Product Summary
The DM74LS244WM buffer/line driver is 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, the DM74LS244WM provides improved noise rejection and high fanout outputs and can be used to drive terminated lines down to 133Ω.
Parametrics
DM74LS244WM absolute maximum ratings: (1)Supply Voltage: 7V; (2)Input Voltage: 7V; (3)Operating Free Air Temperature Range: 0°C to 70°C; (4)Storage Temperature Range: -65°C to 150°C; (5)IOH High Level Output Current: -12 to 15 mA; (6)IOL Low Level Output Current : 12 to 24 mA.
Features
DM74LS244WM features: (1)TRI-STATE outputs drive bus lines directly; (2)PNP inputs reduce DC loading on bus lines; (3)Hysteresis at data inputs improves noise margins; (4)Typical IOL (sink current): 24 mA; (5)Typical IOH (source current): 15 mA; (6)Typical propagation delay times Inverting 10.5 ns, Noninverting 12 ns; (7)Typical enable/disable time 18 ns; (8)Typical power dissipation (enabled)Inverting 130 mW, Noninverting 135 mW.
