| MM74C93 4-Bit Binary Counter MM74C93 4-Bit Binary Counter The MM74C93 binary counter and complementary MOS CMOS integrated circuits constructed with N- and Pchannel enhancement mode transistors. 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. s Wide supply voltage range 3V to 15V s Guaranteed noise margin 1V s High noise immunity VCC typ. s Low power compatibility: Fan out of 2 TTL driving 74L s The MM74C93 follows the MM74L93 Pinout Ordering Code: Order Number MM74C93N Package Number Package Description N14A 14-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-001, Wide Connection Diagram Top View Logic Diagram Truth Table 4-Bit Binary Counter Binary Count Sequence Count Output QD QC QB QA LHLH L HH L L HHH HLHL HLHH HH L H HHH L HHHH Output QA is connected to input B for binary count sequence.
