The TC74LVX240F(F) is an octal buffer/line driver with 3-state outputs from Toshiba Semiconductor and Storage. It's part of the LVX family, known for its low voltage operation and high speed. This device is designed for applications requiring high-performance buffering or driving of bus lines.

Applications

• Memory address drivers
• Clock drivers
• System bus drivers
• Data transmission
• Backplane driving
• Isolation of memory from the system bus

Features

• High-speed operation: tpd = 4.8 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 μA (max) at VCC = 5.5 V
• Output drive capability: 12 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL = 12 mA (min)
• Balanced propagation delays: tPLH ≈ tPHL
• Wide operating voltage range: VCC = 2 V to 5.5 V
• Inputs and outputs on opposite sides of the package allowing easy PCB layout

Benefits

• Facilitates high-speed data transfer and processing.
• Minimizes power consumption in portable and energy-sensitive applications.
• Provides strong drive capability for driving multiple loads or long bus lines.
• Ensures consistent signal timing and minimizes skew.
• Offers versatility in various voltage environments.
• Simplifies PCB design and reduces signal noise.

Additional Details

The TC74LVX240F(F) is an octal buffer with non-inverting 3-state outputs. Two active-low enable inputs (OE1 and OE2) control the outputs. When either OE1 or OE2 is high, the outputs are in the high-impedance state. This allows multiple devices to share a common bus. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
