SN74F245NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F245NS is an octal bus transceiver with 3-state outputs from the Texas Instruments F logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. The device features a propagation delay of up to 7 ns at 5 V. It provides a low-level output current of 64 mA and a high-level output current of -15 mA. The component is housed in a 20-pin SOIC package and is rated for operation between 0°C and +70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Asynchronous bidirectional data transmission between two 8-bit buses controlled by DIR and OE inputs
• High-drive 3-state outputs capable of directly driving bus lines or multiple loads
• Non-inverting logic polarity for straightforward signal routing

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base model number covers multiple variants including DIP, SSOP, and SOIC. Confirm the temperature grade corresponds to the intended operating environment. Ensure the RoHS status aligns with manufacturing compliance requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high drive strength is necessary for direct bus interfacing. The F logic series offers faster switching speeds compared to standard HC or HCT families. Consider the 20-pin SOIC footprint constraints during PCB layout planning. Evaluate power consumption against system thermal limits given the higher static currents typical of F-series devices.
