MM54C93 Datasheet 4-bit Binary Counter

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: MM54C90 MM74C90 4-Bit Decade Counter MM54C93 MM74C93 4-Bit Binary Counter February 1988 MM54C90 MM74C90 4-Bit Decade Counter MM54C93 MM74C93 4-Bit Binary Counter.

General Description

The MM54C90 MM74C90 decade counter and the MM54C93 MM74C93 binary counter and plementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement mode transistors The 4-bit decade counter can reset to zero or preset to nine by applying appropriate logic level on the R01 R02 R91 and R92 inputs Also a separate flip-flop on the A-bit enables the user to operate it as a divide-by-2 5 or 10 frequency counter The 4-bit binary counter can be reset to zero by applying high logic level on inputs R01 and R02 and a separate flip-flop on the A-bit enables the user to operate it as a divide-by-2 -8 or -16 divider Counting occurs on the negative going edge of the input pulse All inputs are protected against static discharge damage

Key Features

  • Y Wide supply voltage range Y Guaranteed noise margin.
