NOTIFICATION OF PACKAGE NOMENCLATURE ALIAS
(for Standard Linear and Logic device names of greater than 18 characters)
TI is converting from its current order-entry system to a more advanced system. This conversion requires
modifications, both internal and external, to TIs current business processes. This new system will ultimately provide
significant improvements to all facets of TIs business from production, to order entry, to logistics. One change
required is a limitation of TI part numbers to no more than 18 characters in length. Based on customer inputs, Standard
Linear and Logic determined the least disruptive implementations as outlined below:
1. Package alias
TI will use a package alias to denote specific package types for devices currently exceeding 18 characters in
length. Table 1 shows a mapping of package codes to an alias single-character representation.

Current: SN74 ALVCH 162269A DGGR
New: SN74 ALVCH 162269A GR1
2. Resistor-option nomenclature
For devices greater than 18 characters with input and output resistors, TI will adopt a simplified
nomenclature to designate the resistor option. This will eliminate the redundant 2 (designating output
resistors) when the part number also contains an R (designating input/output resistors).

There is no change to the device or data-sheet electrical parameters. The packages involved and the changes in
nomenclature are noted in Table 1.
These nomenclature changes are being gradually implemented. The first customer-visible conversions for TI logic
devices will be made to data sheets. Over the next few months, TI logic data sheets will be updated. These changes
in device nomenclature do not reflect a change in device performance or process characteristics.
