The KS74AHCT273N is an octal D-type flip-flop with clear; a member of the Samsung KS74AHCT series of high-speed CMOS logic devices. This device is designed for use in high-performance digital systems requiring reliable data storage and transfer.

Applications

• Registers
• Memory address drivers
• Clocked data registers
• Buffer registers

Features

• High-speed operation: tpd = 6.5 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.
• Compatibility with TTL logic levels.
• Robustness due to wide operating voltage range and ESD protection.

Additional Details

The KS74AHCT273N features eight D-type flip-flops with a common clock and clear input. Data is transferred to the outputs on the positive-going edge of the clock pulse. A low level on the clear input sets all outputs to a low state. The device is characterized for operation over the temperature range of -40°C to +85°C.
