Description
The ICM7211 (LCD) and ICM7212 (LED) devices constitute
a family of non-multiplexed four-digit seven-segment CMOS
display decoder-drivers.
The ICM7211 devices are configured to drive conventional
LCD displays by providing a complete RC oscillator, divider
chain, backplane driver, and 28 segment outputs.
The ICM7212 devices are configured to drive common-
anode LED displays, providing 28 current-controlled, low
leakage, open-drain N-Channel outputs. These devices
provide a brightness input, which may be used at normal
logic levels as a display enable, or with a potentiometer as a
continuous display brightness control.
These devices are available with multiplexed or microproces-
sor input configurations. The multiplexed versions provide four
data inputs and four Digit Select inputs. This configuration is
suitable for interfacing with multiplexed BCD or binary output
devices, such as the ICM7217, ICM7226, and ICL7135. The
microprocessor versions provide 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 micro-
processor systems, without requiring extensive ROM or CPU
time for decoding and display updating.
The standard devices will provide two different decoder
configurations. The basic device will decode the four bit
binary inputs into a seven-segment alphanumeric hexadeci-
mal output. The “A” versions will provide the “Code B” output
code, i.e., 0-9, dash, E, H, L, P, blank. Either device will cor-
rectly decode true BCD to seven-segment decimal outputs.
