SN74ABT16601DGGR

Universal Bus Functions Overview

The SN74ABT16601DGGR 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 three-state outputs with high drive capabilities, providing a high-level output current of -32 mA and a low-level output current of 64 mA. It exhibits a propagation delay of 4.5 ns and functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in a 56-pin TSSOP package.

Universal Bus Functions Feature Summary

• Supports bidirectional data transmission via 18 channels for universal bus applications
• Provides strong output drive capability suitable for demanding bus loads
• Features three-state outputs to facilitate multiple driver configurations on shared lines

Universal Bus Functions Applications

• High-speed parallel data bus interfaces
• Memory-to-memory or memory-to-I/O data transfers
• General-purpose wide-bus communication systems

Universal Bus Functions Procurement Notes

Verify the specific suffix DGGR corresponds to the TSSOP-56 reel packaging configuration. Confirm that the ABT logic family aligns with the required 5V operation and speed specifications for the target design. Ensure compatibility with existing board layouts utilizing the 56-pin thin-shrink small-outline package dimensions.

Universal Bus Functions Selection Notes

Select this component when an 18-bit width is required alongside the specific drive strength and speed characteristics of the ABT series. Compare against ALVCH or LVTH variants if lower voltage operation or different drive currents are needed. Verify that the 56-pin TSSOP footprint matches the available PCB space and thermal requirements.

Universal Bus Functions Part Context

This part belongs to the Texas Instruments 74ABT series of high-performance BiCMOS logic devices. It serves as a wide-bus interface solution, distinct from narrower 8-bit or 16-bit counterparts like the SN74ABT16245. The device integrates universal bus functionality into a single circuit block for efficient system integration.

Universal Bus Functions Replacement Considerations

SN74ABT16601DLG4 offers identical electrical performance in a TFSOP-56 package. SN74ABT16601DLRG4 provides the same function in a larger TVSOP-56 package. Cross-package replacements require verification of mechanical fit.
