Octal 3-STATE Inverting Buffer/Line Drivers/Line Receiver
DM74AS240 • DM74AS244 3-STATE Bus Driver/Receiver October 1986 Revised March 2000 DM74AS240 • DM74AS244 3-STATE Bus Driver/Receiver General Description Features This family of Advance Schottky 3-STATE Bus circuits are � Advanced oxide-isolated, ion-implanted Schottky TTL designed to provide either bidirectional or unidirectional process buffer interface in Memory, Microprocessor, and Communi- � Improved switching performance with less power dissi- cation Systems. The output characteristics of the circuits pation compared with Schottky counterpart have low impedance sufficient to drive terminated trans- � Functional and pin compatible with 74LS and Schottky mission lines down to 133Ω. The input characteristics of counterpart the circuits likewise have a high impedance so it will not � Switching response specified into 500Ω and 50 pF significantly load the transmission line. The package con- � Specified to interface with CMOS at V = V − 2V tains eight 3-STATE buffers organized with four buffers OH CC having a common 3-STATE enable gate. The DM74AS240 and DM74AS244 are eight wide in a 20 pin package, and may be used as a 4 wide bidirectional or eight wide unidi- rectional. The buffer selection includes inverting and non- inverting, with enable or disable 3-STATE control.
