The HD74HC240FPEL-E is a high-speed CMOS octal buffer/line driver with inverted 3-state outputs from Renesas Electronics America. It features high noise immunity and low power consumption, making it ideal for a variety of applications. The device has two output enables, one for each group of four buffers. When the output enable is high, the corresponding outputs are in a high-impedance state.

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented systems
• Data transmission
• Logic buffering

Features

• High speed: tpd = 14 ns (typ.) at VCC = 5V
• Low power dissipation: ICC = 4 μA (max.) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min.)
• Output drive capability: 15 LSTTL loads
• 3-State Outputs
• Two Output Enables per four buffers
• Wide operating voltage range: 2V to 6V
• Temperature range: -40°C to +85°C
• Package: SOP-20 (Small Outline Package)

Benefits

• High-speed data transmission and signal buffering.
• Reduced power consumption compared to TTL logic.
• Improved system reliability due to high noise immunity.
• Versatile application due to wide operating voltage range.
• Increased system flexibility with 3-state outputs for bus isolation.

Additional Details

The HD74HC240FPEL-E operates with a propagation delay of approximately 14 ns at 5V. It features inverted outputs. The device can drive up to 15 LSTTL loads. The wide operating temperature range makes it suitable for harsh environments. The SOP-20 package offers a compact footprint. The output enable controls allow for selective enabling of the outputs, making it suitable for bus-oriented systems where multiple devices share the same bus lines.
