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 m V 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.
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 m A s Typical IOH (source current)
- 15 m A s Typical propagation delay times Inverting Noninverting 10.5 ns 12 ns 18 ns s Typical enable/disable time Inverting Noninverting 130 m W 135 m W s Typical power dissipation (enabled)
