SA5777A Pin Descriptions for the D Package (Small Outline)
Name
C1–
Negative output connection to the TAN coil of meter #1.
C1+
Positive output connection to the TAN coil of meter #1.
NC

supply. Pins 6, 20 and 23 should be connected on the circuit board.
V
BB
Analog supply. Nominally 13.5 V.
DATA
OUT
Serial data output. Output of the internal shift register. When a new data word is shifted in, the old word is shifted out
the DATA
OUT
pin. DATA
OUT
output is always active.
DATA
IN
Serial data input. A new data word is serially shifted into the part on the rising edge of S
CLK
. The data is shifted in MSB
first, gauge 1 first.

V
CC
5 V logic supply. The internal latches and registers are set to zero on the rising edge of this signal.
OE
Output drivers are turned off when this input is low.
S
CLK
Serial clock input. Data is loaded into the part on the rising edge of S
CLK
. Data is shifted out of DATA
OUT
on the falling
edge of S
CLK
.
CS
Active high chip select input. When CS is high, the part is enabled to receive a new serial input word. The high-to-low
transition of CS loads the new 20-bit word into the DAC registers and updates the output.
NC
No connect
NC
No connect
ST
Status output. This is an open drain output and goes low when the coil output buffers (C1+, C1–, C2+, C2–, COM) have
been disabled. The coil outputs may be disabled due to shorted outputs, over-temperature conditions, power-on reset,
or by the output enable (OE) pin. Multiple status outputs , ST, may be wire OR’ed together.
D
GND
Ground for V
CC
supply. Connect to Pins 6 and 23.
