Electrical Characteristics:

Unless otherwise noted, VCC is over the full voltage range, TA = -40°C to 105°C.

Typical values at TA = 25°C, VCC = 5V for L/M/J devices, VCC = 3.3V for T/S devices and VCC = 3V for R devices.

Notes:

1. Production testing done at TA = 25°C. Over-temperature specifications guaranteed by design only, using six sigma design limits.

2. RESET output is active LOW for the ASM809 and RESET output is active HIGH for the ASM810.
