MC74HCT541 is an 8-bit buffer/line driver and open collector buffer driver series. It is a hex buffer, which features their high-impedance outputs and input common-mode voltage range that extends to the negative supply. Its typical application field can be classified under logic, featuring as a general purpose buffer, line driver, and open collector buffer driver for high-speed logic or bus driving. It can also act like a bus transceiver for 8085 parallel input/output ports and 8285 address/data selectors, as well as a control transfer and data transfer from one processor to the other. Apart from that, the buffer series can also be used to increase drive capability of low-power drivers.

The typical working principle of the MC74HCT541 buffer series is by transferring logic levels, that is, maintaining output logic level with minimum amount of power dissipation. This is applicable in applications such as switching between voltage levels, latching signals, and as a simple logic gate, such as a buffer in a logic circuit. The device is also designed with two series, the non-inverting and inverting outputs, and with the set up of active low operation, it prevents current leakage. It also features a Schmitt Trigger with transfers into TTL logic levels. The Schmitt Trigger helps to increase the noise immunity that is required in digital systems.

The MC74HCT541 buffer series can also be used in multiplexers, data selectors, signal gating, signal routing, and level conversion. It can also be used to increase signal strength and driving capability of low power applications. It is packaged in a DIP, SOIC or SO packages.

The MC74HCT541 chip is available as a monolithic integrated circuit in DIP, SOIC or SO packages. It is typically specified for operation over a wide range of temperature from - 40 degrees Celsius (- 40 Fahrenheit) to +85 degrees Celsius (+ 185 Fahrenheit) and at the open-circuit input voltage range from - 0.5V to VCC + 0.5V. The output current ratings of the chip vary in different applications and it is typically specified as 8 mA output current.

MC74HCT541 could be used in many applications like latching, signal routing, signal gating, and multiplexers, data selectors, etc. Additionally, it has different pin for input, output, or output enable. Output enable pins are called OE_, active high and active low distinguishing from the rest of the pins in the application. A logic high is established in the OE_ pin in order to turn off the output buffers and avoid power consumption.

In summary, MC74HCT541 belongs to Buffers, Drivers, and Transceivers family of logic. It is an 8-bit buffer/line driver and open collector buffer driver series. Its typical application field encompasses latching signals, switching between voltage levels and acting as a logic gate. It can operate at low power consumption and holds the input logic level with minimal amount of power dissipation. The chip is packaged in a DIP, SOIC or SO package, and typically works over a wide temperature range of - 40 to +85 Celsius. The output current ratings of the chip vary in different applications.
