What are the key features of CD74ACT280E?
- 9-bit odd/even parity generation and checking in a single IC, reducing logic count in error-detection data paths
- ACT family high-speed CMOS with 5 ns propagation delay and 75 mA output sink current for bus-driving capability
- Standard 14-pin DIP package for easy through-hole prototyping and legacy system maintenance
What is CD74ACT280E used for?
CD74ACT280E is used in digital communication and memory systems requiring hardware parity error detection across 8-bit or 9-bit data words, such as DRAM parity interfaces, UART data path checking, and parallel bus integrity verification. Its ACT family speed and 75 mA sink current allow it to drive bus lines directly without buffering in systems up to 5 V logic levels. Legacy industrial and embedded controllers using through-hole PCB construction rely on CD74ACT280E for reliable single-bit error detection in data transmission paths.

Frequently Asked Questions
How fast is CD74ACT280E's propagation delay and at what supply and load conditions is it specified?
CD74ACT280E achieves a typical propagation delay of approximately 5 ns at a 5 V supply with a 50 pF load capacitance, making it one of the fastest standard logic parity devices available in a 14-pin DIP package. This speed supports data bus error checking in systems clocked above 50 MHz.
Can CD74ACT280E detect single-bit errors on a byte-wide data bus, and how wide is its parity function?
CD74ACT280E generates and checks parity across a 9-bit word, covering 8 data bits plus 1 parity bit. When the 9-bit input XORs to an odd or even result, the corresponding parity output signals a parity match or error. This makes it directly usable as a single-bit error detector on 8-bit parallel data buses such as ISA, parallel DRAM, or legacy industrial field buses.
What is the output sink current of CD74ACT280E, and can it drive TTL bus loads without buffering?
CD74ACT280E can sink up to 75 mA at its output pins, far exceeding the typical 4 mA to 8 mA of standard CMOS logic. This high sink current allows it to directly drive heavily loaded TTL-level bus lines with multiple receivers without the need for additional bus buffer ICs, simplifying the PCB design in backplane or multi-card data systems.
Is CD74ACT280E compatible with 3.3 V CMOS inputs when powered from a 5 V supply?
CD74ACT280E belongs to the ACT family, which uses TTL-compatible input thresholds (V_IH min 2.0 V, V_IL max 0.8 V). A 3.3 V CMOS output driving above 2.4 V for logic-high is reliably recognized by CD74ACT280E operating at 5 V, enabling mixed 3.3 V and 5 V system integration without level-shift buffers in most cases.
