Pin Functions
DESCRIPTION
Serial data true input.
Serial data complement input.
Negative power supply (ground)
Bias resistor. Connect a 750-Ω resistor to V_CC.
Reset input. RSTI has an internal pullup, LVCMOS, 2-state logic.
H = Normal operation.
L = Device reset. The device operates with default register settings. Forcing RSTI low
also forces RSTO low.
Output driver enable, LVCMOS, 2-state logic. ENABLE has an internal pullup.
H = Normal operation.
L = Output driver powered off.
SMBus bidirectional data pin, LVCMOS, 2-state logic, open drain. When functioning as
an output, it is open drain. This pin requires an external pullup.
SMBus clock input, LVCMOS, 2-state logic, open drain. SCL is input only. This pin
requires an external pullup.
Positive power supply (3.3 V)
Output slew rate control, LVCMOS, 2-state logic. SD/HD has an internal pulldown.
H = Output rise or fall time complies with ST 259.
L = Output rise or fall time complies with ST 424 or 292.
Serial data complement output.
(1) G = Ground, I = Input, O = Output, and P = Power
