SN54ALS273FK

The SN54ALS273FK is designed as one kind of octal positive-edge-trigged flip-flops utilize TTL circuitry to implement D-type flip-flop logic with a direct-clear input.

SN54ALS273FK has five features. (1)Contain eight flip-flops with single-rail outputs. (2)Buffered clock and direct-clear inputs. (3)Individual data input to each flip-flop. (4)Applications include buffer/storage registers, shift registers, pattern generators. (5)Package options is ceramic chip carriers (FK). Those are all the main features.

Some absolute maximum ratings of SN54ALS273FK 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 fom -55°C to 125°C. (4)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SN54ALS273FK are concluded as follow. (1)Its Vik would be max -1.5V with conditions of Vcc=4.5V and Ii=-18mA. (2)Its output voltage high would be min Vcc-0.2V at Vcc=4.5V to 5.5V and Ioh=-0.4mA and it would be min 2.4V and typ 3.3V at Vcc=4.5V and Ioh=-1mA. (3)Its output voltage low would be typ 0.25V and max 0.4V at Vcc=4.5V and Iol=12mA. (4)Its input current would be max 0.1mA. (5)Its Iih would be max 20uA with conditions of Vcc=5.5V and Vi=2.7V. (6)Its Iil would be max -0.2mA with conditions of Vcc=5.5V and Vi=0.4V. (7)Its output current would be min -20mA and max -112mA with conditions of Vcc=5.5V and Vo=2.25V. (8)Its Icch would be typ 11mA and max 20mA at Vcc=5.5V. (9)Its Iccl would be typ 19mA and max 29mA at cc=5.5V. 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.
