Overview
The V62/03607-02YE is an octal buffer and line driver from the SN74HC244-EP enhanced product family. It features two independent 4-bit buffers with separate output-enable inputs, providing non-inverted data transfer. The device utilizes a TSSOP (PW) package and supports a supply voltage range of 2V to 6V. It operates within an extended temperature range of -55°C to 125°C and includes three-state outputs for driving bus lines or memory address registers.
Feature Summary
- Enhanced Diminishing Manufacturing Sources (DMS) support
- Extended temperature performance up to -55°C to 125°C
- Three-state outputs drive bus lines or buffer memory address registers
- High-current outputs capable of driving up to 15 LSTTL loads
Applications
- Memory address drivers
- Clock drivers
- Bus-oriented receivers and transmitters
Procurement Notes
Verify the specific suffix '02YE' corresponds to the TSSOP (PW) package variant in official documentation. Confirm that the -55°C to 125°C operating temperature range aligns with your system requirements. Ensure compliance with RoHS standards and check for any export restrictions associated with this military-grade component before finalizing procurement.
Selection Notes
Select this component when high-density octal buffering is required alongside extended industrial or military temperature capabilities. The HC244-EP series offers improved reliability through controlled baseline manufacturing and enhanced change notification processes compared to standard catalog parts. Consider the TSSOP package constraints if board space is limited.
Part Context
This part belongs to the Texas Instruments SN74HC244-EP enhanced product line, designed for high-reliability applications. It is distinct from the standard SN74HC244 catalog version and the automotive SN74HC244-Q1. The EP designation indicates qualification pedigree including HAST and electromigration testing.
Replacement Considerations
Direct replacements include other SN74HC244-EP variants such as V62/03607-01XE (SOIC package). Standard catalog equivalents like SN74HC244 may be used if extended temperature ranges and DMS support are not critical.
