ICM7224 Datasheet 41/2 Digit Lcd Display Counter

Manufacturer: Intersil (now Renesas)

Overview: ® NO R May 2001 T ODUC T ETE PR PL ACEMEN L O S E OB R ED MEND EC O M ICM7224 4 1/2 Digit LCD Display.

General Description

The ICM7224 device is a high-performance, CMOS 41/2 digit counter, including decoder, output latch, display driver, count inhibit, leading zero blanking, and reset circuitry.

The counter section provides direct static counting, guaranteed from DC to 15MHz, using a 5V ±10% supply over the operating temperature range.

At normal ambient temperatures, the devices will typically count up to 25MHz.

Key Features

  • intended to simplify cascading four-digit blocks. The CARRY output allows the counter to be cascaded, while the Leading Zero Blanking INput and OUTput allows correct Leading Zero Blanking between four-decade blocks. The BackPlane driver of the LCD devices may be disabled, allowing the segments to be slaved to another backplane signal, necessary when using an eight or twelve digit, single backplane display. These devices provide maximum count of 19999. The display drivers are not of the multiplex.
