DESCRIPTION

· Octal D-type transparent latches with 3-state outputs.
· Designed for driving highly capacitive or low-impedance loads.
· Suitable for buffer registers, I/O ports, bidirectional bus drivers, and working registers.
· Latch-enable (LE) input controls data retention and output response.
· Output-enable (OE) input places outputs in normal logic or high-impedance state.
· High-impedance state allows driving bus lines without interface or pullup components.
· Internal operations unaffected by OE.
· SN54ALS580B operates from -55°C to 125°C; SN74ALS580B and SN74AS580 operate from 0°C to 70°C.

FEATURES

· 3-State buffer-type outputs for direct bus line driving.
· Bus-structured pinout for efficient system integration.
· Inverting-logic outputs for versatile application.
· Available in various package options: Plastic Small-Outline (DW), Ceramic Chip Carriers (FK), Standard Plastic (N), Ceramic (J) 300-mil DIPs, and Ceramic Flat (W) packages.

APPLICATIONS

· Buffer registers for data storage and transfer.
· I/O ports for interfacing with external devices.
· Bidirectional bus drivers for communication between multiple devices.
· Working registers for temporary data holding during processing.
