SN74HC393N, Два 4-битных двоичных счетчика, [DIP-14]
The SN74HC393N is a dual 4-bit Binary Counter has parallel outputs from each counter stage so that any sub-multiple of the input count frequency is available for system timing signals. The HC393 device contains eight flip-flops and additional gating to implement two individual 4-bit counters. This device comprises two independent 4-bit binary counters each having a clear (CLR) and a clock (CLK) input. N-bit binary counters can be implemented providing the capability of divide by 256.
• Outputs can drive up to 10 LSTTL loads
• Direct clear for each 4-bit counter
• Green product and no Sb/Br
