loads >75pF, derating analysis or empirical validation is required - the 30Ω series termination helps but does not eliminate delay degradation under heavy capacitive loading.
Is the 74ABT2241D,118 RoHS compliant and lead-free?
Yes - the 74ABT2241D,118 is manufactured in compliance with RoHS Directive 2011/65/EU and is lead-free. The SOT163-1 package uses matte tin (Sn) lead finish, and the device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 - indicating unlimited floor life at ≤30°C/60% RH.
