产品概览
The SN74HC541PW from Texas Instruments is an octal buffer and line driver with 3-state outputs in a 20-pin TSSOP package. With two active-low output-enable (OE) inputs controlling 4 outputs each, 6V supply range, and 12mA output drive, it provides robust bus buffering for microprocessor and memory systems.
