Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix DLRG4 against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure the ordering information matches the specific TVSOP-48 variant required for your PCB layout. Cross-reference the manufacturer part number with distributor catalogs to avoid confusion with similar AHCT series components that may have different electrical characteristics or pin configurations.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between 5-V CMOS logic and TTL-compatible inputs is required. The AHCT series ensures full TTL compatibility while maintaining CMOS noise immunity. Consider the 9.5 ns propagation delay and 8 mA drive current for timing and load requirements. Verify that the operating temperature range of -40°C to +125°C meets the environmental specifications of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AHCT16245 family of 16-bit bus transceivers. It is designed for use in systems where bidirectional data flow is necessary between two buses operating at 5-V logic levels. The AHCT technology provides speed comparable to LS-TTL but with lower power consumption typical of CMOS devices, making it suitable for battery-powered or low-power applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct replacements such as the SN74AHCT16245DGVR or other variants within the same AHCT16245 family that offer compatible electrical performance and pinout. Ensure any substitute maintains the 4.5-V to 5.5-V supply voltage range and TVSOP-48 package dimensions for mechanical interchangeability.
