SN74ABT162601DGGR

Universal Bus Functions Overview

The SN74ABT162601DGGR is an 18-bit universal bus transceiver from the Texas Instruments 74ABT series. It utilizes BiCMOS technology and operates within a supply voltage range of 4.5V to 5.5V. The device features a propagation delay of 4.8ns and provides high-level output current of -32mA and low-level output current of 64mA. It is housed in a 56-TFSOP package with a width of 6.10mm and supports an operating temperature range from -40°C to +85°C.

Universal Bus Functions Feature Summary

• Supports 18-bit bidirectional data transmission via a single universal bus architecture
• Utilizes BiCMOS technology for high-speed performance with reduced power consumption
• Provides robust drive capability with asymmetric output currents for signal integrity

Universal Bus Functions Applications

• High-speed parallel data buses in computing systems
• Memory interface circuits requiring wide data paths
• Industrial control systems with multiple I/O expansion requirements

Universal Bus Functions Procurement Notes

Verify the specific suffix DGGR corresponds to the 56-TFSOP package and tape-and-reel orientation. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to PCB assembly planning. Ensure the ordering part number matches the exact logic family and pinout configuration required by the design schematic.

Universal Bus Functions Selection Notes

Select this component when an 18-bit wide data path is necessary at 5V logic levels. The ABT series offers a balance between speed and power, suitable for applications where standard 74F or 74LS families are too slow but CMOS families lack sufficient drive strength. Verify that the system voltage remains strictly within the 4.5V to 5.5V window to ensure correct logic thresholds.

Universal Bus Functions Part Context

This device belongs to the Texas Instruments 74ABT family of advanced BiCMOS logic devices. It serves as a universal bus transceiver, distinct from dedicated latches or drivers. The 162601 variant specifically handles 18 bits of data, making it wider than standard 8-bit or 16-bit counterparts like the 74ABT16245.

Universal Bus Functions Replacement Considerations

SN74ABT162601DLR shares identical electrical specifications and functionality but utilizes a 56-SSOP package instead of TFSOP. Cross-reference pinouts carefully if mechanical clearance differs. Other 18-bit ABT transceivers may require verification of voltage compatibility and drive current limits.
