The TC74HC368AF is a Hex Inverting Buffer/Line Driver with 3-State Outputs from Toshiba's TC74HC series of high-speed CMOS logic devices. This integrated circuit (IC) contains six independent inverting buffer/line drivers, each with a 3-state output, but unlike the TC74HC366AF, its pins are arranged with two separate enable pins controlling three inverting buffers each. The 3-state outputs allow the device to be connected directly to a bus, enabling multiple devices to share the same line. Each buffer inverts the input signal. It operates with a wide range of supply voltages and offers low power consumption.

Applications

• Memory addressing (inverted): Used to drive memory address lines with inverted logic, especially where grouped enables are useful.
• Data bus driving (inverted): Employed as a bus driver to increase signal strength with signal inversion, with grouped enables offering control.
• Peripheral interfacing (inverted): Utilized for connecting peripherals to a microcontroller or microprocessor with signal inversion, benefiting from grouped enables.
• Logic level translation (inverted): Can be used to translate logic levels between different systems with signal inversion.
• Data transmission (inverted): Integrated within data transmission systems requiring signal inversion.

Features

• High-speed operation: Offers fast signal propagation due to its high-speed CMOS technology.
• Wide operating voltage range: Functions across a broad voltage spectrum, enhancing compatibility.
• Low power consumption: Minimizes energy usage.
• Hex inverting buffer/line driver: Provides six independent inverting buffers/line drivers.
• 3-State outputs: Allows outputs to be in a high, low, or high-impedance state.
• CMOS technology: Ensures excellent noise immunity and stable operation.
• Two Enable Pins: The six buffers are controlled by two separate enable pins, three buffers each.

Benefits

• Improved bus performance: The 3-state outputs enable efficient sharing of a bus.
• Increased signal strength: Line drivers enhance signal integrity over long distances.
• Simplified circuit design: Reduces the number of components required for bus interfacing.
• Energy efficiency: Low power consumption translates to lower operating costs.
• Enhanced reliability: CMOS technology provides stable performance.
• Flexible Enable Control: The two enable pins allow for more granular control of the buffers.
