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 us.
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 Noninverting 10.5 ns 12 ns 18 ns s Typical enable/disable time Inverting Noninverting 130 mW 135 mW s Typical power dissipation (enabled) Ordering Code: Order Number DM74LS244WM DM74LS244SJ DM74LS244N Package Number M20B M20D N20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 20-Lead Small Out.
