SN74ABT16500BDLR

Universal Bus Functions Overview

The SN74ABT16500BDLR is an 18-bit universal bus transceiver from Texas Instruments' 74ABT series, housed in a 56-pin SSOP package. It operates on a supply voltage range of 4.5 V to 5.5 V with a maximum propagation delay of 4.5 ns at 50 pF load. The device features three-state outputs and supports non-inverting data flow between ports A and B. It functions within a temperature range of -40 °C to +85 °C.

Universal Bus Functions Feature Summary

• Supports 18-bit bidirectional data transfer with independent control for each direction
• Features complementary output enable signals (OEAB and OEBA) for flexible bus management
• Provides tri-state outputs to prevent bus contention during inactive states

Universal Bus Functions Applications

• High-speed memory interface circuits
• Data acquisition systems requiring wide bus width
• Industrial control networks with multiple I/O channels

Universal Bus Functions Procurement Notes

Verify the specific suffix 'BDLR' corresponds to the SSOP-56 package and tape-and-reel shipping configuration. Confirm that the component meets RoHS compliance requirements as indicated in official documentation. Ensure the operating voltage range aligns with the system's power supply specifications before integration.

Universal Bus Functions Selection Notes

Select this component when an 18-bit wide bus interface is required with low propagation delay characteristics. The ABT technology offers improved speed compared to standard CMOS logic while maintaining compatibility with TTL input levels. Consider the SSOP-56 footprint constraints and thermal dissipation capabilities for the target PCB layout design.

Universal Bus Functions Part Context

This device belongs to the SN74ABT16500B family of universal bus transceivers. It is designed for high-density applications where space efficiency and signal integrity are critical. The part integrates advanced BiCMOS technology to achieve fast switching speeds and low power consumption relative to older logic families.

Universal Bus Functions Replacement Considerations

Check for direct pin-compatible alternatives within the same 74ABT series. Verify if other manufacturers offer equivalent 18-bit transceivers with matching electrical characteristics and package dimensions.
