or exceeds +150°C. In this state, the V
disabled (output goes high impedance) until the junc-
tion temperature falls below +150°C.
The slave address byte consists of a 7-bit slave
address plus a R/W bit (see Figure 5). The DS3514’s
slave address is determined by the state of the A0 pin.
This pin allows up to two devices to reside on the same
I
corresponding bit position in the slave address.
Conversely, connecting A0 to V
corresponding bit position. For example, the DS3514’s
slave address byte is C0h when A0 is grounded. I
communication is described in detail in the I
Interface Description section.
The list of registers/memory contained in the DS3514 is
shown in the Memory Map section. Also shown for
each of the registers is the memory type, accessibility,
