Frequently Asked Questions
What is the SN74BCT623N and what are its key electrical specifications?
The SN74BCT623N is an octal bus transceiver from Texas Instruments' BCT logic family. It features 3-state outputs, bidirectional data flow with independent control, a sink current (IOL) of 24mA at VOL=0.5V, source current (IOH) of 3mA at VOH=2.4V, and a rated load capacitance of 50pF. It is housed in a 20-pin DIP package (R-PDIP-T20).
What applications is the SN74BCT623N best suited for?
The SN74BCT623N is ideal for microprocessor bus interfaces, memory expansion, and backplane data routing where bidirectional data transfer between two buses is required. Its high-drive outputs and 3-state capability make it well-suited for industrial control, embedded systems, and communication interface buffering applications.
How does the SN74BCT623N differ from standard 74BCT245 or similar transceivers?
The SN74BCT623N features independent direction control for each port (Port A and Port B), unlike the 74BCT245 which uses a single shared direction-control pin. This makes the 623N more flexible for systems requiring asymmetric or independently managed bidirectional bus communication.
What is the package type and where can I buy the SN74BCT623N?
The SN74BCT623N comes in a 20-pin through-hole DIP package (JESD-30 code: R-PDIP-T20), making it easy to use in prototyping and production boards. It is priced from $1.66 and is available in stock with worldwide shipping through FindMyChip and authorized distributors.
