74FCT245ATPYG - Renesas Electronics

Description: The 74FCT245T octal bidirectional transceiver is designed for asynchronous two way communication between data buses. The transmit/receive (T/R) input determines the direction of data flow through the bidirectional transceiver. The 74FCT245T operates at -40C to +85C. (For Mil version, see 54FCT245T)

74FCT245ATPYG Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the 74FCT245ATPYG is 4.5V to 5.5V.
  • When the input pins are not in use, they should be tied to VCC or GND through a pull-up or pull-down resistor to prevent floating inputs and reduce power consumption.
  • The maximum frequency of operation for the 74FCT245ATPYG is 100 MHz.
  • 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 and ringing.
  • While the 74FCT245ATPYG is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage levels may not meet the required specifications, and the device may not function correctly at lower voltages.
