The SN74ALS29827 provides true data and the SN74ALS29828 provides inverted data at their respective outputs. The SN74ALS29827 and SN74ALS29828 are characterized for operation from 0°C to 70°C. logic symbols† SN74ALS29827 1 OE1 OE2 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 13 SN74ALS29828 & 1 OE1 EN OE2 2 23 3 22 4 21 5 20 6 19 7 18 8 17 9 16 10 15 11 14 Y1 A1 Y2 A2 Y3 A3 Y4 A4 Y5 A5 Y6 A6 Y7 A7 Y8 A8 Y9 A9 Y10 A10 13 & EN 2 23 3 22 4 21 5 20 6 19 7 18 8 17 9 16 10 15 11 14 Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 Y9 Y10 † These symbols are in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.

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
