Product details

Overview

SN74F241NS from National Semiconductor is an octal non-inverting buffer/line driver with dual active-Low TRI-STATE® outputs, designed for memory address driving, bus-oriented transmission, and clock distribution in TTL-compatible systems. It features 20-pin SOIC (JEDEC M20B) packaging, 64 mA sink capability per output, 12 mA source current, and guaranteed 4000V ESD protection.

For engineers reviewing the SN74F241NS datasheet, SN74F241NS pinout, SN74F241NS application, or SN74F241NS equivalent, key selection criteria include its dual independent output-enable control (OE1/OE2 active-Low), asymmetric input loading (2.667 U.L. per input), and commercial-grade operation at 4.5–5.5 V over 0°C to 70°C.

Technical Context

The SN74F241NS implements two independent 4-bit non-inverting buffer sections, each with dedicated active-Low TRI-STATE enable inputs (OE1 and OE2). Its logic function follows a true non-inverting transfer: when enabled, O_n = I_n; when disabled, outputs enter high-impedance state.

It uses standard F-series TTL circuitry with input clamp diodes for high-speed termination management and supports fan-out of up to 600 standard TTL loads on outputs. DC characteristics are specified at V_CC = 5.0 V, with VIH ≥ 2.0 V, VIL ≤ 0.8 V, VOH ≥ 2.4 V (IOH = –3 mA), and VOL ≤ 0.55 V (IOL = 64 mA).

6–9, 10–13	O0–O3, O4–O7	TRI-STATE outputs; high-impedance when corresponding OE is HIGH
10	GND	Ground reference for all logic and power domains
20	VCC	+5 V supply rail; decoupling required within 1 cm of pin

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal non-inverting TRI-STATE buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LS241N	Lower drive (24 mA sink), slower propagation (15–25 ns), LS-TTL compatible	Higher power efficiency but unsuitable for >10 MHz bus speeds or heavy capacitive loads	Select when cost-sensitive, low-speed, or legacy LS-bus compatibility is required
SN74ACT241PW	CMOS technology, 5 V tolerant, 24 mA sink, 3-state, 3.3 V compatible inputs	Supports mixed-voltage systems; lacks F-series speed and drive strength	Select for 3.3 V/5 V interfacing where F-series performance is not critical

Compared with SN74F241NS, SN74LS241N trades speed and drive for lower power and cost, while SN74ACT241PW offers voltage flexibility at reduced output strength-neither is pin-compatible, requiring layout revision for substitution.

FAQ

What is the logic configuration of the SN74F241NS?

The SN74F241NS contains two independent 4-bit non-inverting buffer sections, each with its own active-Low TRI-STATE enable input (OE1 for bits 0–3, OE2 for bits 4–7). When enabled, outputs replicate inputs; when disabled, outputs go to high-impedance state. This architecture supports flexible bus partitioning in memory and peripheral interfaces.

Does the SN74F241NS support 3.3 V operation?

No, the SN74F241NS is a 5 V-only TTL device with absolute maximum VCC of 7.0 V and recommended operating range of 4.5 V to 5.5 V. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output drive levels are optimized for 5 V TTL systems. Using it with 3.3 V supplies risks unreliable switching and violates recommended conditions.

What is the pinout compatibility between SN74F241NS and SN74F240NS?

SN74F241NS and SN74F240NS share identical pinouts and package footprints (20-pin SOIC M20B), but differ in logic behavior: SN74F240NS provides inverting outputs, while SN74F241NS provides non-inverting outputs. Both use dual active-Low OE inputs and same DC/AC specifications, enabling direct functional substitution only where inversion is acceptable or compensated externally.

Can SN74F241NS replace SN74F244NS in a design?

No-SN74F241NS and SN74F244NS have different enable logic: SN74F241NS uses two active-Low OE inputs, whereas SN74F244NS uses one active-Low and one active-High OE pair. Their truth tables and control timing differ fundamentally. Substitution would require redesign of enable signal generation and verification of timing margins, making them functionally incompatible despite identical pin counts and packages.

Is SN74F241NS still in production?

The SN74F241NS is obsolete per National Semiconductor's May 1995 datasheet and TI's post-acquisition product discontinuation notices. However, Aetrix Electronics maintains verified legacy stock with full traceability and supports extended-life procurement for industrial and defense customers requiring this exact specification and timing behavior.
