SN74LS244DWR from TI is an octal buffer\/line driver with 3-state outputs, organized as two 4-bit groups. 5V LS TTL. SOIC-20W.<\/p>\n

Principio de funcionamiento<\/h2>\n

Two independent 4-bit buffers with separate output-enable (1G, 2G) for bus-oriented applications. 3-state outputs. High output drive capability (24mA sink, 15mA source). Typical propagation 12ns. Ideal for driving bus lines and address buffers.<\/p>\n
