74HC280 9-Bit Parity Generator/Checker
A versatile IC for generating or checking even/odd parity in data bits.
- Supply Voltage (VCC): -0.5 to +7V
- Input Clamping Current: 0 to +20mA
- Ambient Temperature: -40 to +125°C
- Input Rise or Fall Times: 0-625 ns/V
- Total Power Dissipation: 500mW
- Output Current: +25mA
- Supply Current: 50mA
Top Features:
- Word-length easily expanded by cascading
- Similar pin configuration to the “180” for easy system up-grading
- Generates either odd or even parity for nine data bits
- Output capability: standardICC category: MSI
Both even and odd parity outputs are available with the 74HC280 IC. The even parity output (PE) goes HIGH when an even number of data inputs (I0 to I8) are HIGH, while the odd parity output (PO) goes HIGH when an odd number of data inputs are HIGH. Expansion to larger word sizes is achieved by connecting the even outputs (PE) of up to nine parallel devices to the final stage data inputs. Inputs include clamp diodes, allowing the use of current limiting resistors to interface inputs to voltages exceeding VCC.
Package Includes: 1 X 74HC280 IC - (SMD Package) 9-bit Parity Generator IC (74280 IC)
