ICM7211A - 4-Digit LCD Display Driver

Datasheet Summary

Description

The ICM7211A (LCD) device constitutes a family of non-multiplexed four-digit seven-segment CMOS display decoderdrivers.

The ICM7211A devices are configured to drive conventional LCD displays by providing a complete RC oscillator, divider chain, backplane driver, and 28 segment outputs.

Features

  • Four Digit Non-Multiplexed 7 Segment LCD Display Outputs with Backplane Driver.
  • Complete Onboard RC Oscillator to Generate Backplane Frequency.
  • Backplane Input/Output Allows Simple Synchronization of Slave-Devices to a Master.
  • ICM7211A Devices Provide Separate Digit Select Inputs to Accept Multiplexed BCD Input (Pinout and Functionally Compatible with Siliconix DF411).
  • ICM7211AM Devices Provide Data and Digit Address Latches Controlled by Chip Select.

ICM7211A August 2001 4-Digit, LCD Display Driver Description The ICM7211A (LCD) device constitutes a family of non-multiplexed four-digit seven-segment CMOS display decoderdrivers. The ICM7211A devices are configured to drive conventional LCD displays by providing a complete RC oscillator, divider chain, backplane driver, and 28 segment outputs. This device is available with multiplexed or microprocessor 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 ICL7135. The microprocessor versions provide data input latches and Digit Address latches under control of high-speed Chip Select inputs.
