SN74ALS1244AJ

The SN74ALS1244AJ is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The feature of SN74ALS1244AJ are as follows: (1)Low-Power Versions of 4ALS244 Series; (2)3-State Outputs Drive Bus Lines or Buffer Memory Address Registers; (3)pnp Inputs Reduce dc Loading; (4)Package Options Include Plastic Small-Outline (DW) Packages, Ceramic; (5)Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs.

The absolute maximum ratings of the SN74ALS1244AJ are: (1)Supply voltage, VCC: 7 V; (2)Input voltage, VI: 7 V; (3)Voltage applied to a disabled 3-state output: 5.5 V; (4)Operating free-air temperature range, TA: 0°C to 70°C; (5)Storage temperature range: 65°C to 150°C.

The following is about the electrical characteristics of SN74ALS1244AJ: (1)VIK: -1.5V max at VCC = 4.5 V, II = 18 mA; (2)VOH: VCC-2V min at VCC=4.5V to 5.5V, IOH=-0.4mA; (3)VOL: 0.25V typical and 0.4V max at VCC=4.5V, IOL=12mA; (4)IOZH: 20A max at VCC=5.5V, VO=2.7V; (5)IOZL: -20A max at VCC = 5.5 V, VO = 0.4 V; (6)II: 0.1mA max at VCC = 5.5 V, VI = 7 V; (7)IIH: 20A max at VCC = 5.5 V, VI = 2.7 V; (8)IIL: -0.1mA max at VCC = 5.5 V, VI = 0.4 V; (9)IO#: -30mA min and -112mA max at VCC = 5.5 V, VO = 2.25 V; (10)ICC: 6mA typical and 11mA max at  VCC = 5.5 V, Outputs high.
