Frequently Asked Questions
What is the SN74BCT245DW and what does it do?
The SN74BCT245DW is an 8-bit octal bus transceiver with 3-state outputs from Texas Instruments. It enables bidirectional data transfer between two buses, controlled by a direction pin (DIR) and output-enable pin (OE). The BCT family uses BiCMOS technology with TTL-compatible inputs and high-drive CMOS outputs, making it ideal for 5V logic bus interfacing.
What package and pin count does the SN74BCT245DW use?
The SN74BCT245DW comes in a 20-pin SOIC package. The DW suffix denotes a wide-body SOIC-20 with 1.27mm pin pitch, a standard SMD package widely supported by PCB assembly lines.
What is the operating temperature range of the SN74BCT245DW?
The SN74BCT245DW has a commercial temperature range of 0C to 70C, suitable for consumer, industrial-light, and general-purpose applications.
What are common alternatives or replacements for the SN74BCT245DW?
Pin-compatible and functionally equivalent alternatives include the SN74AHCT245DW (faster AHCT logic), SN74HCT245DW (CMOS HCT, lower power), and 74ACT245 series. The AHCT variant offers lower propagation delay and broader voltage tolerance.
Where can I buy SN74BCT245DW and what is the price?
SN74BCT245DW is available for inquiry at FindMyChip starting from $4.53 per unit (qty 1), with price breaks at $3.02 (qty 3) and $2.265 (qty 9). We support global shipping with a minimum order quantity of 1 piece.
