Reference Voltage Input
14
Clock input pin.
12
Serial data input pin that is used to read 24-bit words into the E6435 input shift
register.
15
Digital input pin that triggers the transfer of data from the serial data input shift
register to the central DAC register at up to 33 MHz.
10
Digital input pin that is used to update the rank A latches.
9
Digital input pin that is used to update the rank B latches.
66
Digital input pin that selects either data in the rank A or rank B latches as the DAC
input.
11
Digital input pin used to select between "4-channel" or "8-channel" decoding
schemes.
7
Digital input pin that is used to initialize the E6435 by placing it into a known state.
6
Digital input pin that is used to set all DAC outputs ~0V (Voltage output DACs) or
~0mA (Current output DACs).
17
Serial data output pin.
16
Digital input pin that is used to enable/disable the DAC_OUT and LD_OUT functions.
54
High impedance analog voltage output pin that displays the output level of a selected
DAC (used for system level diagnostics) when enabled using the TEST_MODE pin.
8
Digital input pin that is used to begin the transmission of serial data through the
LD_OUT pin.
13
Serial data output pin used to display the binary value stored in a selected rank A or
rank B latch.
