74ALVCH32501ZKFR

Overview

The SN74ALVCH32501ZKFR is a universal bus transceiver manufactured by Texas Instruments, belonging to the ALVCH logic series. It features 32 channels organized into two circuits and utilizes a BGA-Microstar-114 package for surface mount installation. The device operates within a supply voltage range of 1.65 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. Key electrical parameters include a propagation delay of 5.6 ns, with high-level and low-level output currents rated at -24 mA and 24 mA respectively. The outputs are configured as 3-State.

Feature Summary

• Provides universal bus functionality through bidirectional data transmission capabilities across multiple channels.
• Features 3-state outputs to facilitate efficient bus line management and signal isolation.
• Designed for CMOS logic applications requiring wide voltage operation compatibility.

Applications

• High-density memory module interfacing
• Bus-oriented architecture systems
• General-purpose bidirectional data transfer

Procurement Notes

This component is officially listed as obsolete or not recommended for new designs by the manufacturer. Availability is restricted, and sourcing may require checking secondary distributors or surplus markets. Verify current lifecycle status and lead times carefully before integration into production plans.

Selection Notes

Select this part when a 32-channel universal bus transceiver with ALVCH performance characteristics is required. Ensure the design accommodates the BGA-Microstar-114 footprint and meets the 1.65 V to 3.6 V power supply constraints. Consider the 5.6 ns propagation delay for timing analysis in high-speed bus applications.

Part Context

The SN74ALVCH32501 is part of Texas Instruments' extensive ALVCH family, which offers advanced low-voltage CMOS technology. This specific model serves as a high-channel-count solution for complex bus architectures, distinguishing itself from lower-density variants like the 74ALVCH32444 through its 32-channel capacity and specialized packaging.

Replacement Considerations

Direct substitutes should be sought within the SN74ALVCH32501 family. Verify pinout compatibility and electrical specifications against alternative vendors offering equivalent 32-channel bus transceivers in compatible packages.
