SN74ABTE16245DLR

Specialty Logic Overview

The SN74ABTE16245DLR is a 16-bit (dual-octal) noninverting bus transceiver featuring incident-wave switching technology and 3-state outputs. Manufactured by Texas Instruments, it operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes an SSOP-48 package and supports TTL input levels with TTL output levels. It provides a low-level output current of 64 mA and a high-level output current of -32 mA. The component functions as two 8-bit transceivers or one 16-bit transceiver, with a propagation delay of 4.2 ns. It is rated for operation between -40°C and +85°C.

Specialty Logic Feature Summary

• Incident-wave switching architecture for signal integrity
• Dual-octal configuration allowing flexible bus organization
• High drive capability with 64 mA low-level output current

Specialty Logic Applications

• High-speed data bus interfaces
• Memory bus architectures
• Parallel communication systems

Specialty Logic Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the operating temperature range of -40°C to +85°C meets the environmental specifications of the target application. Ensure compatibility with 5V logic families given the TTL input/output characteristics defined in the datasheet.

Specialty Logic Selection Notes

Select this component when incident-wave switching is required to minimize reflections on high-speed buses. Compare against standard AHCT or ALVT variants if lower power consumption or different voltage levels are needed. The 64 mA drive strength makes it suitable for driving multiple loads or longer traces compared to standard logic families.

Specialty Logic Part Context

This part belongs to the SN74ABTE series of incident-wave switching bus transceivers from Texas Instruments. It is designed to replace older generation transceivers in high-performance systems. The SSOP-48 package provides a compact footprint for dense PCB layouts while maintaining the electrical performance necessary for modern digital interfaces.

Specialty Logic Replacement Considerations

The SN74ABTH16245 is a related high-speed transceiver but lacks incident-wave switching features. Verify functional equivalence carefully, as the switching mechanism differs significantly between the ABTE and ABTH series.
