DM74LS240, DM74LS241 Octal 3-STATE Buffers/Line Drivers/Line Receivers March 1998 DM74LS240, DM74LS241 Octal 3-STATE Buffers/Line Drivers/Line Receivers General Description n Typical IOL (sink current) 54LS 12 mA These buffers/line drivers are designed to improve both the 74LS 24 mA performance and PC board density of 3-STATE buffers/ n Typical IOH (source current) drivers employed as memory-address drivers, clock drivers, 54LS -12 mA and bus-oriented transmitters/receivers. Featuring 400 mV 74LS -15 mA of hysteresis at each low current PNP data line input, they n Typical propagation delay times provide improved noise rejection and high fanout outputs Inverting 10.5 ns and can be used to drive terminated lines down to 133. Noninverting 12 ns n Typical enable/disable time 18 ns Features n Typical power dissipation (enabled) n 3-STATE outputs drive bus lines directly Inverting 130 mW n PNP inputs reduce DC loading on bus lines Noninverting 135 mW n Hysteresis at data inputs improves noise margins Connection Diagrams Dual-In-Line Package Dual-In-Line Package DS006411-1 DS006411-2 Order Number DM54LS240J, DM54LS240W, DM54LS240E, Order Number DM54LS241J, DM74LS240WM or DM74LS240N DM54LS241W, DM54LS241E, See Package Number E20A, J20A, DM74LS241WM or DM74LS241N M20B, N20A or W20A See Package Number E20A, J20A, M20B, N20A or W20A
