CD54AC280F3A

Overview

The CD54AC280F3A is a military-grade 9-bit odd/even parity generator/checker utilizing Advanced CMOS Logic technology. It operates within a supply voltage range of 1.5V to 5.5V and supports an operating temperature range from -55°C to +125°C. The device features buffered inputs, balanced propagation delays, and provides both even (E) and odd (O) parity outputs for words up to nine bits long. It offers a typical propagation delay of 10ns at VCC = 5V and includes SCR-latchup-resistant circuit design.

Feature Summary

• Provides simultaneous even and odd parity generation or checking for data words up to nine bits in length
• Features buffered inputs and balanced propagation delays with significantly reduced power consumption compared to bipolar equivalents
• Incorporates SCR-latchup-resistant CMOS process and circuit design for enhanced reliability

Applications

• Military and defense electronic systems requiring parity verification
