Overview
The SN74ABT125DB, produced by Texas Instruments, is a quadruple bus buffer gate with TTL-compatible CMOS inputs and 3-state outputs. This device is designed to provide independent line drivers, each with its own output-enable (OE) input. The SN74ABT125DB is available in a 14-pin SSOP (DB) package and is fully specified for hot-insertion applications, making it suitable for a variety of digital logic and bus buffering needs.
