Overview
The SN74ALVCH16835DGG is an 18-bit universal bus transceiver from the Texas Instruments ALVCH logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes a TSSOP-56 package. The device features three-state outputs with drive capabilities of 24 mA at both high and low states. It supports bidirectional data transmission with independent direction control for each A-to-B or B-to-A path. The component functions across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Supports bidirectional data transfer between two buses with independent direction control
- Provides level translation capabilities between different voltage domains
- Features three-state outputs to isolate the bus when disabled
Applications
- Mobile applications requiring low-voltage operation
- Consumer products utilizing portable battery power
- Handheld terminals and communication devices
- PDA systems and personal digital assistants
Procurement Notes
Verify the specific suffix 'DGG' corresponds to the TSSOP-56 package variant in official documentation. Confirm RoHS compliance status through current manufacturer datasheets, as environmental declarations may change. Ensure design compatibility with the specified 1.65 V to 3.6 V operating range before integration into final assemblies.
Selection Notes
Select this component for designs requiring 18-bit wide data paths with flexible direction control. It is suitable for systems needing interface between varying voltage levels within the ALVCH specification. Consider the TSSOP-56 footprint constraints and thermal requirements during PCB layout planning.
Part Context
This part belongs to the SN74ALVCH16835 series of universal bus transceivers. It is designed for high-density memory and interface driving in mobile and consumer electronics. The ALVCH family offers improved performance over standard LVCH devices while maintaining compatibility with existing system architectures.
Replacement Considerations
Direct substitutes include other SN74ALVCH16835 variants with compatible packaging. Verify pinout and electrical specifications match exactly when considering alternative packages or updated revisions from the manufacturer.
