SN54LS273DW

The SN54LS273DW is designed as a high-speed 8-bit register. The register SN54LS273DW consists of eight D-type flip-flops with a common clock and an asynchronous active LOW master reset. This device is supplied in a 20-pin package featuring 0.3 inch lead spacing.

SN54LS273DW has four features. (1)8-bit high speed register. (2)Parallel register. (3)Common clock and master reset. (4)Input clamp diode limit high-speed termination effects. Those are all the main features.

Some guaranteed operating ranges and absolute maximum ratings of SN54LS273DW have been concluded into several points as follow. (1)Its supply voltage would be min 4.5V and typ 5.0V and max 5.5V. (2)Its operating ambient temperature range would be min -55°C and typ 25°C and max 125°C. (3)Its output current high would be max -0.4mA. (4)Its output current low would be max 4.0mA. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SN54LS273DW are concluded as follow. (1)Its input high voltage would be min 2.0V. (2)Its input low voltage would be max 0.7V. (3)Its input clamp diode voltage would be typ -0.65V and max -1.5V. (4)Its output high voltage would be min 2.5V and typ 3.5V. (5)Its output low voltage would be typ 0.25V and max 0.4V. (6)Its input high current would be max 20uA at Vin=2.7V and would be max 0.1mA at Vin=7.0V. (7)Its input low voltage would be max -0.4mA at Vin=0.4V. (8)Its short circuit current would be min -20mA and max -100mA at Vcc=max. (9)Its power supply current would be max 27mA at Vcc=max. 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.
