The MN74HC368 is a high-speed silicon-gate CMOS device featuring hex inverting bus drivers with three-state outputs. These drivers are designed for use in bus-oriented applications where data can be driven onto or off the bus. The three-state outputs allow multiple devices to share the same bus lines, enabling efficient data transfer and reduced component count.

Applications

• Memory addressing and data bus systems
• Microprocessor and microcontroller interfaces
• Logic level conversion
• Line driving and buffering
• Digital data transmission

Features

• High-speed operation: tpd = 13ns (typ.) at VCC = 5V
• Three-state outputs for bus-oriented applications
• Low power dissipation: ICC = 4μA (max.) at VCC = 5V
• Wide operating voltage range: VCC = 2V to 6V
• High noise immunity: NIL = 30% VCC, NIH = 70% VCC
• Fanout of 15 LS-TTL loads
• Operating temperature range: -40°C to +85°C

Additional Details

The MN74HC368 is characterized for operation from -40°C to +85°C. The three-state outputs are controlled by an output enable (OE) input. When OE is low, the outputs are enabled, and the device functions as a standard hex inverter. When OE is high, the outputs are disabled and enter a high-impedance state, allowing other devices to drive the bus lines. The device is available in various package options, including DIP and SOIC, to accommodate different board layouts and assembly requirements. The high noise immunity and low power dissipation make the MN74HC368 suitable for use in a wide range of digital logic applications. Its high-speed performance ensures that it can keep pace with modern microprocessors and microcontrollers. The device is compatible with other 74HC series logic devices, simplifying system integration.
