The TC74LCX07FT from Toshiba Semiconductor and Storage is a low-voltage CMOS hex buffer with open-drain outputs. This buffer is designed for high-speed, low-power operation in systems operating between 2.0V and 3.6V. The open-drain outputs allow for flexible voltage level translation and wired-OR applications.

Applications

• Voltage level translation
• Wired-OR logic functions
• Line driving with external pull-up resistors
• Interface between low-voltage and high-voltage systems
• Memory addressing

Features

• Low-voltage operation: VCC = 2.0 V to 3.6 V
• High-speed operation: tpd = 4.2 ns (max) at VCC = 3.3 V
• Low power dissipation: ICC = 10 μA (max) at Ta = 25°C
• Open-drain outputs: Requires external pull-up resistors
• Output drive capability: IOL = 24 mA (min) at VCC = 3.0 V
• TTL compatible inputs: VIH = 1.7 V (min), VIL = 0.8 V (max)
• Operating temperature range: -40 to 85°C
• Package: TSSOP (Thin Shrink Small Outline Package)

Benefits

• Flexible voltage level translation capabilities.
• Wired-OR logic implementation.
• Low power consumption for extended battery life.
• High-speed operation for improved system performance.
• Direct interface with TTL logic levels.
• Strong output drive capability for multiple loads.
• Reliable performance across a wide temperature range.

Additional Details

The TC74LCX07FT comes in a TSSOP14 package. Because of the open-drain outputs, external pull-up resistors are required to define the high-level output voltage. The value of the pull-up resistor should be chosen based on the desired speed and current consumption. The input protection circuitry prevents damage from electrostatic discharge. Its low power consumption and high speed make it suitable for portable and battery-powered applications.

The ability to implement wired-OR logic functions can reduce component count and simplify circuit design. The TTL-compatible inputs allow for seamless integration with other TTL logic devices.
