74ABT16245BDL,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT16245BDL,118 is a 16-bit bus transceiver with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V and supports BiCMOS technology for high-speed performance. The device features two output enables (1OE and 2OE) and two direction control inputs (1DIR and 2DIR). It provides an output capability of +64 mA and -32 mA. Propagation delays are specified from 1.0 ns to 4.0 ns depending on the transition type. The component includes IOFF circuitry for partial power-down applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features IOFF circuitry that disables outputs to prevent damaging backflow currents during partial power-down conditions.
• Supports live insertion and extraction operations without causing system interference.
• Provides robust latch-up protection exceeding 500 mA per JESD 78 Class II Level B standards.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down mode operation
• Live insertion/extraction systems
• High-speed bidirectional bus interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package designation carefully as the datasheet revision history indicates the removal of the BDL (SSOP48) type number in version 6. Confirm current availability and exact package configuration directly with the manufacturer or authorized distributors before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring 16-bit data transfer at 5V logic levels. Ensure the design accommodates the specific output drive strengths of +64 mA and -32 mA. Verify that the operating temperature range of -40 °C to +85 °C meets the environmental requirements of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT16245B family of 16-bit bus transceivers. The ABT series utilizes BiCMOS technology to achieve high switching speeds while maintaining low power consumption. The device is designed to interface directly with TTL level signals, facilitating compatibility with various digital logic families in complex electronic systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for the 74ABT16245BDGG variant if the SSOP48 package is unavailable, as the original BDL package was removed from the product specification in later revisions.
