Product Summary

The SN74LS244N is an octal buffer and line driver. The SN74LS244N is designed specifically to improve both the performance and density of three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The designer has a choice of selected combinations of inverting and noninverting outputs, symmetrical, active-low output-control (G) inputs, and complementary output-control (G and G) inputs. The SN74LS244N features high fan-out, improved fan-in, and 400-mV noise margin. The device can be used to drive terminated lines down to 133 Ω.

Parametrics

SN74LS244N absolute maximum ratings: (1)Supply voltage, VCC: 7 V; (2)Input voltage, VI: 7 V; (3)Off-state output voltage: 5.5 V; (4)Package thermal impedance, θJA: 69℃/W; (5)Storage temperature range, Tstg : -65 to 150℃.

Features

SN74LS244N features: (1)3-State Outputs Drive Bus Lines or Buffer Memory Address Registers; (2)PNP Inputs Reduce DC Loading; (3)Hysteresis at Inputs Improves Noise Margins.
