SN74ALVCH16835DL

Overview

The SN74ALVCH16835DL 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 features three-state outputs. The device utilizes a 56-pin SSOP package and supports surface-mount installation. It functions as a single circuit with 18 channels, providing high-level output current of -24 mA and low-level output current of 24 mA. The propagation delay is specified at 5.2 ns. The component is designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports 18-bit bidirectional data transfer across a universal bus architecture
• Features independent control mechanisms for direction and output enablement
• Provides three-state outputs to facilitate system bus isolation

Applications

• High-density memory mapping systems requiring wide data buses
• Microprocessor-based systems utilizing 18-bit data interfaces
• Complex digital logic circuits necessitating universal bus transceivers

Procurement Notes

Verify the specific suffix 'DL' corresponds to the 56-SSOP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 1.65 V to 3.6 V operating voltage range. Validate thermal performance requirements against the -40°C to +85°C industrial temperature specification during the procurement phase.

Selection Notes

Select this component for applications requiring an 18-bit width interface rather than standard 8 or 16-bit configurations. The ALVCH series offers optimized performance for lower voltage operations compared to legacy families. Consider the 56-pin SSOP footprint constraints during PCB layout planning. Evaluate the 5.2 ns propagation delay against system timing requirements to ensure signal integrity.

Part Context

This part belongs to the Texas Instruments SN74ALVCH family of advanced CMOS logic devices. These components are engineered for high-speed digital applications requiring low power consumption. The universal bus transceiver category provides flexible data routing capabilities. The SN74ALVCH16835 specifically addresses designs needing wide parallel data transmission with robust electrical characteristics.

Replacement Considerations

Consult official substitution guides for equivalent 18-bit universal bus transceivers within the same logic family. Verify pinout compatibility and electrical specifications before replacing existing inventory. Cross-reference datasheets to confirm identical package dimensions and thermal properties.
