74LS240 - Octal 3-STATE Buffer/Line Driver/Line Receiver

General Description

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.

Key Features

  • s 3-STATE outputs drive bus lines directly s PNP inputs reduce DC loading on bus lines s Hysteresis at data inputs improves noise margins s Typical IOL (sink current) 24 mA s Typical IOH (source current).
  • 15 mA s Typical propagation delay times Inverting 10.5 ns Noninverting 12 ns s Typical enable/disable time 18 ns s Typical power dissipation (enabled) Inverting 130 mW Noninverting 135 mW Ordering Code: Order Number Package Number Package.

DM74LS240 • DM74LS241 Octal 3-STATE Buffer/Line Driver/Line Receiver August 1986 Revised March 2000 DM74LS240 • DM74LS241 Octal 3-STATE Buffer/Line Driver/Line Receiver General Description 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 improved noise rejection and high fanout outputs and can be used to drive terminated lines down to 133Ω.
