產品概述
The SN74HC393D is a 4-bit dual Binary Counter contains eight flip-flops and additional gating to implement two individual 4-bit counters in a single package. It comprises two independent 4-bit binary counters, each having a clear (CLR) and a clock input. N-bit binary counters can be implemented with each package, providing the capability of divide by 256. It has parallel outputs from each counter stage so that any submultiple of the input count frequency is available for system timing signals.
Outputs can drive up to 10 LSTTL loads
Direct clear for each 4-bit counter
80μA Maximum low power consumption
13ns TypICal tpd
±4mA Output drive at 5V
1μA Maximum low input current
Green product and no Sb/Br
