General Description
The MX7545A and MAX7645, 12-bit CMOS multiplying
digital-to-analog converters (DAG) with internal data
latches, are improved versions of the industry stand-
ard MX7545. The MX7545A features a 100ns max write
pulse width (150ns for MAX7645) which allows inter-
facing to a wide range of fast 8- and 16-bit
microprocessors.
The MX7545A/MM7645_ige loaded by a single_12-bit
w_ide word when CS and WR are both low. The CS and
WR inputs can be connected low making the input
data latches transparent and allowing unbuffered
operation of these DACs.
The MX7545A is specified both with a single +5V and
+15V power supply. With a +5V supply, the digital
inputs are TTL and +5V-CMOS compatible while high
voltage CMOS compatibility is maintained with a +15V
