SN74F245NG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F245NG4 is an octal bus transceiver manufactured by Texas Instruments, belonging to the SN74F logic family. It features a 20-pin PDIP package and supports tri-state outputs for effective bus management. The device operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL input levels. Key electrical specifications include a propagation delay of 7 ns, a low-level output current capability of 64 mA, and a high-level output current of -15 mA. It is designed for operation in temperatures ranging from 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission across eight channels with non-inverting polarity.
• Features tri-state outputs to isolate the bus when not actively driving signals.
• Supports standard TTL input and output voltage levels for compatibility.

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional data bus communication between microprocessors and memory modules.
• Driving bus lines in digital logic systems requiring high current drive capabilities.
• Isolating data paths in computer architecture and industrial control interfaces.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the component matches the specified PDIP-20 through-hole package configuration. Confirm the manufacturer is Texas Instruments and the series is SN74F. Ensure the operating temperature range meets the application requirements of 0°C to +70°C. Check for RoHS compliance status as indicated in official documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal bus transceiver with through-hole mounting is required. The SN74F series offers faster switching speeds compared to standard 74LS counterparts. Consider the 64 mA low-level output current if driving heavy capacitive loads on the bus. Ensure the system voltage remains within the 4.5 V to 5.5 V operational window.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74F245 family of octal bus transceivers. It serves as a functional equivalent to other industry-standard octal transceivers but utilizes the specific F-series logic technology for improved performance. The 'G4' suffix typically denotes Green/RoHS-compliant manufacturing variations within the product line.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include SN74F245N and SN74F245NSR. Verify pinout compatibility and electrical characteristics before substitution. The SN74F245DW is a surface-mount alternative with identical logical functions but requires different PCB layout considerations.
