NXP Semiconductors 74ABT241D,602

Overview

74ABT241D,602 from Nexperia is an octal 3-state buffer/line driver in 20-pin SO package, designed for bidirectional bus interface applications with ±64mA/–32mA output drive, 2.6ns typical propagation delay (tPLH), and dual independent output enables (1OE, 2OE). It operates across –40°C to +85°C at 4.5V–5.5V supply.

For engineers reviewing the 74ABT241D,602 datasheet, 74ABT241D,602 pinout, 74ABT241D,602 application, or 74ABT241D,602 equivalent, key selection criteria include high-current drive capability, low propagation delay, power-up 3-State behavior, input disable during 3-State mode, and compatibility with 5V TTL logic systems.

Technical Context

The 74ABT241D,602 implements a high-performance BiCMOS architecture delivering low static/dynamic power with high-speed switching. Its dual 4-bit groups (1A0–1A3/1Y0–1Y3 and 2A0–2A3/2Y0–2Y3) are independently controlled by 1OE and 2OE, enabling selective bus segmentation without contention.

Each output supports rail-to-rail switching with guaranteed VOH ≥2.0V at –32mA and VOL ≤0.55V at 64mA under VCC = 4.5V. Input clamp voltage (VIK) is –1.2V, and ESD protection exceeds 2000V (MIL-STD-883 Method 3015) and 200V (Machine Model).

FAQ

What is the maximum operating temperature range for the 74ABT241D,602?

The 74ABT241D,602 is rated for continuous operation from –40°C to +85°C. This range is validated per the recommended operating conditions table in the official Nexperia datasheet and applies to all package variants including the SO (SOT163-1) version. Thermal derating is not required within this span, and junction temperature remains below 150°C under specified load conditions.

Does the 74ABT241D,602 support true bidirectional data flow?

No - the 74ABT241D,602 is a unidirectional octal buffer with fixed input/output direction per channel (e.g., 1A0 → 1Y0). It does not contain internal direction-control logic or bus transceivers. Bidirectional operation requires external control of OE pins and system-level protocol management, but the device itself only buffers in one direction per pin pair.

What is the purpose of the power-up 3-State feature in the 74ABT241D,602?

The power-up 3-State feature ensures all outputs of the 74ABT241D,602 remain in high-impedance until VCC reaches a valid operating level (~2.0V). This prevents bus contention or undefined states during power ramp-up, which is critical in systems with multiple powered components sharing a common data bus.

Can the 74ABT241D,602 be used with 3.3V logic inputs?

Yes - the 74ABT241D,602 accepts 3.3V logic-high inputs safely because its VIH threshold is only 2.0V (min) at VCC = 4.5V–5.5V. However, outputs swing to full 5V levels, so interfacing with 3.3V receivers requires external level translation or voltage-tolerant inputs to avoid damage or overstress.

How does the latch-up protection specification apply to the 74ABT241D,602?

The 74ABT241D,602 provides latch-up immunity exceeding 500mA per JEDEC Std 17. This means it can withstand transient current injection events (e.g., ESD-induced substrate currents or supply glitches) without entering destructive latch-up, ensuring reliability in electrically noisy industrial environments where such faults may occur.
