SN74BCT623NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT623NSR 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 from 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 low-level output currents up to 64 mA on the B port and high-level output currents up to -15 mA. Propagation delays are specified with maximum values reaching 8.3 ns depending on direction and load conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual-output enable configuration allows independent or simultaneous control of data flow between A and B buses, supporting isolation or data storage modes.
• State-of-the-art BiCMOS technology significantly reduces quiescent current consumption compared to standard logic families.
• Provides true non-inverting data transmission with tri-state outputs for effective bus isolation when disabled.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication interfaces between data buses
• High-performance bi-directional bus architectures
• Memory-to-memory or memory-to-I/O data transfers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'SR' corresponds to the SOIC package type and tape-and-reel quantity of 2000 units. Confirm the specific revision level matches the required datasheet version SCBS020A. Ensure the component meets the commercial temperature range specifications of 0°C to 70°C rather than the military grade variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring robust bi-directional data transfer with low power dissipation. The BiCMOS process offers superior drive capability while maintaining low static power. Consider the dual-enable feature if the application requires complex bus arbitration or temporary data latching without external registers.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle data storage?

Data can be stored by simultaneously enabling both OEAB and OEBA inputs. In this configuration, each output reinforces its input, keeping the bus lines at their last states if other sources are high impedance.

What is the function of the OEAB and OEBA inputs?

These dual output-enable inputs control the direction of data flow. They allow transmission from A to B, B to A, both directions simultaneously, or complete isolation of the buses.
