Absolute Maximum Ratings are
stress ratings. Stresses in excess of
these ratings can cause permanent
damage to the device. Functional
operation of the device at these or
any other conditions beyond those
indicated in the operational sections
of this data sheet is not implied.
Exposure of the device to the
absolute maximum ratings for an
extended period may degrade the
device and affect its reliability.
ESD Warning
ESD (electrostatic discharge) sensitive device. Although the MX877 features proprietary ESD protection circuitry,
permanent damage may be sustained if subjected to high energy electrostatic discharges. Proper ESD precautions
are recommended to avoid performance degradation or loss of functionality.

Notes: To avoid unwanted output during VPWR application and system initialization, keep OE at a logic

Thermal Resistance is measured in still air with the device soldered to a 6 square inch board
without a ground plane. Applications may require derating of the specified maximum currents to
avoid exceeding the maximum operation junction temperature.

MX877
Functional Description
The MX877 is an 8 channel high voltage driver
with 8-bit input control. The MX877 interfaces to a
microprocessor through a standard 3 wire serial
interface and an active low chip select, or can be
used in a parallel-in, parallel-out configuration.
Serial Data Transfer Example
Parallel data is transferred to the I/O register of
the MX877 through the parallel input pins, IN0
through IN7 on the falling edge of the chip select
pin, CSÄ. When CSÄ is in a logic low state, serial
data can be transferred to the I/O register through
the serial input pin, SDI, and from the I/O register
through the serial output pin, SDO. Parallel or
serial input data is transferred from the I/O
register to the latch and high voltage output
drivers, OUT0 through OUT7, on the positive
edge of CSÄ. This data remains latched until the
next positive edge of CSÄ.

CS*
SCK
SDO
The 8-bit I/O shift register is clocked by the
serial clock pin, SCK. Serial data presented at the
SDI pin is transferred to the shift register on the
positive edge of SCK. Data shifts out of the
register through the SDO pin on the negative
edge of SCK. SDI and SCK are ignored, and
SDO transitions to a high impedance condition
when CSÄ is at a logic high state.
Serial data is received by the MX877 through
the SDI pin. This data is accepted on the rising
edge of SCK. A specific output is programmed to
a logic high state if SDI is at a logic high state
during the rising edge of SCK. Conversely, a
specific output is programmed to a logic low state
if SDI is at a logic low state during the rising edge
of SCK. Outputs transition to their programmed
states on the positive edge of CSÄ if the output
enable pin, OE is in a logic high state.

Devices may be serially cascaded by
connecting SDO to SDI of the next device. Pins
SCK and CSÄ are common to all devices in serial
cascade. For n-cascaded devices the CSÄ should
remain low for 8n cycles of SCK.
An output enable pin, OE enables the driver
outputs OUT0 through OUT7 when logic high. A
logic low level on OE forces the OUT0 through
OUT7 outputs to a high impedance state.
The MSB input data (IN7) is presented at the
serial output pin, SDO on the falling edge of CSÄ.
Input data from IN6 through IN0 is sequentially
presented at SDO on negative SCK transitions if
CSÄ remains in a logic low state. If CSÄ is at a
logic low state beyond 8 cycles of SCK, SDI data
that has propagated through the I/O register will
then be presented at SDO. The SDO pin
transitions to a high impedance state when CSÄ
is in a logic level high state, thus allowing multiple
serial peripherals to share the microprocessor
data pin.

IN7
The MX877 can also operate as a parallel-in,
parallel-out level shifter and driver. SCK must
remain at a logic low state when operating in this
mode. Parallel input data presented to IN0
through IN7 is captured on the falling edge of
CSÄ. This data is transferred to OUT0 through
OUT7 on the rising edge of CSÄ, and remains
latched until the next rising edge of CSÄ.
