CD74AC02 is a quad 2-input NOR gate manufactured by Texas Instruments (TI). It utilizes Advanced CMOS Logic technology. The circuit has a typical propagation delay of 6ns (VCC = 5V, TA = 25oC, CL = 50pF), exceeds 2kV ESD protection (MIL-STD-883, Method 3015), SCR-Latchup-Resistant CMOS process and circuit design, speed of Bipolar FAST™/AS/S with significantly reduced power consumption, balanced propagation delays, AC types feature 1.5V to 5.5V operation and balanced noise immunity at 30% of the supply voltage, ±24mA output drive current - fanout to 15 FAST™ ICs - drives 50Ω transmission lines.
The CD54/74AC02 and CD54/74ACT02 are quad 2‑input NOR gates built with advanced CMOS logic technology. They feature a typical propagation delay of 6 ns at 5 V supply, 24 mA output drive current, and balanced propagation delays across all inputs. The devices operate from 1.5 V to 5.5 V (AC types) or 4.5 V to 5.5 V (ACT types) and provide up to 50 mA of source or sink current per output pin.
Ordering information includes three package options: 14‑lead CERDIP, PDIP, and SOIC, all rated for -55 °C to 125 °C. The datasheet lists absolute maximum ratings, thermal specifications, detailed DC electrical parameters, and switching characteristics such as input capacitance (10 pF) and propagation delay under various temperature and voltage conditions. Proper ESD handling is required.
