SN74ABT16600DLR

Universal Bus Functions Overview

The SN74ABT16600DLR is an 18-bit universal bus transceiver utilizing BiCMOS technology. It integrates D-type latches and flip-flops for transparent, latched, clocked, or clock-enabled operation. The device features 3-state outputs controlled by OE, LE, CLK, and CLKEN inputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 150 MHz. Propagation delays range from 1.5 ns to 5.6 ns depending on the control path. The component is housed in a 56-pin SSOP package and functions over an operating temperature range of -40°C to +85°C.

Universal Bus Functions Feature Summary

• Combines D-type latches and flip-flops to support transparent, latched, clocked, and clock-enabled data flow modes.
• Features independent direction control with dedicated output-enable, latch-enable, clock, and clock-enable inputs for each bus direction.
• Utilizes EPIC-IIB BiCMOS design to significantly reduce power dissipation while maintaining high-speed performance.

Universal Bus Functions Applications

• High-density memory interface architectures
• Microprocessor-based system data buses
• Controlled data buffering and routing applications

Universal Bus Functions Procurement Notes

Verify current production status as the SN74ABT16600DLR is listed as obsolete in official documentation. Confirm availability through authorized distributors or secondary markets. Ensure the specific DL package variant matches the required PCB footprint. Validate RoHS compliance details against the latest manufacturer addendum before finalizing procurement orders.

Universal Bus Functions Selection Notes

Select this component when designing systems requiring 18-bit bidirectional data transfer with flexible storage modes. The ABT logic family provides TTL-compatible input levels suitable for mixed-voltage environments. Consider the 56-pin SSOP package constraints regarding thermal management and board space. Verify that the 150 MHz maximum frequency meets the system timing requirements.

Universal Bus Functions Part Context

This device belongs to Texas Instruments' Widebus family of universal bus transceivers. It shares architectural similarities with other 18-bit variants like the SN74ABT16601 but includes integrated storage elements. The SN74ABT16600 series is designed for high-performance digital systems requiring robust data handling capabilities across wide data paths.

Universal Bus Functions Replacement Considerations

Check for SN74ABT16601DGGR as a functional alternative if pin compatibility allows. Verify package dimensions and electrical characteristics against the original design specifications. Consult the manufacturer's obsolescence notices for recommended upgrades or lifecycle management strategies.
