Product details
Overview
CD74ACT241M96 from Texas Instruments is an octal non-inverting 3-state buffer/line driver with dual independent output enables (one active-low, one active-high), designed for bidirectional bus interface and data routing in industrial and embedded systems. It operates at 4.5–5.5 V, delivers ±24 mA output drive, supports 50-Ω transmission-line driving, and features balanced propagation delays (tPLH/tPHL ≤ 8.7 ns at 5 V) and low quiescent current (≤80 μA).
For engineers reviewing the CD74ACT241M96 datasheet, CD74ACT241M96 pinout, CD74ACT241M96 application, or CD74ACT241M96 equivalent, key selection criteria include its ACT-series TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V), 20-pin SOIC (DW) package, dual OE control logic, and guaranteed operation from –40°C to +85°C.
Technical Context
The CD74ACT241M96 implements two independent 4-bit banks (Bank 1: A0–A3 → Y0–Y3; Bank 2: A0–A3 → Y0–Y3), each with separate output enable (1OE active-low, 2OE active-high). Its RCA Advanced CMOS process ensures SCR latch-up resistance and compatibility with TTL-level inputs while maintaining CMOS power efficiency.
It supports simultaneous switching of multiple outputs without violating VOHV (min. 4 V) or VOLP (max. 1 V) limits under 50-pF load conditions, and its 10 pF input capacitance and 15 pF 3-state output capacitance minimize signal integrity degradation in high-speed digital buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures robust operation across standard 5 V rail tolerances and noise margins. |
| Output Drive | ±24 mA - Sufficient to directly drive 50 Ω transmission lines or fan out to 15 FAST ICs. |
| Propagation Delay | ≤8.7 ns (tPLH/tPHL, VCC = 5 V) - Enables reliable timing in 100+ MHz bus applications. |
| Input Thresholds | VIH = 2 V, VIL = 0.8 V - TTL-compatible logic levels ensure interoperability with legacy 5 V logic families. |
| Quiescent Current | ≤80 μA (TA = –40°C to +85°C) - Supports low-power standby modes in battery-backed or energy-sensitive systems. |
| 3-State Leakage | ±5 μA max - Minimizes bus contention current when outputs are disabled. |
| Operating Temp | –40°C to +85°C - Qualified for industrial-grade environmental reliability. |
Pinout & Package
CD74ACT241M96 is housed in a 20-pin SOIC (DW) package measuring 12.8 mm × 10.3 mm (including pins), with body size 12.8 mm × 7.5 mm. The device uses standard JEDEC MS-013 outline and is RoHS-compliant with NiPdAu lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE | Active-low bank 1 output enable | Drives all Y0–Y3 outputs low-impedance when logic low; high-impedance when high. |
| 2OE | Active-high bank 2 output enable | Drives all Y0–Y3 outputs low-impedance when logic high; high-impedance when low. |
| 1A0–1A3, 2A0–2A3 | Input channels (two banks) | Accept TTL-compatible signals; each bank isolated for independent control. |
| 1Y0–1Y3, 2Y0–2Y3 | Non-inverting buffered outputs | Deliver rail-to-rail CMOS outputs with ±24 mA drive strength per pin. |
| VCC, GND | Power and ground | Single 5 V supply; requires local 0.1 μF bypass capacitor per VCC pin. |
Key Features
| Feature | Design Value |
|---|---|
| SCR-latch-up-resistant process | Guarantees immunity to destructive latch-up under transient overvoltage or ESD stress. |
| Balanced tPLH/tPHL delays | Minimizes skew between rising/falling edges-critical for clean clock/data alignment in synchronous buses. |
| 50-Ω transmission-line drive | Enables direct connection to controlled-impedance PCB traces without external termination resistors. |
| TTL-compatible input thresholds | Eliminates need for level-shifting when interfacing with legacy 5 V microcontrollers or FPGAs. |
| Low dynamic power (CPD = 71 pF) | Reduces switching power dissipation in high-frequency data paths compared to bipolar alternatives. |
Applications
| Industrial PLC Backplane Interface | Automotive Body Control Module Bus Isolation |
|---|---|
Use Scenario: Bidirectional data routing between CPU and I/O expansion cards in modular PLC chassis using parallel address/data buses. IC Role / Device Role / Timing Role: Octal buffer isolates and strengthens signals across backplane connectors; dual OE allows time-multiplexed access to shared bus segments.

| Test Equipment Digital Pattern Generator | Medical Imaging Data Acquisition Interface |
Use Scenario: Driving high-speed digital stimulus patterns onto DUT input pins in automated test systems with variable load capacitance. IC Role / Device Role / Timing Role: Provides precise, low-skew waveform replication with programmable output enable for pattern gating. Use Value: Balanced propagation delays (<0.5 ns skew) preserve pattern edge alignment; 50 Ω drive capability eliminates external termination on fixture PCBs. | Use Scenario: Interfacing FPGA-based image processing cores with analog front-end ADCs/DACs in portable ultrasound devices. IC Role / Device Role / Timing Role: Buffers parallel pixel data streams between processing engine and sensor interface, enabling voltage-level translation and bus loading isolation. Use Value: Low 80 μA ICC supports battery-operated mode; 10 pF input capacitance prevents timing degradation in 20+ MHz pixel clocks. |
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 |
|---|---|---|---|
| SN74ACT241DWR | Identical electrical specs and pinout; same SOIC-20 (DW) package; TI second-source part with identical marking (ACT241M). | No functional difference; qualified for same industrial temperature range (–40°C to +85°C). | Select when requiring alternate TI manufacturing lot traceability or dual-sourcing assurance. |
| 74ACT241SCX | Same logic function and AC/ACT specs but offered in SOIC-20 by ON Semiconductor; minor differences in ICC max (160 μA vs. 80 μA typical) and thermal resistance (RθJA = 105°C/W vs. 101.2°C/W). | Valid for commercial/industrial use but not qualified for extended temp (–55°C to +125°C) operation like CD74ACT241M96. | Choose for cost-sensitive designs where full industrial temp range is not required and sourcing flexibility is prioritized. |
Compared with SN74ACT241DWR and 74ACT241SCX, CD74ACT241M96 offers tighter quiescent current control (≤80 μA) and full industrial temperature qualification, making it preferred for mission-critical embedded systems demanding long-term reliability and thermal margin.

FAQ
What is the maximum operating temperature range for CD74ACT241M96?
The CD74ACT241M96 is rated for operation from –40°C to +85°C, meeting industrial temperature requirements. This range is verified per TI's recommended operating conditions and applies specifically to the CD74ACT241M96 variant in SOIC-20 (DW) packaging, as confirmed in Section 4.2 of the SCHS287C datasheet.
Does CD74ACT241M96 support 3.3 V logic interfaces?
No, CD74ACT241M96 does not support 3.3 V operation. Its recommended supply voltage is strictly 4.5 V to 5.5 V, and its input thresholds (VIH = 2 V, VIL = 0.8 V) are optimized for 5 V TTL compatibility-not 3.3 V LVTTL or LVCMOS. Using it with 3.3 V inputs risks unreliable logic recognition.
How many output enable controls does CD74ACT241M96 have, and what are their polarities?
CD74ACT241M96 has two independent output enables: 1OE (pin 1) is active-low, controlling Bank 1 outputs (1Y0–1Y3); 2OE (pin 19) is active-high, controlling Bank 2 outputs (2Y0–2Y3). This asymmetric polarity enables flexible bus arbitration schemes, such as one-way enable gating or staggered activation.
Can CD74ACT241M96 drive 50 Ω transmission lines directly?
Yes, CD74ACT241M96 is explicitly characterized to drive 50 Ω transmission lines, verified per Section 4.5 of the datasheet. At VCC = 4.5 V and TA = +85°C, it delivers ≥3.8 V VOH and ≤0.44 V VOL into 50 Ω loads-meeting industry-standard line-driving requirements without external series termination.
Is CD74ACT241M96 pin-compatible with CD74AC241M96?
Yes, CD74ACT241M96 is pin-compatible with CD74AC241M96, sharing identical SOIC-20 (DW) footprint and pin functions. However, they differ electrically: CD74AC241M96 operates from 1.5 V to 5.5 V and has lower drive (±24 mA only at 5 V), while CD74ACT241M96 is optimized for 4.5–5.5 V with guaranteed TTL-compatible thresholds and faster switching.
