74LS244 Octal 3-State Buffer/Line Driver IC (74244 IC) DIP-20 Package

The 74LS244 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 fan-out outputs and can be used to drive terminated lines down to 133Ω.

Features:-

• 3-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) 24 mA

• Typical IOH (source current) −15 mA

• Typical propagation delay times Inverting 10.5 ns Noninverting 12 ns

• Typical enable/disable time 18 ns

• Typical power dissipation (enabled) Inverting 130 mW Noninverting 135 mW
