Key features
AS2591 is a CMOS mixed-mode integrated
circuit for driving LCD-displays with 4
backplanes and 12 or 16 segments. It is
controled via a simple 2 wire bus and a chip
select signal. The device also includes a
“talk timer” which starts 5 seconds after the
last digit entry. The timer also shows the
elapsed time up to 5 seconds after the
ON-HOOK transition.

PROGRAM
FOR SCHEMATIC DIAGRAM (page 21)
Notes:
 1. DC voltage measurements are taken with electronic
     voltmeter from negative terminal.
     (Add 40 mA to telephone line from the loop simulator.)
 2. This schematic diagram may be modified at any time
     with the development of new technology.
The key arrangement for programs
in P14 is as shown in the drawing.
