SN74LVC4245APWR

SN74LVC4245APWR is an octal bus transceiver and 3-state output 3.3V to 5V shifter manufactured by Texas Instruments (TI). It is designed for asynchronous communication between data buses. This device transfers data from bus A to bus B, or from bus B to bus A, depending on the logic level of the direction control (DIR) input. The output enable input can be used to disable the device, effectively isolating the buses. The control circuitry is powered by VCCA.

Key features and specifications of SN74LVC4245APWR include:

• Package Type: TSSOP-24, which is a thin small outline package known for its good heat dissipation and compact size.
• Operating Temperature Range: -40°C to +85°C, making it suitable for a wide range of environmental temperature conditions.
• Logic Levels: LVTTL compatible.
• Voltage Translation: Capable of translating between 3.3V and 5V levels, allowing communication between devices operating at different voltage standards.
• 3-State Outputs: The outputs can be high, low, or high-impedance (off state), ensuring that the IC does not interfere with other signals on the bus when not transmitting data.
• Power Supply Voltage: Minimum 2.7V (4.5V for 5V operation) and maximum 3.6V (5.5V for 5V operation).
• Propagation Delay Time: 6.7 nanoseconds, which is a measure of how quickly the device responds to changes in input signals.
• Channel Number: 8 channels, providing multiple data paths for communication.
• ESD Protection: Exceeds JESD 22 standards, providing protection against electrostatic discharge.

SN74LVC4245APWR is commonly used in interface circuit design, such as for level shifting and data communication between microprocessor or microcontroller systems and peripherals. It finds applications in communications equipment, industrial control systems, and consumer electronics products.

In summary, SN74LVC4245APWR is a versatile and reliable bus transceiver that enables seamless communication between devices operating at different voltage levels.
