Product details
Overview
74ABT241D,623 from Nexperia is an octal 3-state buffer/line driver in a 20-pin SO package, designed for bidirectional bus interfacing with ±64mA/–32mA output drive, 2.6ns typical propagation delay (tPLH), and operation across –40°C to +85°C. It features dual independent output enables (1OE, 2OE), each controlling four outputs, and is used in industrial control backplanes and memory address/data bus drivers.
For engineers reviewing the 74ABT241D,623 datasheet, 74ABT241D,623 pinout, 74ABT241D,623 application, or 74ABT241D,623 equivalent, key selection criteria include 5V supply compatibility, high-current 3-state output capability, dual enable control architecture, and SO20 thermal and layout characteristics for dense PCB designs.
Technical Context
The 74ABT241D,623 implements a BiCMOS octal buffer with two independent 4-bit 3-state output groups, each controlled by dedicated OE pins (1OE on pin 1, 2OE on pin 19). Its logic function follows IEEE/IEC standard truth table with high-impedance (Z) state activated when either OE is high.
It operates within 4.5V–5.5V VCC, supports input voltages from 0V to VCC, and guarantees VIH ≥ 2.0V and VIL ≤ 0.8V at 5V. Output disable times (tPHZ/tPLZ) are specified up to 7.1ns max over temperature, and power-up 3-state behavior prevents bus contention during power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5V to 5.5V - Ensures stable operation under industrial 5V rail tolerances without regulation overhead. |
| tPLH / tPHL | 2.6ns / 2.7ns typ @ CL=50pF - Enables sub-4ns edge-to-edge timing for 250+ MHz bus cycles. |
| IOL / IOH | 64mA sink / –32mA source - Drives heavy capacitive loads (e.g., >10 TTL inputs or long traces) without external buffers. |
| CIN / COUT | 3pF / 7pF - Minimizes switching noise and dynamic power in high-speed parallel interfaces. |
| ICCZ | 50µA max @ VCC=5.5V - Ultra-low quiescent current in 3-state mode reduces system standby power. |
| Operating Temp | –40°C to +85°C - Qualified for extended industrial ambient environments without derating. |
Pinout & Package
74ABT241D,623 is supplied in a 20-pin plastic small outline package (SO20, SOT163-1), 7.5 mm body width, with standard JEDEC MO-153 footprint and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low output enables - Independently disable Group 1 (pins 18,16,14,12) or Group 2 (pins 3,5,7,9) to isolate bus segments. |
| 2,4,6,8 | 1A0–1A3 | Data inputs for Group 1 outputs - Accept TTL/CMOS logic levels; latch-up protected per JEDEC Std 17. |
| 17,15,13,11 | 2A0–2A3 | Data inputs for Group 2 outputs - Electrically isolated from Group 1; supports independent data paths. |
| 18,16,14,12 | 1Y0–1Y3 | 3-state outputs for Group 1 - High-drive (64mA sink) outputs with fast disable (≤7.1ns) for clean bus release. |
| 3,5,7,9 | 2Y0–2Y3 | 3-state outputs for Group 2 - Matched timing and drive strength to Group 1; enables symmetrical bus loading. |
| 10 | GND | Digital ground reference - Shared return path for all I/O; requires low-inductance connection to minimize ground bounce. |
| 20 | VCC | +5V supply - Must be decoupled locally (0.1µF ceramic + 4.7µF tantalum) near pin 20 for AC stability. |
Key Features
| Feature | Design Value |
|---|---|
| Octal 3-State Buffer Architecture | Dual 4-bit groups with separate OE control allow selective bus segment isolation without full system reset. |
| High-Current Drive Capability | 64mA sink ensures reliable low-level signaling into 50Ω transmission lines or multi-load buses without signal degradation. |
| Power-Up 3-State Behavior | Outputs remain in high-impedance until VCC stabilizes above threshold - prevents bus contention during power ramp. |
| Latch-Up Immunity | Exceeds 500mA per JEDEC Std 17 - eliminates need for external current-limiting resistors in noisy industrial environments. |
| ESD Robustness | 2000V HBM / 200V MM - withstands handling and board assembly without special ESD precautions. |
Applications
| Industrial Backplane Interface | Memory Address Bus Driver |
|---|---|
Use Scenario: Driving parallel address/data lines between microcontroller and multiple peripheral ICs on a 12-layer industrial backplane with 8-inch trace lengths. IC Role / Device Role / Timing Role: Bidirectional bus buffer isolating CPU from peripherals; provides level-shifting margin and fanout expansion. Use Value: 2.6ns propagation delay and 64mA drive maintain signal integrity across 100+ pF net capacitance while meeting 20 ns setup/hold windows. |
Use Scenario: Expanding address bus fanout from an FPGA to eight SRAM chips in a real-time motion controller. IC Role / Device Role / Timing Role: Unidirectional address line repeater with independent group enables for bank-selectable memory access.

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 variant; identical AC/DC specs but different thermal resistance (θJA = 78°C/W vs. Nexperia's 85°C/W) and tighter IOH min (–34mA vs. –32mA). | Valid for drop-in replacement in existing SO20 layouts; preferred where higher thermal margin is required at 100mA total load. | Select SN74ABT241DBR if board-level thermal simulation shows junction temp >125°C under worst-case load. |
| 74LVT241PW,118 | Nexperia TSSOP-20 version; same logic function but lower drive (32mA sink), lower ICCZ (30µA), and 3.3V-only VCC range (2.7–3.6V). | Requires voltage translation for 5V systems; suited for mixed-voltage boards with 3.3V core logic and 5V peripherals. | Choose 74LVT241PW,118 only when migrating to 3.3V domain and reducing power is prioritized over drive strength. |
Compared with SN74ABT241DBR and 74LVT241PW,118, the 74ABT241D,623 delivers optimal balance of 5V compatibility, 64mA drive, and SO20 manufacturability - making it the default choice for new 5V industrial bus designs where thermal headroom and legacy interface compliance are critical.

FAQ
What is the maximum operating temperature range for the 74ABT241D,623?
The 74ABT241D,623 is rated for continuous operation from –40°C to +85°C ambient temperature, fully qualified per industrial standards. This range is confirmed in the "Recommended Operating Conditions" section of the Nexperia datasheet, and applies to all package variants including the SO20 (SOT163-1) form factor of the 74ABT241D,623. Junction temperature must not exceed 150°C under any condition.
Does the 74ABT241D,623 support hot insertion or live bus swapping?
The 74ABT241D,623 incorporates power-up 3-state functionality and exceeds 200V Machine Model ESD protection, which mitigates damage during hot insertion. However, it lacks explicit hot-swap circuitry (e.g., slew-rate control or undervoltage lockout), so controlled power sequencing and series resistors are recommended. The 74ABT241D,623 datasheet confirms safe operation only after VCC stabilization.
Can the 74ABT241D,623 drive a 50Ω transmission line directly?
Yes - the 74ABT241D,623 can directly drive a 50Ω line: its 64mA sink capability delivers ~3.2V into 50Ω at VCC=5V (per VOL spec of 0.55V max @ 64mA), satisfying TTL logic thresholds. Rise/fall times remain sub-3ns due to low COUT (7pF), making the 74ABT241D,623 suitable for point-to-point 50Ω routing without termination resistors in short-run applications.
What is the pinout compatibility between 74ABT241D,623 and 74ABT241N,623?
The 74ABT241D,623 (SO20/SOT163-1) and 74ABT241N,623 (DIP20/SOT146-1) share identical pin functions and numbering per the Philips/Nexperia pin configuration diagram. Both use the same 20-pin layout with 1OE, 1A0–1A3, 2Y0–2Y3, GND, VCC, etc., in identical positions - only package mechanicals (lead pitch, body size) differ. No PCB redesign is needed when substituting between these variants.
Is the 74ABT241D,623 RoHS compliant and lead-free?
Yes - the 74ABT241D,623 is manufactured by Nexperia in full compliance with RoHS Directive 2011/65/EU and is lead-free. The SO20 package (SOT163-1) uses matte tin (Sn) lead finish, and the device carries the "RoHS-compliant" marking per Nexperia's product change notices dated post-2006. Full compliance documentation is available via Nexperia's quality portal.
