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 four-digit non-multiplexed direct LED displays with 28 current-limited segment outputs.
The Intersil ICM7211 and ICM7212 devices constitute a family of non-multiplexed four-digit seven-segment CMOS display decoder-drivers. The ICM7211 is configured to drive conventional LCD displays by providing a complete RC oscillator, divider chain, backplane driver, and 28 segment outputs. The ICM7212 is configured to drive common-anode LED displays, providing 28 current-controlled, low leakage, open-drain N-Channel outputs.
