ML2258*
µP Compatible 8-Bit A/D Converter
with 8-Channel Multiplexer
GENERAL DESCRIPTION
The ML2258 combines an 8-bit A/D converter, 8-channel
analog multiplexer, and a microprocessor compatible 8-
bit parallel interface and control logic in a single
monolithic device.
Easy interface to microprocessors is provided by the
latched and decoded multiplexer address inputs and
latched three-state outputs.
The device is suitable for a wide range of applications
from process and machine control to consumer,
automotive, and telecommunication applications.
The ML2258 is an enhanced, pin-compatible, second
source for the industry standard ADC0808/ADC0809. The
ML2258 enhancements are faster conversion time, true
sample and hold function, superior power supply
rejection, wider reference range, and a double buffered
data bus as well as faster digital timing. All parameters
are guaranteed over temperature with a power supply
voltage of 5V ±10%.

FUNCTION
Analog input 3.
Analog input 4.
Analog input 5.
Analog input 6.
Analog input 7.
Start of conversion. Active high digital
input pulse initiates conversion.
End of conversion. This output goes
low after a START pulse occurs, stays
low for the entire A/D conversion, and
goes high after conversion is
completed. Data on DB0–DB7 is valid
on rising edge of EOC and stays valid
until next EOC rising edge.
Data output 3.
Output enable input. When OE = 0,
DB0–DB7 are in high impedance
state; OE = 1, DB0–DB7 are active
outputs.
Clock. Clock input provides timing for
A/D converter, S/H, and digital
interface.
Positive supply. 5V ± 10%.
Positive reference voltage.
