Product details
Overview
74ABT241N,602 from Nexperia is an octal 3-state buffer/line driver in a 20-pin plastic DIP package, designed for high-speed bus interface applications with ±64mA/–32mA output drive capability, 2.6ns typical propagation delay (An to Yn), and operation across –40°C to +85°C. It features dual independent output enables (1OE, 2OE) controlling four outputs each, enabling selective bus segmentation in industrial control backplanes.
For engineers reviewing the 74ABT241N,602 datasheet, 74ABT241N,602 pinout, 74ABT241N,602 application, or 74ABT241N,602 equivalent, key selection criteria include output drive strength under 5V supply, 3-state enable timing (tPZH ≤ 6.8ns), input/output capacitance (CIN = 3pF, COUT = 7pF), and latch-up immunity (>500mA per JEDEC 17).
Technical Context
The 74ABT241N,602 implements a BiCMOS architecture delivering low static current (ICCZ = 50µA in 3-state) while sustaining high-speed switching (tPLH/tPHL = 4.1/4.2ns max over temperature). Its dual 4-bit 3-state groups allow independent control of two bus segments without contention.
Input disable during 3-state mode prevents floating inputs from affecting downstream logic; power-up 3-state ensures outputs remain high-impedance until VCC stabilizes. Absolute maximum ratings support 7.0V VCC and –1.2V VI, enabling robust interfacing with mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5V to 5.5V - Ensures compatibility with standard 5V TTL/CMOS systems and tolerates supply ripple without functional degradation. |
| tPLH / tPHL | 4.1ns / 4.2ns max - Enables reliable data transfer at >100MHz bus clock rates with margin for trace delays. |
| IOL / IOH | 64mA / –32mA - Drives heavy capacitive loads (e.g., 10+ TTL inputs or 15cm PCB traces) without signal integrity loss. |
| CIN / COUT | 3pF / 7pF - Minimizes loading on upstream drivers and reduces crosstalk in dense bus layouts. |
| tPZH / tPHZ | 6.8ns / 7.1ns max - Guarantees deterministic bus arbitration timing when enabling/disabling multiple 74ABT241N,602 devices in parallel. |
| ESD Protection | 2000V HBM / 200V MM - Sustains handling and board-level ESD events without parameter shift or failure. |
| Latch-up Immunity | >500mA per JEDEC JESD17 - Prevents destructive latch-up during transient overvoltage or ground bounce. |
Pinout & Package
74ABT241N,602 uses a 20-pin plastic dual in-line package (DIP20, SOT146-1), 300-mil width, through-hole mountable with 2.54mm pitch. Package meets RoHS requirements and supports wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low enables for Group 1 (Y0–Y3) and Group 2 (Y4–Y7); independent control allows time-multiplexed bus access. |
| 2,4,6,8 | 1A0–1A3 | Data inputs for first 4-bit group; referenced to GND/VCC, compatible with 5V TTL logic thresholds. |
| 17,15,13,11 | 2A0–2A3 | Data inputs for second 4-bit group; electrically isolated from Group 1 inputs except via shared VCC/GND. |
| 18,16,14,12 | 1Y0–1Y3 | 3-state outputs for Group 1; sink up to 64mA or source up to 32mA while maintaining VOL ≤ 0.55V. |
| 3,5,7,9 | 2Y0–2Y3 | 3-state outputs for Group 2; identical drive capability and timing to Group 1 outputs. |
| 10 | GND | Signal reference plane; must be low-inductance connection to minimize ground bounce during simultaneous switching. |
| 20 | VCC | +5V supply rail; decoupling capacitor (100nF ceramic) required within 10mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Octal 3-State Buffer Architecture | Two independent 4-bit groups with separate enables-enables flexible bus partitioning without external logic. |
| High Sink/Source Drive | 64mA sink / 32mA source capability-drives long traces, multiple loads, or legacy TTL interfaces directly. |
| Power-Up 3-State | Outputs remain high-impedance until VCC reaches valid operating range-prevents bus contention during power sequencing. |
| Low Input Capacitance | 3pF typical-reduces loading on preceding drivers and preserves signal edge rate in high-frequency buses. |
| Latch-Up Immunity | Exceeds 500mA per JEDEC JESD17-ensures robustness against transient overcurrent events in industrial environments. |

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 |
|---|---|---|---|
| SN74ABT241N | Same pinout, identical AC/DC specs, TI-branded version with identical BiCMOS process; VCC tolerance 4.5–5.5V. | No functional difference; validated in same industrial backplane designs as 74ABT241N,602. | Select when requiring TI's documentation ecosystem or dual-sourcing from US-based distribution. |
| 74LVT241PW,118 | 3.3V-only operation (2.7–3.6V), lower drive (32mA/–24mA), 3.5ns max tPLH; TSSOP20 package (SOT360-1). | Not suitable for 5V legacy systems; requires level translation if interfacing with 5V buses. | Choose only for new 3.3V designs where space-constrained layout justifies TSSOP and reduced drive suffices. |

FAQ
What is the maximum operating temperature range for the 74ABT241N,602?
The 74ABT241N,602 is rated for continuous operation from –40°C to +85°C ambient temperature. This range is validated per the Recommended Operating Conditions table in the official Nexperia datasheet, supporting deployment in industrial enclosures and outdoor control cabinets without derating.
Does the 74ABT241N,602 support live insertion or hot-swap applications?
The 74ABT241N,602 supports hot-swap use due to its power-up 3-state feature and high latch-up immunity (>500mA). During power ramp-up, outputs remain high-impedance until VCC stabilizes above 2.0V, preventing bus contention. However, external current-limiting resistors are recommended on OE lines for full hot-swap robustness.
Can the 74ABT241N,602 drive standard TTL loads directly?
Yes-the 74ABT241N,602 can drive up to 10 standard TTL unit loads (each 1.6mA) per output while maintaining VOL ≤ 0.55V at 64mA sink, as confirmed by DC Electrical Characteristics data. Its –32mA source capability also meets TTL VOH requirements across temperature.
What is the function of the dual Output Enable (1OE and 2OE) pins on the 74ABT241N,602?
1OE controls outputs Y0–Y3 (pins 18,16,14,12); 2OE controls outputs Y4–Y7 (pins 3,5,7,9). Each enable operates independently and is active-low. This allows selective activation of either 4-bit group-essential for time-division multiplexing or partial bus isolation in complex backplane architectures.
Is the 74ABT241N,602 RoHS compliant and lead-free?
Yes-the 74ABT241N,602 is manufactured by Nexperia in a RoHS-compliant, lead-free plastic DIP package (SOT146-1). The device meets EU Directive 2011/65/EU and carries appropriate marking per Nexperia's product change notifications dated post-2006.
