Instructions for Use

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the specified range of 2.0V to 6.0V.
    • Connect the ground (GND) pin to a stable ground reference.
  2. Input Signals:

    • Input signals should be within the valid logic levels:
      • Low: VIL ≤ 0.8V
      • High: VIH ≥ 2.0V
    • Ensure input signals are not floating; use pull-up or pull-down resistors if necessary.
  3. Output Signals:

    • The output low voltage (VOL) should be less than or equal to 0.4V when sourcing up to 16mA.
    • The output high voltage (VOH) should be greater than or equal to 2.7V when sinking up to 4mA.
  4. Propagation Delay:

    • The propagation delay time (tpd) is typically 10ns at VCC = 5V and TA = 25°C. Ensure your design accounts for this delay.
  5. Thermal Management:

    • The maximum power dissipation per package is 350mW. Ensure adequate heat dissipation if operating near this limit.
    • The operating temperature range is -40°C to 85°C. Store the device between -65°C and 150°C.
  6. Handling and Storage:

    • Handle the device with care to avoid static damage. Use proper ESD protection.
    • Store the device in a dry environment to prevent moisture damage.
  7. Pin Configuration:

    • Refer to the datasheet for the specific pin configuration and function of each pin.
  8. Application Notes:

    • The SN74HCT245N is a bidirectional 8-bit bus transceiver designed for 2V to 6V VCC operation.
    • It can be used to increase the driving capability of TTL/CMOS circuits and to isolate sections of a data bus.

For detailed specifications and additional information, refer to the official Texas Instruments datasheet for the SN74HCT245N.
