SDAS277 − JANUARY 1995 OE 1D 2D 3D 4D 5D 6D 7D 8D GND description These octal D-type transparent latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. 1 20 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 12 10 11 VCC 1Q 2Q 3Q 4Q 5Q 6Q 7Q 8Q LE 2D 1D SN54ALS580B . . . FK PACKAGE (TOP VIEW) While the latch-enable (LE) input is high, outputs (Q) respond to the data (D) inputs. When LE is low, the outputs are latched to retain the data that was set up. 3D 4D 5D 6D 7D 4 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 2Q 3Q 4Q 5Q 6Q 8D GND LE 8Q 7Q A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without interface or pullup components. 3 1Q • • • SN54ALS580B . . .

Old data can be retained or new data can be entered while the outputs are in the high-impedance state. The SN54ALS580B is characterized for operation over the full military temperature range of − 55°C to 125°C. The SN74ALS580B and SN74AS580 are characterized for operation from 0°C to 70°C.

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
