Introduction
SN74ACT32DR High-Speed CMOS 4-Channel 2-Input Positive OR Gate – 4.5V-5.5V Voltage, ±24mA Drive, -40℃~85℃ Temp Range, Ideal for Industrial Control, Automotive Electronics & Consumer Devices
The SN74ACT32DR is a high-speed 4-channel 2-input OR gate manufactured by Texas Instruments (TI), belonging to the ACT logic family—a series optimized for combining CMOS low-power advantages with TTL-compatible input/output (I/O) characteristics. It is designed to deliver reliable digital logic operation in high-speed systems, making it a key component for logic combination, signal buffering, and data path expansion in diverse electronic applications.
Core Functional Characteristics
- Multi-Channel Logic Operation: Integrates 4 independent 2-input OR gates in a single package. Each gate follows standard OR logic: output is HIGH if at least one of the two inputs (A/B) is HIGH; output is LOW only when both inputs are LOW.
- High-Speed Performance: Achieves fast switching speeds with typical propagation delay (tPD) of 4.5 ns at 5 V supply voltage (load = 50 pF), enabling synchronization with high-speed data buses (e.g., 200+ MHz signal paths).
- Dual Compatibility: Features TTL-compatible inputs and CMOS-compatible outputs, supporting seamless integration with both TTL and CMOS-based systems.
- Bus Hold Function: Does not require external pull-up/down resistors for unused inputs—idle inputs can be left floating without causing unstable output.
