The 74HC245PW,118 is a high-speed CMOS octal bus transceiver designed by Nexperia. It is part of the 74HC family of logic devices, which are known for their high-speed performance and low power consumption. Here’s a detailed description of its features and specifications:
General Description:
The 74HC245 is an octal transceiver that allows for bidirectional data transfer between two buses. It is particularly useful in applications where data needs to be transmitted in both directions, such as in communication between microcontrollers and peripheral devices. The device operates at high speeds, making it suitable for a variety of digital applications.
Key Features:
- Bus Transceiver: The device can transmit data in both directions, allowing for flexible communication between two buses.
- High-Speed Operation: The 74HC245 can operate at speeds up to 25 MHz, making it suitable for high-speed applications.
- Low Power Consumption: It features low power dissipation, which is beneficial for battery-operated devices.
- Wide Supply Voltage Range: The device operates with a supply voltage range of 2V to 6V, making it compatible with various logic levels.
- Tri-State Outputs: The outputs can be placed in a high-impedance state, allowing multiple devices to share the same bus without interference.
- Control Pins: The device includes control pins (DIR and OE) that determine the direction of data flow and enable or disable the outputs, respectively.
Pin Configuration:
The 74HC245 is typically available in a 20-pin Dual In-line Package (DIP) or a surface-mount package. The pin configuration includes:
- A1 to A8: Data inputs for one bus.
- B1 to B8: Data outputs for the other bus.
- DIR: Direction control pin that determines the data flow direction.
- OE: Output enable pin that controls the activation of the outputs.
Electrical Characteristics:
- Input Voltage Levels: The device recognizes standard logic levels, with a minimum high-level input voltage (VIH) of 2V and a maximum low-level input voltage (VIL) of 0.8V at a 5V supply.
- Output Drive Capability: The outputs can drive standard TTL loads, providing a high output current capability.
- Propagation Delay: The typical propagation delay is around 15 ns, ensuring fast data transfer.
Applications:
The 74HC245 is widely used in various applications, including:
- Data bus interfacing in microcontroller systems.
- Communication between different logic families.
- Memory interfacing and data buffering.
- General-purpose data transfer in digital circuits.
Package Information:
The PW suffix indicates that the device is in a TSSOP (Thin Shrink Small Outline Package) format, which is compact and suitable for space-constrained applications. The 118 designation typically refers to the specific production lot or batch.
Conclusion:
The 74HC245PW,118 from Nexperia is a versatile and efficient octal bus transceiver that provides high-speed data transfer capabilities with low power consumption. Its bidirectional functionality, tri-state outputs, and wide supply voltage range make it an ideal choice for a variety of digital communication applications.
