MM74HCT541N application field and working principle

The MM74HCT541N is an 8-bit buffer/line driver designed for use in memory address drivers, clock drivers, and high-performance bus-oriented systems. This device is an ideal choice for memory address and data bus drivers as its low power consumption allows for faster clock speeds with minimal current draw.

The MM74HCT541N is commonly used in applications such as:

• Bus-oriented systems in which low voltage signals need to be buffered
• PDAs and handheld computers
• Memory address drivers
• Clock drivers
• High-speed interface applications

The MM74HCT541N operates between 5V and 3V and is available in either a 16-pin DIP (dual inline package) or an 8-pin SO (small outline) package. It has tri-state outputs for maximum system flexibility. The 8-bit bus can be configured in eight individual outputs or in two 4-bit sections. It can be connected as an 8-bit or two 4-bit buses, depending on the application.

The MM74HCT541N is a dual supply logic buffer with three logic families; TTL, HC, and CMOS. The device is useful for driving high capacitive loads or multiple loads. The device is designed for optimum performance in both low and high power applications. With a low input capacitance, the device can switch data at much higher speeds than standard TTL/CMOS logic.

The MM74HCT541N works on a broad range of power supplies, from 3.6V to 5.5V, with a supply current of 14mA max at 3V and 30mA max at 5V. The device has input logic levels that correspond to the TTL logic family, with the input voltage thresholds set at 0.4V for logic \'low\', 1.4V for logic \'high\', and 1.3V for standby or tri-state voltage. The output logic levels correspond to the family of logic used (TTL, HC & CMOS).

The MM74HCT541N includes both an output enable (OE) and an active-low enable (EN) input, so that the output enable or the active low enable can be used independently, depending on the application. When OE is HIGH, the device is in a tri-state condition and all outputs are disabled. When EN is LOW, the device is enabled and the outputs are enabled. When both OE and EN are LOW, the device is also disabled.

The MM74HCT541N is a low-power, low-voltage CMOS device designed for memory address and data bus applications. With its low power consumption, tri-state outputs for maximum system flexibility and low input capacitance for high-speed operation, the device is ideal for bus-oriented systems and high-speed interface applications.
