SN74ABT162601DLR

Universal Bus Functions Overview

The SN74ABT162601DLR is an 18-bit universal bus transceiver manufactured by Texas Instruments. It utilizes ABT BiCMOS logic technology and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 4.8 ns and supports output currents up to 32 mA (high) and 64 mA (low). It is housed in a 56-pin SSOP package and functions as a single circuit with independent control capabilities.

Universal Bus Functions Feature Summary

• Supports bidirectional data transfer across 18 channels
• Provides independent output enable for each direction
• Integrates clock enable functionality for controlled data latching

Universal Bus Functions Applications

• High-speed parallel data bus interfaces
• Memory-to-memory data transfers
• General-purpose 18-bit bus bridging applications

Universal Bus Functions Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 56-SSOP footprint matches the target PCB design constraints. Ensure the 4.5V to 5.5V operating voltage aligns with the system power rails before finalizing component selection.

Universal Bus Functions Selection Notes

Select this component when an 18-bit wide interface is required with high drive strength capabilities. The ABT series offers faster switching speeds compared to standard CMOS alternatives. Verify that the 56-pin SSOP package dimensions fit within the available board space and thermal management requirements of the enclosure.

Universal Bus Functions Part Context

This part belongs to the Texas Instruments SN74ABT family, which combines the speed of bipolar transistors with the low power consumption of CMOS technology. The 162601 designation specifically identifies it as an 18-bit universal bus transceiver within the broader logic IC portfolio designed for high-performance digital systems.

Universal Bus Functions Replacement Considerations

The SN74ABT162601DLRG4 is a documented alternate ordering suffix for the same functional device. Cross-reference pinouts and electrical characteristics carefully when substituting with other 18-bit bus transceivers from different manufacturers.
