DM74S244, DM74S240, (DM74S240 - DM74S244) Octal 3-STATE Buffer/Line Driver/Line Receiver
These buffers/line drivers are designed to improve both the performance and PC board density of 3-STATE buffers/ drivers employed as memory-address drivers, clock drivers, and bus-oriented transmitters/receivers.
Featuring 400 mV of hysteresis at each low current PNP data line input, they provide im
