SN74ALVCH162841GR

Overview

The SN74ALVCH162841GR is a 20-bit bus-interface D-type latch with 3-state outputs manufactured by Texas Instruments. It operates within a voltage range of 2.3 V to 3.6 V and features a propagation delay of 5.6 ns. The device utilizes CMOS logic technology and provides high-level and low-level output currents of 12 mA each. It is housed in a 56-TSSOP package, supports surface-mount installation, and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides 20-bit data storage capability via D-type transparent latch architecture
• Features 3-state outputs for effective bus line management and isolation
• Utilizes EPIC submicron CMOS process for enhanced performance and low power consumption

Applications

• High-density data buffering in digital systems
• Bus interface circuits requiring 20-bit width
• Memory address latching applications

Procurement Notes

Verify the specific suffix GR corresponds to the 56-TSSOP tape and reel packaging configuration. Confirm that the ALVCH series designation aligns with the required 3.3V operation standards for your target circuit design. Ensure compatibility with the specified -40°C to +85°C industrial temperature range before finalizing procurement orders.

Selection Notes

Select this component when a 20-bit wide latch with tri-state control is required. The ALVCH series offers improved switching speeds compared to standard ALVC devices while maintaining 3.3V compatibility. Consider the 56-TSSOP package constraints for PCB layout and thermal management requirements during the selection phase.

Part Context

This part belongs to the Texas Instruments 74ALVCH family, which combines advanced CMOS technology with 3.3V operation. The ALVCH series is designed for high-speed applications requiring low power dissipation. It serves as a critical component in complex digital logic designs where reliable data retention and bus isolation are essential for system stability.

Replacement Considerations

Check for direct pin-compatible substitutes within the same ALVCH family. Verify that alternative parts maintain the 20-bit width and 3-state output specifications. Ensure any replacement matches the 56-TSSOP package dimensions and electrical characteristics defined in the official datasheet.
