The CD74HC280E from Texas Instruments is a high-speed CMOS logic device that functions as a 9-bit odd/even parity generator and checker. It provides both even and odd parity outputs, making it suitable for generating or checking parity for data words up to nine bits in length. This IC is designed for applications requiring error detection in data transmission or storage.
Key electrical characteristics include a typical propagation delay of 17ns at 5V and 15pF load capacitance. The device supports a wide operating temperature range from -55°C to 125°C. For HC types, the operating voltage is between 2V and 6V, while HCT types operate from 4.5V to 5.5V. It offers significant power reduction compared to LSTTL logic and features high noise immunity.
The CD74HC280E is supplied in a 14-pin PDIP (Plastic Dual In-line Package) with a TUBE carrier type and a standard package quantity of 25. Its standard outputs have a fanout of 10 LSTTL loads, and bus driver outputs have a fanout of 15 LSTTL loads. This component is easily cascadable for longer data word parity checks.
