Product details

Overview

SN74AC241PWR from Texas Instruments is an octal 3-state buffer/driver IC designed for memory address, clock, and bus interface applications. It operates across 2V–6V V_CC, supports input voltages up to 6V, delivers ≤7.5ns propagation delay at 5V, and features dual independent output-enable controls (1OE/2OE) for flexible bus management in industrial and embedded systems.

For engineers reviewing the SN74AC241PWR datasheet, SN74AC241PWR pinout, SN74AC241PWR application, or SN74AC241PWR equivalent, key selection criteria include its 20-pin TSSOP package, rail-to-rail input tolerance, high-speed 3-state drive capability, and compatibility with mixed-voltage logic interfaces in memory subsystems and data buses.

Technical Context

The SN74AC241PWR implements two independent 4-bit noninverting buffer sections, each with dedicated complementary output-enable inputs (1OE active-low, 2OE active-high). Its CMOS AC logic family ensures fast switching with low power consumption and high noise immunity.

Each buffer section drives one of eight Y outputs from corresponding A inputs only when its enable condition is met; otherwise, outputs enter high-impedance state. This architecture enables bidirectional bus control without external direction logic, supporting time-multiplexed address/data paths and clock distribution networks.

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
SN74LVC241APWR	Lower V_CC range (1.65–3.6V); 3.3V-only optimized; 5.5ns t_pd at 3.3V	Better suited for modern low-voltage SoC interfaces; not 5V-tolerant	Select when operating exclusively at 3.3V and requiring faster switching than SN74AC241PWR
SN74HCT241PW	TTL-compatible input thresholds; 4.5–5.5V V_CC only; 21ns t_pd at 5V	Designed for legacy 5V TTL systems; higher power consumption	Choose for backward compatibility with older 5V logic families where AC speed is secondary to voltage-level matching

Compared with SN74LVC241APWR and SN74HCT241PW, the SN74AC241PWR uniquely bridges 3.3V and 5V domains with rail-to-rail input tolerance and sub-8ns speed-making it optimal for mixed-voltage industrial controllers where interoperability and timing margin are both critical.

FAQ

What is the maximum operating voltage for SN74AC241PWR?

The SN74AC241PWR supports a supply voltage range of 2V to 6V. Its inputs tolerate voltages up to V_CC + 0.5V, enabling safe interfacing with 5V signals even when powered from 3.3V. Absolute maximum ratings specify V_CC up to 7V, but sustained operation above 6V is not recommended per TI's recommended operating conditions. The SN74AC241PWR must never be operated outside its specified 2–6V window for reliable functionality.

Does SN74AC241PWR support 3.3V and 5V logic level translation?

Yes, the SN74AC241PWR provides inherent level translation capability due to its rail-to-rail input voltage tolerance (–0.5V to V_CC + 0.5V) and wide V_CC range (2V–6V). When powered at 3.3V, it accepts 5V inputs without damage or external clamping. Outputs swing fully to V_CC, so 3.3V-powered SN74AC241PWR drives 3.3V logic levels, while 5V-powered units drive 5V levels. This makes the SN74AC241PWR suitable for bidirectional voltage translation in mixed-signal systems.

What is the function of Pin 1 (1OE) and Pin 19 (2OE) on SN74AC241PWR?

Pin 1 (1OE) is the active-low output enable for the first four buffers (1A1–1A4 → 2Y1–2Y4), while Pin 19 (2OE) is the active-high output enable for the second four buffers (2A1–2A4 → 1Y1–1Y4). When 1OE is low, the first section passes data; when high, its outputs go high-impedance. When 2OE is high, the second section passes data; when low, its outputs go high-impedance. This dual-control architecture allows independent management of two 4-bit data paths, a key feature of the SN74AC241PWR.

Can SN74AC241PWR drive standard TTL loads?

Yes, the SN74AC241PWR can directly drive standard TTL loads. At V_CC = 5V, it delivers I_OL = 24mA and I_OH = –24mA, exceeding the ±16mA requirement of standard TTL. Its output voltage specifications (V_OL ≤ 0.44V and V_OH ≥ 3.76V at 24mA) also meet TTL logic thresholds. This capability is confirmed in the SN74AC241PWR's electrical characteristics table and makes it suitable for interfacing with legacy TTL-based peripherals without additional drivers.

Is SN74AC241PWR pin-compatible with other TSSOP-20 octal buffers?

The SN74AC241PWR shares the same TSSOP-20 (PW) mechanical footprint and pinout as TI's SN74LVC241APWR and SN74HCT241PW, including identical pin numbering and functional assignment (e.g., 1OE on Pin 1, V_CC on Pin 20). However, electrical behavior differs significantly-especially input threshold compatibility and voltage range-so direct substitution requires validation of system-level timing, voltage margins, and enable logic polarity. The SN74AC241PWR is not a drop-in replacement without design review.
