SN74BCT623N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT623N is an octal bus transceiver utilizing state-of-the-art BiCMOS design. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features dual output-enable inputs (OEAB and OEBA) for flexible asynchronous data transmission between two 8-bit buses. Electrical characteristics include a maximum low-level output current of 128 mA and high-level output current of -15 mA. Switching performance at 5 V with a 50 pF load shows propagation delays ranging from 0.5 ns to 8.3 ns.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual-directional asynchronous communication capability between A and B buses
• Flexible timing control via independent output-enable inputs
• Data storage function achieved by simultaneously enabling both output controls
• High drive strength with low quiescent current consumption

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication interfaces between data buses
• Bidirectional data buffering applications
• Bus isolation circuits requiring configurable enable states

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant, as the N suffix denotes a plastic DIP-20 housing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the required commercial temperature rating of 0°C to 70°C for the intended operational environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring bidirectional octal data transfer with independent direction control. The dual-enable architecture allows for bus holding capabilities not available in standard single-enable transceivers. Verify that the required drive current does not exceed the specified limits for the target logic family.
