SN74ALVCH16601DGGR

Overview

The SN74ALVCH16601DGGR is an 18-bit universal bus transceiver manufactured by Texas Instruments. It utilizes BiCMOS technology and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 4.5 ns and supports output currents of up to 32 mA for high-level and 64 mA for low-level states. It is housed in a 56-pin TSSOP package and functions as a single circuit with three-state outputs across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports 18-bit bidirectional data transmission via universal bus architecture
• Provides three-state outputs for effective bus line isolation
• Utilizes BiCMOS technology for enhanced switching performance

Applications

• High-speed parallel data bus interfaces
• Memory-to-memory data transfers
• System control signal routing

Procurement Notes

Verify the specific suffix 'DGGR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 56-TSSOP footprint matches the target PCB layout dimensions. Ensure the 4.5 V to 5.5 V supply voltage requirement aligns with the system power rails before finalizing procurement orders.

Selection Notes

Select this component when an 18-bit wide interface is necessary for high-speed data transfer applications. The BiCMOS technology offers superior drive strength compared to standard CMOS alternatives. Consider the 56-pin TSSOP package constraints during board design to ensure adequate thermal dissipation and trace routing space for the extensive I/O connections.

Part Context

This part belongs to the SN74ALVCH series, which focuses on low-voltage logic solutions. While similar to other 18-bit transceivers, the ABT variant specifically leverages BiCMOS technology for faster switching speeds. It serves as a bridge between different system components requiring robust, high-capacity data pathways.

Replacement Considerations

The SN74ABT16601DGGR is a confirmed substitute offering identical functionality and pinout compatibility. Verify that the replacement maintains the same BiCMOS characteristics and electrical specifications to ensure seamless integration without redesigning the host circuit.
