SN74ALS654-1NT is listed in the Buffers, Drivers, Receivers, Transceivers range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is BUS TRANSCEIVER, ALS SERIES. Review the specifications below when checking this part for your BOM.
The SN74ALS654-1NT is an octal bus transceiver and register with 3-state outputs manufactured by Texas Instruments. It belongs to the ALS logic series and features a PDIP-24 package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 14 ns, high-level output current of -5 mA, and low-level output current of 48 mA. It supports through-hole mounting and functions within an operating temperature range of 0°C to +70°C.
Verify component authenticity against Texas Instruments specifications. Confirm the PDIP-24 package type and ALS logic family designation match project requirements. Ensure operational temperature ranges align with system environmental constraints. Cross-reference datasheet revisions for any functional updates prior to final design approval.
Select this component for applications requiring octal bidirectional data transfer with registered storage. The ALS series offers improved speed over standard 74LS equivalents while maintaining compatible pinouts. Verify that the 3-state output drive capability meets the load requirements of the connected bus lines.
This part is part of the SN74ALS654 family of registered bus transceivers. It serves as a bridge between microprocessors and peripheral devices, providing both direction control and data latching. The device simplifies board layout by integrating eight bits of registration into a single package.
SN74ALS654N is a direct equivalent in the same logic family.
