SN74ALVCH162601DLR

Overview

The SN74ALVCH162601DLR is an 18-bit universal bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes BiCMOS technology. The device features three-state outputs and is housed in a 56-pin TSSOP package with a width of 6.10 mm. It supports bidirectional data transfer and includes independent output enable controls for each direction. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports 18-bit bidirectional data transmission via universal bus architecture
• Provides independent control for output enable signals on each direction
• Features three-state outputs compatible with various system loads

Applications

• High-density memory interface implementations
• Microprocessor-based system data routing
• Control signal distribution networks

Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 56-TSSOP footprint matches the target PCB design constraints. Ensure the 1.65 V to 3.6 V supply voltage range aligns with the system power rails before finalizing procurement orders.

Selection Notes

Select this component when an 18-bit wide data path is required within low-voltage logic families. The ALVCH series offers lower power consumption compared to standard LVCMOS options while maintaining high-speed performance. Consider the 56-pin package density if board space is limited, ensuring adequate thermal management for the specified operating temperature range.

Part Context

This device belongs to the Texas Instruments 74ALVCH logic family, designed for advanced low-voltage CMOS applications. The 162601 variant specifically addresses the need for wide-bus connectivity in portable and battery-operated systems. It serves as a bridge between different logic domains requiring robust signal integrity and minimal power draw during active and standby states.

Replacement Considerations

Cross-reference with SN74ALVCH162601GR for identical electrical specifications but in a TFSOP package. Verify pinout compatibility and physical dimensions before substituting to ensure mechanical fit within the existing enclosure or chassis design.
