General Description

These buffers/line drivers are designed to improve both the performance and PC board density of TRI-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 133 Ohm.

Features

  • TRI-STATE outputs drive bus lines directly
  • PNP inputs reduce DC loading on bus lines
  • Hysteresis at data inputs improves noise margins
  • Typical IOL (sink current) 54LS 12 mA 74LS 24 mA
  • Typical IOH (source current) 54LS -12 mA 74LS -15 mA
  • Typical propagation delay times Inverting 10.5 ns Noninverting12 ns
  • Typical enable/disable time 18 ns
  • Typical power dissipation (enabled) Inverting130 mW Noninverting135 mW
