Operating temperature range
Standard product, (A) grade product: −40 to +85°C
(A2) grade product: −40 to +125°C
Package
• 30-pin plastic SSOP
• 32-pin plastic SDIP
Note Use these products in the following voltage range because the detection voltage (VPOC) of the power-on-
clear (POC) circuit is the supply voltage range.
Standard product, (A) grade product: 2.2 to 5.5 V, (A2) grade product: 2.26 to 5.5 V
