SN74ALVCHR16601GR

Overview

The SN74ALVCHR16601GR is an 18-bit universal bus transceiver from the Texas Instruments ALVCHR logic series. It utilizes CMOS technology and operates within a supply voltage range of 1.65 V to 3.6 V. The device features 3-state outputs and is housed in a 56-pin TSSOP package. Key electrical parameters include a maximum propagation delay of 6.3 ns, a maximum supply current of 40 µA, and output drive capabilities of -12 mA (high) and 12 mA (low). It supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Supports bidirectional data transfer via universal bus architecture
• Provides independent control for each direction with clock enable functionality
• Features 3-state outputs for efficient bus line management

Applications

• High-speed data acquisition systems
• Memory buffer applications
• General-purpose 18-bit bus interfaces

Procurement Notes

Verify the specific ordering suffix 'GR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the ALVCHR logic family specifications align with the target system's voltage levels and signal integrity requirements before finalizing procurement orders.

Selection Notes

Select this component when an 18-bit wide interface is necessary within low-voltage environments operating between 1.65 V and 3.6 V. The ALVCHR series offers optimized performance for high-speed applications requiring moderate drive strength. Ensure the design accommodates the 56-pin TSSOP footprint and thermal characteristics associated with this package type.

Part Context

This device belongs to the SN74ALVCHR16601 product family, which represents Texas Instruments' advanced low-voltage CMOS logic solutions. The family is designed to provide high-speed operation while maintaining low power consumption, making it suitable for portable and battery-operated electronic equipment requiring reliable data transmission.

Replacement Considerations

The SN74ABT16601DGGR serves as a compatible alternative within the same package format. Note that the ABT series operates at a higher voltage range (4.5 V to 5.5 V) compared to the ALVCHR series, requiring careful evaluation of system voltage compatibility.
