G570
Global Mixed-mode Technology Inc.
Logic Input and Outputs
The serial interface consists of DATA, CLOCK, and
LATCH leads. The data is clocked in on the positive
leading edge of the clock (see Figure 2). The 9-bit (D0
through D8) serial data word is loaded during the positive
edge of the latch signal. The latch signal should occur
before the next positive leading edge of the block.
The shutdown bit of the data word places all V
CC
and V
PP
outputs in a high-impedance state and reduces chip qui-
escent current to 2μA to conserve battery power.
The G570 serial interface is designed to be compatible
with serial-interface PCMCIA controllers and current
PCMCIA and Japan Electronic Industry Development
Association (JEIDA) standards.
An overcurrent output (OC ) is provided to indicate an
overcurrent condition in any of the V
CC
or V
PP
outputs as
previously discussed.
NOTE:
MOSFET switches S9 and S12 have a back-gate diode from the source to the drain.
Unused switch inputs should never be grounded.
