SN74ABT623NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT623NSR is an octal bus transceiver from the Texas Instruments ABT logic family, housed in a 20-pin TSSOP package. It features tri-state outputs and non-inverting polarity with eight channels. The device operates within a supply voltage range of 4.5 V to 5.5 V, supporting TTL input and output levels. Key electrical parameters include a propagation delay of 4.6 ns, low-level output current of 64 mA, and high-level output current of -32 mA. Maximum power supply current is 30 mA, and it functions reliably between -40°C and +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bus transceiver architecture providing bidirectional data transfer across eight independent channels
• Tri-state outputs enable effective bus line management and isolation when disabled
• Non-inverting signal polarity maintains original data directionality during transmission

• High-speed data routing on system buses
• Buffering memory address and data lines
• Driving capacitive loads in digital communication interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'NSR' corresponds to the TSSOP-20 surface-mount package and tape-and-reel orientation. Confirm that the ABT series designation matches the required BiCMOS performance characteristics for your circuit design. Ensure compatibility with 4.5V to 5.5V power domains before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal configuration with tri-state control is required for 5V logic systems. The ABT technology offers faster switching speeds compared to standard HC or HCT families. Consider the TSSOP-20 footprint constraints and ensure thermal management aligns with the specified operating temperature range for industrial applications.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABT623 series of octal bus transceivers manufactured by Texas Instruments. It shares functional similarities with other ABT devices but is distinct due to its specific pinout and non-inverting nature. The NSR variant specifically denotes the surface-mount packaging format suitable for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes may include other SN74ABT623 variants with different packaging options such as SN74ABT623N (PDIP) or SN74ABT623DBR (SSOP). Verify pin compatibility and electrical specifications before swapping packages.
