74CBTLV3244PGG - Renesas Electronics

Description: The 74CBTLV3244 octal bus switch has standard 244 pinouts and is designed for asynchronous communication between data buses. Sets of four switches are controlled by one output Enable (OE). When OE is low, the set of four bus switches is on and port A is connected to port B. When OE is high, the set of four bus switches is off and a high impedance exists between port A and port B. The 74CBTLV3244 operates at -40C to +85C

74CBTLV3244PGG Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the 74CBTLV3244PGG is 2.3V to 3.6V, although it can operate from 1.65V to 3.6V with reduced performance.
  • To ensure signal integrity, use a low-impedance PCB design, keep signal traces short, and use termination resistors or series resistors to reduce signal reflections. Additionally, consider using a signal integrity analysis tool to simulate and optimize your design.
  • While the 74CBTLV3244PGG can tolerate 5V input levels, it is not recommended to operate the device at 5V VCC. The device is designed for low-voltage operation, and operating it at 5V may reduce its performance and lifespan.
  • To ensure proper operation, power up the VCC pin before applying input signals, and power down the VCC pin after removing input signals. Additionally, consider using a power sequencing controller or a voltage supervisor to manage power-up and power-down sequences.
  • The 74CBTLV3244PGG can sink or source up to 24mA per output pin, although this may vary depending on the operating voltage and temperature.
