ICM7211AM
FN3158.7
4-Digit, LCD Display Driver
The ICM7211AM device is a non-multiplexed four-digit
seven-segment CMOS LCD display decoder-driver.
This device is configured to drive conventional LCD displays
by providing a complete RC oscillator, divider chain,
backplane driver, and 28 segment outputs.
It also has a microprocessor compatible input configuration,
which provides data input latches and Digit Address latches
under control of high-speed Chip Select inputs. These devices
simplify the task of implementing a cost-effective
alphanumeric seven-segment display for microprocessor
systems, without requiring extensive ROM or CPU time for
decoding and display updating.
The ICM7211AM provides the “Code B” output code, i.e.,
0-9, dash, E, H, L, P, blank, but will correctly decode true
BCD to seven-segment decimal outputs.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
*Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
