Package

PC = PCDIP28

MH(3) = SOH28

Temperature Range

1 = 0 to 70°C

Shipping Method

For SOH28:

blank = Tubes (Not for New Design - Use E)

E = Lead-free Package (ECO PACK®), Tubes

F = Lead-free Package (ECO PACK®), Tape & Reel

TR = Tape & Reel (Not for New Design - Use F)

For PCDIP28:

blank = Tubes

Note: 1. The M48T59 part is offered with the PCDIP28 (e.g., CAPHAT™) package only.

2. Contact local ST sales office for availability of 3.3V version.
