SER7 IC Serial to Seven Segment Controller

General Description

The SER7 IC is a bridge between serial interfaces and one or two non-multiplexed seven segment displays. Data is received in a 32 byte buffer, and translated from ASCII to seven segment codes when a carriage return (Hex 0D) is received. More than one SER7 chip may be connected together to achieve up to 32 digits of display. The SER7 has internal pull resistors on most inputs to minimize additional parts. The SER7 may connect to RS-232, USB, RS-485, Ethernet or directly to your UART.

Features:

  • Drives one or two seven segment displays from serial data.
  • Converts from ASCII to seven segment codes.
  • Few external parts required.
  • Low power consumption 3 mA typical.
  • Supply voltage 2.4 to 5.25 volts.
  • All timing internally generated.
  • On chip input resistors.
  • Output polarity select.
  • Right or left hand decimal point displays.
  • Right or left display justification.
  • TTL and CMOS compatible outputs.
  • Part is in full production.
  • SOIC and DIP 28 Pin Package.
  • Low EMI.
  • ROHS Compliant.
