Description

The SN74LS298N is designed as a quad 2-port register. It is the logical equivalent of a quad 2-input multiplexer followed by a quad 4-bit edge-triggered register.

SN74LS298N has four features. (1)Select from two data sources. (2)Fully edge-triggered operation. (3)Typical power dissipation of 65mW. (4)Input clamp diodes limit high speed termination effects. Those are all the main features.

Some guaranteed operating ranges SN74LS298N have been concluded into several points as follow. (1)Its supply voltage range would be min 4.75V and typ 5.0V and max 5.25V. (2)Its operating ambient temperature range would be min 0°C and typ 25°C and max 70°C. (3)Its output current high level would be max -0.4mA. (4)Its output current low level would be max 8mA.

Also some DC characteristics SN74LS298N are concluded as follow. (1)Its input high voltage would be min 2.0V with conditions of guaranteed input high voltage for all inputs. (2)Its input low voltage would be max 0.8V with conditions of guaranteed input low voltage for all inputs. (3)Its input clamp diode voltage would be typ -0.65V and max -1.5V with condition of Vcc=min, Iin=-18mA. (4)Its output high voltage would be min 2.7V and typ 3.5V. (5)Its output low voltage would be typ 0.25V and max 0.4V with condition of Iol=4mA. (6)Its input high current would be max 20uA with condition of Vcc=max and Vin=2.7V and it would be max 0.1mA with condition of Vcc=max and Vin=7.0V. (7)Its input low current would be max -0.4mA. (8)Its short circuit current would be min -20mA and max -100mA with condition of Vcc=max. (9)Its power supply current would be max 21mA with condition of Vcc=max.

And some AC characteristics SN74LS298N are concluded into several points as follow. (1)Its propagation delay, clock to output would be typ 18ns and max 27ns. (2)Its clock pulse width would be min 20ns. (3)Its data setup time would be min 15ns. And so on. If you have any question or suggestion or want to know more information please contact us for details.
