MAX1609EEE+T 数据手册

Octal SMBus-to-Parallel I/O Expanders

use the send-byte protocol. The shorter receive-byte

protocol can be used instead of the read-byte protocol,

provided the correct data register was previously

selected by a read-byte or write-byte instruction. Use

caution with the shorter protocols in multimaster sys-

tems, since a second master could overwrite the com-

mand byte without informing the first master. The

receive-byte transmission that occurs immediately after

initial power-up returns the setting of NDR1. SPOR

does not reset the register pointer.

When using an external pull-up, high impedance corre-

sponds to an output high. To use the IO_ pins as TTL

inputs only, set the corresponding bit high. The

MAX1608 powers up with all IO_ pins set low; the

MAX1609 powers up with all IO_ pins set to high

impedance (Table 3).

edge triggered interrupts, while Register 3 are used to

mask falling-edge triggered interrupts. On power-up, all

interrupts are masked (Tables 4 and 5).

The IO_ Status Data Register (RSB, Table 6) reads the

actual TTL-logic level of the IO_ pins. The IO_ pins are

sampled on the falling edge of the third byte’s acknowl-

edge (ACK) for a read-byte format, or on the falling

edge of the first byte’s ACK for a receive-byte protocol

(Figure 5). There is a 15µs data-setup time require-

ment, due to the slow level translators needed for high-

voltage (28V) operation. Data-hold time is 300ns. Do

not write to the RSB register because writes to read-

only registers are redirected to NDR1. SMBus sends

Data Registers

The MAX1608/MAX1609 each have seven data regis-

ters, three normal registers, three suspend registers,

and one readback register. The SMBUS line deter-

mines which registers controls the output states and

the interrupt mask states (normal registers if SUSBUS =

1, suspend registers if SMBSUS = 0).

Registers 1 (NDR1 and SDR1) set the state of each of

the eight outputs to either low or high impedance.
