Description

The SN74LS541N is designed as an octal buffer and line driver with the same functions as the LS241, but with pinouts on the opposite side of the package. This device type is designed to be used as a memory address driver, clock driver and bus-oriented transmitter/ receiver. This device is especially useful as output ports for the microprocessors, allowing ease of layout and greater PC board density.

SN74LS541N has five features. (1)Hysteresis at inputs to improve noise margin. (2)PNP inputs reduce loading. (3)3-state outputs drive bus lines. (4)Inputs and outputs opposite side of package, allowing easier interface to microprocessors. (5)Input clamp diodes limit high-speed termination effects. Those are all the main features.

Some guaranteed operating ranges of SN74LS541N 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 -15mA. (4)Its output current low level would be max 24mA.

Also some DC characteristics of SN74LS541N 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 2.4V and typ 3.4V. (5)Its output low voltage would be typ 0.25V and max 0.4V with condition of Iol=12mA and would be typ 0.35V and max 0.5V with condition of Iol=24mA. (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 -0.2mA. (8)Its short circuit current would be min -40mA and max -225mA with condition of Vcc=max. (9)Its power supply current would be max 32mA with condition of Vcc=max and output high. And so on.
