Overview
The V62/04763-01XE is a 16-bit bus transceiver with 3-state outputs, part of the SN74ALVCH16245-EP family. It operates from 1.65 V to 3.6 V and features a maximum propagation delay of 3 ns at 3.3 V. The device provides ±24-mA output drive current at 3.3 V and includes bus hold on data inputs to eliminate external pullup/pulldown resistors. Latch-up performance exceeds 250 mA per JESD 17, and ESD protection exceeds 2000-V human-body model and 200-V machine model standards.
Feature Summary
- Controlled baseline with one assembly/test site and one fabrication site
- Enhanced diminishing manufacturing sources support
- Bus hold on data inputs eliminates need for external pullup/pulldown resistors
- ESD protection exceeding JESD 22 standards
Applications
- Asynchronous communication between data buses
- Data transmission from A bus to B bus or vice versa
- Isolation of buses via output-enable input
Procurement Notes
Verify the specific ordering suffix matches the required temperature range and package configuration. Confirm that the controlled baseline and enhanced DMS support align with project reliability requirements. Ensure compatibility with existing system voltage levels and interface standards before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring 16-bit asynchronous data transfer with low power consumption. Consider the extended temperature range options available within the family. Evaluate the need for bus hold functionality to simplify circuit design by removing external resistors. Verify pinout compatibility with target PCB layout constraints.
Part Context
This part belongs to the Texas Instruments Widebus family of 16-bit bus transceivers. It is an enhanced product (EP) version designed for high reliability. The device is functionally equivalent to the SN74ALVCH16245 but meets specific military or aerospace qualification criteria through its controlled baseline and enhanced manufacturing support.
Replacement Considerations
Direct substitutes include other SN74ALVCH16245 variants with compatible temperature ranges and packages. Verify pin-to-pin compatibility and electrical specifications before substitution. Catalog versions may lack the enhanced manufacturing support features.
