CD54ACT280F3A

Overview

The CD54ACT280F3A is a military-grade, 9-bit odd/even parity generator/checker utilizing Advanced CMOS Logic technology. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -55°C to +125°C. The device features buffered inputs 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, TA = 25°C, with CL = 50pF. The component exceeds 2kV ESD protection per MIL-STD-883, Method 3015, and utilizes an SCR-latchup-resistant process.

Feature Summary

• Provides simultaneous generation and checking of odd and even parity for data words up to nine bits in length.
• Features buffered inputs and balanced propagation delays for reliable signal integrity.
• Exceeds 2kV electrostatic discharge (ESD) protection requirements as defined by MIL-STD-883, Method 3015.
• Utilizes an SCR-latchup-resistant CMOS process that delivers speed comparable to Bipolar FAST/AS logic with significantly reduced power consumption.

Applications

• Military and defense electronic systems requiring high reliability and radiation-hardened specifications.
• Data transmission interfaces requiring parity verification for error detection.
• High-speed digital logic circuits needing latch-up resistance and extended temperature tolerance.
• Complex computing architectures utilizing Advanced CMOS logic families.

Procurement Notes

Verify the complete part number including suffixes when ordering, as variations exist for different packaging or material compositions. Confirm that the specific variant meets all electrical specifications required for your application. Contact Texas Instruments directly for wafer or die availability inquiries. Ensure compliance with relevant military standards if the device is intended for defense applications. Review the latest package option addendum for current status and material details.

Selection Notes

Select this component when a 9-bit parity solution is required within the ACT logic family. Ensure the design environment accommodates the 4.5V to 5.5V supply voltage constraint. Verify that the ceramic dual in-line package (CDIP) fits the mechanical constraints of the target assembly. Consider the extended temperature range capabilities for harsh environments. Evaluate the need for ESD protection exceeding standard commercial levels.

Part Context

This device belongs to the CD54/74AC280 and CD54/74ACT280 series of parity generators/checkers. The 'CD54' prefix indicates a military-grade qualification, while 'ACT' specifies the Advanced CMOS technology with a 5V nominal supply. It is functionally compatible with other devices in the AC/ACT logic family, allowing integration into broader digital systems designed around these standards.
