Instructions for SN74HC245NSR
Power Supply:
- Ensure the supply voltage (VCC) is within the range of 2.0 V to 6.0 V.
- Connect the ground (GND) pin to the system ground.
Input Signals:
- The input signals should be within the valid logic levels:
- High: VIH ≥ 3.15 V (for VCC = 5 V)
- Low: VIL ≤ 0.85 V (for VCC = 5 V)
- Avoid applying voltages outside the specified range to prevent damage.
- The input signals should be within the valid logic levels:
Output Signals:
- The output signals will be:
- High: VOH ≥ VCC - 0.2 V
- Low: VOL ≤ 0.2 V
- Ensure the load connected to the outputs does not exceed the maximum current ratings.
- The output signals will be:
Direction Control:
- Use the direction control pins (DIR) to set the direction of data transfer:
- DIR = 0: Data transfers from A to B
- DIR = 1: Data transfers from B to A
- Use the direction control pins (DIR) to set the direction of data transfer:
Enable Control:
- Use the enable pins (OE) to control the output state:
- OE = 0: Outputs are active
- OE = 1: Outputs are high-impedance (tristate)
- Use the enable pins (OE) to control the output state:
Propagation Delay:
- The propagation delay time (tpd) is typically between 6 ns and 14 ns at VCC = 4.5 V and fo = 10 MHz. Ensure your system timing accounts for this delay.
Temperature Considerations:
- Operate the device within the temperature range of -40°C to 85°C.
- Store the device in a temperature range of -65°C to 150°C.
Handling:
- Handle the device with care to avoid electrostatic discharge (ESD) damage.
- Follow proper ESD precautions when handling and soldering the device.
Mounting:
- Ensure proper mounting and soldering techniques to avoid mechanical stress on the device.
- Use appropriate thermal management techniques if operating at high power levels or in high-temperature environments.
Testing:
- Test the device under the specified conditions to ensure it meets the required performance parameters.
- Verify the functionality using a known good test setup before integrating into a larger system.
