The MM54C48 is a BCD-to-7 Segment Decoder produced by National Semiconductor Corporation. It has a wide supply voltage range (3.0V to 15V), guaranteed noise margin (1.0V), high noise immunity (0.45 VCC (typ)), low power fan out of 2 TTL compatibility driving 74L, high current sourcing output (up to 50 mA), Leading or Trailing zeros Ripple blanking (optional) and Lamp test provision.
This document is a datasheet for the MM54C48 and MM74C48 monolithic complementary MOS (CMOS) integrated circuits. These devices function as BCD-to-7 segment decoders with built-in drivers for driving seven decoding AND-OR-INVERT gates. The chips feature a wide supply voltage range from 3.0V to 15V and include provisions for ripple blanking and lamp testing.
