M5480
DESCRIPTION
DIP-28 (Plastic Package) ORDER CODE : M5480B7
The M5480 is a monolithic MOS integrated circuit produced with a N-channel silicon gate technology. It utilizes the M5451 die packaged in a 28-pin plas-tic package making it ideal for a 3 1/2 digit dispaly. A single pin controls the LED dispaly brightness by setting a reference current through a variable resistor connected either to VDD or to a separate supply of 13.2V maximum. The M5480 is a pin-to-pin replacement of the NS MM 5480. PIN CONNECTIONS
