What are the key features of CD74ACT02M?
- ACT family quad 2-input NOR gate with 24 mA sink current, enabling direct drive of multiple bus lines or LED indicators without external buffers
- TTL-compatible input thresholds at 4.5 V to 5.5 V supply allow direct connection from 5 V TTL logic to CMOS outputs in mixed-technology board designs
- 4 independent NOR gates in 14-pin SOIC package provide dense logic integration for combinational circuits, priority encoders, and clock gating
What is CD74ACT02M used for?
The CD74ACT02M provides four independent NOR logic functions used in combinational boolean logic, address decoding, and clock or reset gating circuits in 5 V digital systems. Its ACT family TTL-compatible inputs allow direct interfacing between legacy 5 V TTL bus systems and newer CMOS peripheral devices. The 14-pin SOIC package suits surface-mount PCB designs in industrial controllers, communication equipment, and computing peripherals requiring standard glue logic functions.

Frequently Asked Questions
How does the ACT logic family of CD74ACT02M differ from standard HC in terms of input compatibility?
The ACT (Advanced CMOS with TTL inputs) family uses TTL-compatible input thresholds: logic high above 2.0 V and logic low below 0.8 V, at a 5 V supply. Standard HC gates require CMOS input levels of VCC x 0.7 = 3.5 V for logic high at 5 V, meaning direct connection from 5 V TTL drivers to HC inputs can cause undefined states. The CD74ACT02M eliminates this issue by accepting TTL-level swings directly.
What is the maximum output sink current of the CD74ACT02M, and how many TTL inputs can one gate drive?
Each gate output of the CD74ACT02M can sink 24 mA, compared to 4 mA for standard HC gates. This 24 mA drive current supports up to 24 standard TTL inputs with 1 mA input load each, or can directly drive low-current LEDs, logic level indicators, or high-capacitance bus lines without intermediate buffer stages.
For a 5 V digital system design, can the CD74ACT02M replace a 74LS02 NOR gate directly?
Yes, the CD74ACT02M is pin-compatible with the 74LS02 in the 14-pin SOIC package and accepts the same TTL-level input voltages. It provides 24 mA sink current compared to 8 mA for 74LS02, and propagation delays below 10 ns at 5 V—faster than 74LS02's typical 10 ns to 15 ns. This makes it a direct performance upgrade in existing 5 V TTL designs without schematic changes.
In a PCB redesign moving from DIP to surface-mount logic, how compact is the CD74ACT02M SOIC-14 footprint?
The SOIC-14 package of CD74ACT02M has a 8.7 mm body length, 3.9 mm width, and 1.27 mm pin pitch, occupying roughly 34 mm² of PCB area. This is approximately 60% smaller than a standard DIP-14 package footprint of 19 mm x 7.62 mm, freeing significant board space when converting legacy through-hole logic designs to surface-mount assembly.
