NXP Semiconductors N74F241N,602

Overview

N74F241N,602 from Philips Semiconductors is an octal 3-state buffer IC designed for bidirectional bus interface and memory address register driving in TTL-compatible digital systems. It features dual independent output enables (OEa/OEb), sinks up to 64 mA per output in LOW state, sources up to 15 mA in HIGH state, and delivers 4.0 ns typical propagation delay at 5 V supply. It operates across 0 °C to +70 °C with 20-pin plastic DIP (SOT146-1) packaging.

For engineers reviewing the N74F241N,602 datasheet, N74F241N,602 pinout, N74F241N,602 application, or N74F241N,602 equivalent, key selection criteria include dual 4-bit 3-state control, IOL = 64 mA/IOH = –15 mA drive strength, 5 V ±10 % supply tolerance, 50 pF load AC timing, and compatibility with legacy 74F logic families in industrial control and data acquisition systems.

Technical Context

The N74F241N,602 implements two independent 4-bit non-inverting 3-state buffers, each controlled by a dedicated enable input (OEa for Ya0–Ya3, OEb for Yb0–Yb3). Its TTL-compatible inputs accept VIH ≥ 2.0 V and VIL ≤ 0.8 V, while outputs meet VOH ≥ 2.4 V (IOH = –3 mA) and VOL ≤ 0.50 V (IOL = 64 mA).

AC performance is characterized at CL = 50 pF and RL = 500 Ω: tPLH/tPHL = 4.0 ns typical, tPZH/tPZL = 4.0 ns typical (enable-to-output), and tPHZ/tPLZ = 4.0 ns typical (disable-from-output). The device uses standard bipolar F (Fast TTL) process technology and requires no external biasing or termination for nominal operation.

FAQ

What is the maximum output sink current specification for N74F241N,602?

The N74F241N,602 specifies a maximum low-level output current (IOL) of 64 mA per output pin under recommended operating conditions (VCC = 4.5 V to 5.5 V, Tamb = 0 °C to +70 °C). This rating is verified per the manufacturer's DC electrical characteristics table and applies individually to each of the eight 3-state outputs (Ya0–Ya3, Yb0–Yb3) when actively driven LOW.

Does N74F241N,602 support dual independent output enables, and how are they assigned?

Yes, N74F241N,602 features two active-low output enables: OEa (Pin 1) controls outputs Ya0–Ya3, and OEb (Pin 19) controls outputs Yb0–Yb3. Each group operates independently-enabling one group while disabling the other places only its four outputs in high-impedance state, allowing concurrent use of both 4-bit paths on shared bus infrastructure.

What is the typical propagation delay of N74F241N,602, and under what test conditions is it measured?

The typical propagation delay (tPLH/tPHL) of N74F241N,602 is 4.0 ns, measured at VCC = 5.0 V, Tamb = +25 °C, with CL = 50 pF and RL = 500 Ω load. This value applies to transitions from any input (Ia0–Ia3, Ib0–Ib3) to its corresponding output (Ya0–Ya3, Yb0–Yb3) and is consistent across all eight channels.

Is N74F241N,602 pin-compatible with other 74F-series octal buffers like 74F240 or 74F244?

No, N74F241N,602 is not pin-compatible with 74F240 (inverting) or 74F244 (non-inverting but single-enable). Its unique pinout includes dual enables (Pins 1 and 19) and interleaved I/O arrangement (e.g., Pin 2 = Ia0, Pin 3 = Yb0). Substitution requires PCB layout revision unless using functionally matched replacements like SN74F241N.

What package type does N74F241N,602 use, and what is its JEDEC designation?

N74F241N,602 uses a 20-pin plastic dual in-line package (DIP) with 300 mil body width, designated SOT146-1 by Philips and commonly referenced as JEDEC MS-001. It is through-hole mountable, RoHS-compliant per original manufacturing spec, and compatible with standard DIP sockets and wave-solder processes.
