The TC74VHC240FK is a high-speed CMOS octal buffer/line driver with 3-state outputs, fabricated with silicon gate CMOS technology. It achieves high-speed operation while maintaining CMOS low power dissipation. This device is designed for driving bus lines and high-capacitive loads.
Applications:
- Bus driving
- Memory interfacing
- Address decoding
- Line driving
- High-capacitive load driving
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
- Operating voltage range: VCC = 2 V to 5.5 V
- Output drive capability: IO = ±8 mA (min.) at VCC = 4.5 V
- TTL compatible input thresholds
- Package: SO20
- 3-State Outputs
Benefits:
- High Speed: Enables rapid data transfer and signal propagation in bus-oriented systems.
- Low Power: Minimizes energy consumption, suitable for power-sensitive applications.
- Wide Voltage Range: Operates effectively within a wide supply voltage range, providing design flexibility.
- Strong Output Drive: Drives heavily loaded bus lines and high-capacitive loads effectively.
- 3-State Outputs: Allows multiple devices to share the same bus without contention.
The TC74VHC240FK consists of two groups of four buffers/line drivers with separate enable inputs. When the output enable (OE) input is LOW, the outputs are enabled and follow the inputs. When OE is HIGH, the outputs are in the high-impedance state. The device operates with a supply voltage range of 2V to 5.5V and features TTL-compatible input thresholds. It is packaged in an SO20 package.
The device is RoHS compliant.
