Frequently Asked Questions
What is the supply voltage range for the SN74HC245DWR?
The SN74HC245DWR operates over a supply voltage range of 2V to 6V, making it compatible with both 3.3V and 5V logic systems. This wide range allows flexible integration into a variety of digital circuit designs without additional level shifting.
How does the direction control work on the SN74HC245DWR?
The SN74HC245DWR uses a DIR pin to control the direction of data flow between its two 8-bit ports (A and B). When DIR is high, data flows from A to B; when DIR is low, data flows from B to A. The OE pin (active low) enables or disables all outputs, putting them into a high-impedance tri-state for bus sharing.
What package does the SN74HC245DWR use and what are its dimensions?
The SN74HC245DWR comes in a 20-pin SOIC wide body (DWR) surface-mount package. This package offers a good balance between board space efficiency and solderability, suitable for automated PCB assembly in high-volume production.
What are common applications for the SN74HC245DWR?
Common applications include bidirectional data bus buffering in microprocessor systems, memory interface expansion, I/O port multiplexing, and logic-level translation between different voltage domains. It is widely used in industrial controllers, embedded systems, and communication equipment.
Where can I buy the SN74HC245DWR and what is the price?
The SN74HC245DWR is available from authorized distributors starting at approximately $0.1285 per unit. FindMyChip offers in-stock inventory with worldwide shipping and competitive pricing for both small and large volume orders.
