CD54/74AC280, CD54/74ACT280 Data sheet acquired from Harris Semiconductor SCHS250A 9-Bit Odd/Even Parity Generator/Checker August 1998 - Revised May 2000 Features data inputs is HIGH. Odd parity is indicated (∑O output is HIGH) when an odd number of data inputs is HIGH. Parity checking for words larger than nine bits can be accomplished by tying the ∑E output to any input of an additional ’AC280, ’ACT280 parity checker. • Buffered Inputs • Typical Propagation Delay - 10ns at VCC = 5V, TA = 25oC, CL = 50pF • Exceeds 2kV ESD Protection per MIL-STD-883, Method 3015 Ordering Information PART NUMBER • SCR-Latchup-Resistant CMOS Process and Circuit Design TEMP.

When ordering, use the entire part number. Add the suffix 96 to obtain the variant in the tape and reel. The ’AC280 and ’ACT280 are 9-bit odd/even parity generator/checkers that utilize Advanced CMOS Logic technology. Both even and odd parity outputs are available for checking or generating parity for words up to nine bits long. Even parity is indicated (∑E output is HIGH) when an even number of 2. Wafer and die for this part number is available which meets all electrical specifications. Please contact your local TI sales office or customer service for ordering information.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
