SN74AHCT16541DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AHCT16541DL is a 16-bit buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes the AHCT logic series for TTL-voltage compatible inputs. The device is housed in a 48-pin SSOP package. Key electrical characteristics include a high-level output current of -8 mA and a low-level output current of 8 mA. It functions reliably across an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides 16-bit buffering with non-inverting logic functionality
• Features three-state outputs for bus-oriented systems
• Ensures compatibility with TTL voltage levels through AHCT input structure

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffered oscillators
• Capacitively loaded outputs and driving bus lines

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DL' indicates the 48-lead SSOP package variant when ordering. Confirm that the AHCT designation is required for TTL compatibility rather than standard AHC. Ensure the operating temperature grade matches the application environment, as this part is rated for industrial temperatures up to 85°C. Cross-reference the manufacturer part number directly with official Texas Instruments documentation to avoid counterfeit components.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide data path requires buffering with high drive capability. The AHCT family is preferred over AHC when interfacing directly with legacy TTL logic families without level shifting. Consider the SSOP package constraints regarding thermal dissipation and board space. Verify that the 4.5V to 5.5V supply range aligns with the system power architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus Family, designed for high-density digital applications. It is part of the broader SN74AHCT series, which combines the speed of CMOS technology with the input compatibility of TTL standards. The 16-bit configuration reduces component count compared to using multiple 8-bit buffers in parallel.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74AHCT16244DLR is a similar 16-bit buffer/driver in the same package but may differ in specific internal timing or drive characteristics. Verify pinout compatibility and electrical specifications before substitution. Other members of the Widebus family should be checked for functional equivalence.
