74F1244 is an Octal buffer (3-State) produced by Philips Semiconductors. It is ideal for driving bus lines or buffer memory address registers. The outputs are capable of sinking 64mA and sourcing up to 15mA, producing very good capacitive drive characteristics. The device features two Output Enables, OEa and OEb, each controlling four of the 3-State outputs. The 74F1244 is pin and functionally compatible with the 74F244. The lower power and light bus loading features make it an ideal part to interface directly with MOS microprocessors.
The Philips 74F1244 is an octal buffer designed for driving bus lines or buffering memory address registers.
