In high-performance systems, thesedevices can be used to minimize the effects ofsystem decoding. When employed withhigh-speed memories with a fast enable circuit,the delay times of the decoder and the enable timeof the memory are usually less than the typicalaccess time of the memory. The effective systemdelay introduced by the Schottky-clamped systemThe conditions at the binary-select (A, B, and C) , and G2B inputs select one of eight output lines. Twoactive-low and one active-high enable inputsreduce the need for external gates or inverters when expanding. A 24-line decoder can be implemented withoutexternal inverters and a 32-line decoder requires only one inverter. An enable input can be used as a data inputfor demultiplexing applications.

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 substancedo 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 mayreference 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 threshold. Antimony trioxide basedflame retardants must also meet the threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuationof the previous line and the two combined represent the entire Device Marking for that device.
