SN74ABTE16245DL

Specialty Logic Overview

The SN74ABTE16245DL is a high-performance, 16-bit bus transceiver designed for incident-wave switching applications. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input and output levels. The device provides a propagation delay of 4.2 ns, with low-level output current capability of 64 mA and high-level output current of -32 mA. It is housed in a 48-pin SSOP package and supports an operating temperature range from -40°C to +85°C.

Specialty Logic Feature Summary

• Designed specifically for incident-wave switching applications to ensure signal integrity at high speeds.
• Configurable as two independent 8-bit transceivers or a single 16-bit transceiver.
• Features non-inverting logic with tri-state outputs for effective bus management.

Specialty Logic Applications

• High-speed data transmission systems requiring incident-wave switching.
• Parallel data buses in computing and communication equipment.
• Memory interface circuits utilizing 16-bit wide data paths.

Specialty Logic Procurement Notes

Verify the specific suffix 'DL' corresponds to the SSOP-48 tube packaging configuration. Confirm that the application environment remains within the specified 4.5 V to 5.5 V power supply limits. Ensure thermal management aligns with the -40°C to +85°C operational range. Cross-reference the datasheet for clamp-current ratings if negative voltage excursions are possible on I/O lines.

Specialty Logic Selection Notes

Select this component when incident-wave switching performance is required rather than standard termination methods. Compare against the SN74ABTH16245 series if standard bus driving is sufficient, noting the functional difference in switching topology. Ensure the 48-pin SSOP footprint matches the PCB layout constraints. Verify compatibility with TTL logic levels for both inputs and outputs.

Specialty Logic Part Context

This part belongs to the Texas Instruments ABTE series, specialized for incident-wave switching. It complements the ABTH series by offering distinct signal integrity solutions for high-speed parallel interfaces. The 16-bit width allows for efficient data throughput in wide-bus architectures.

Specialty Logic Replacement Considerations

The SN74ABTE16245DLR is the reel-based variant of the same functional device. The SN74ABTH16245DL offers similar electrical characteristics but lacks incident-wave switching capabilities. Verify pinout compatibility before substituting with other 16-bit transceivers.
