SN74AS245NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS245NS is an octal bus transceiver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum propagation delay of 5.5 ns at 5 V. The device utilizes PNP inputs to reduce DC loading and supports bidirectional data transmission between two buses based on the logic level at the direction-control (DIR) input. It is housed in a 20-pin Small Outline Package (SOP/NS).

Buffers, Drivers, Receivers, Transceivers Feature Summary

Provides asynchronous two-way communication between data buses.
Features 3-state outputs that drive bus lines directly.
Utilizes PNP inputs to minimize DC loading.

Buffers, Drivers, Receivers, Transceivers Applications

Asynchronous two-way communication between data buses.
Bus-oriented memory and command decoders.
High-speed data transfer applications requiring low loading.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'NS' corresponds to the SOP package and tape-and-reel carrier when sourcing. Confirm RoHS compliance status and lead finish details via the latest TI Package Option Addendum, as manufacturing parameters may change without notice. Ensure compatibility with standard SOP land patterns during PCB design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed bus interfacing with reduced input loading compared to standard TTL families. Verify that the operating temperature range of 0°C to 70°C meets system requirements. Ensure unused inputs are tied to VCC or GND to maintain proper operation and prevent floating states.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AS245 series of octal bus transceivers. It shares functional similarities with the SN74ALS245A but offers faster switching characteristics. The device is designed for general-purpose digital systems requiring reliable bidirectional data flow control across multiple parallel lines.
