DescriptionThe DM74ALS273WM is designed as one kind of monolithic, positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic with a direct clear input.
DM74ALS273WM has five features. (1)Switching specifications at 50pF. (2)Switching specifications guaranteed over full temperature and Vcc range. (3)Buffer-type outputs and imporoved AC offer significant advantage over DM74LS273. (4)Advanced oxide-isolated, ion-implanted schottky TTL process. (5)Functionally and pin-for-pin compatible with DM74LS273. Those are all the main features.
Some absolute maximum ratings of DM74ALS273WM have been concluded into several points as follow. (1)Its supply voltage would be 7V. (2)Its input voltage would be 7V. (3)Its operating free-air temperature range would be from 0°C to 70°C. (4)Its storage temperature range would be from -65°C to 150°C. (5)Its typical JA would be 79°C/W. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to DM74ALS273WM.
Also some electrical characteristics of DM74ALS273WM are concluded as follow. (1)Its input clamp voltage would be max -1.5V. (2)Its high level output voltage would be min 2.4V and typ 3.3V at Ioh=-2.6mA and would be min Vcc-0.2V at Ioh=-400uA. (3)Its low level output voltage would be typ 0.25V and max 0.4V at Iol=12mA and would be typ 0.35V and max 0.5V at Iol=24mA. (4)Its input current at maximum input voltage would be max 0.1mA. (5)Its high level input current would be max 20mA. (6)Its low level input current would be max -0.2mA. (7)Its output drive current would be min -30mA and max -112mA. (8)Its supply current would be typ 11mA and max 20mA at output high and would be typ 19mA and max 29mA at output low. (9)Its maximum clock frequency would be min 35MHz. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
