PART NUMBERING

Table 12. Ordering Information Scheme

Note: 1. The M48T58 part is offered with the PCDIP28 (e.g., CAPHAT™) package only.

2. The SOIC package (SOH28) requires the battery package (SNAPHAT®) which is ordered separately under the part number

“M4TXX-BR12SH” in plastic tube or “M4TXX-BR12SHTR” in Tape & Reel form.

Caution: Do not place the SNAPHAT battery package “M4TXX-BR00SH” in conductive foam as it will drain the lithium button-cell

battery.

For a list of available options (e.g., Speed, Package) or for further information on any aspect of this device,
