The KS74AHCT365N is a hex buffer/driver with 3-state outputs; a member of the Samsung KS74AHCT series of high-speed CMOS logic devices. This device provides six independent buffer/driver circuits with 3-state outputs, suitable for driving bus lines or multiplexing signals.

Applications

• Bus drivers
• Line drivers
• Memory address drivers
• Clock drivers

Features

• High-speed operation: tpd = 7.5 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
• Symmetrical output impedance: |IOH| = IOL = 12 mA (min)
• Balanced propagation delays: tPLH ≈ tPHL
• Wide operating voltage range: VCC = 4.5 V to 5.5 V
• ESD protection: HBM > 2000 V, MM > 200 V
• Inputs accept voltages higher than VCC

Benefits

• Improved system performance due to high-speed operation.
• Reduced power consumption leading to energy efficiency.
• Enhanced noise immunity ensuring reliable operation in noisy environments.
• Increased fan-out capability supporting more devices on the same bus.
• Simplified system design due to symmetrical output impedance.
• Enables multiplexing and bus driving applications with 3-state outputs.
• Compatibility with TTL logic levels.
• Robustness due to wide operating voltage range and ESD protection.

Additional Details

The KS74AHCT365N features six inverting buffers with 3-state outputs. Each buffer is enabled by a low level on the corresponding enable input. When the enable input is high, the output is in a high-impedance state. The device is characterized for operation over the temperature range of -40°C to +85°C.
