TI SN74HC393DR

Wide operating voltage range of 2V to 6V; output can drive up to 10 LSTTL loads; low power consumption: 80μA maximum ICC; typical tpd = 13ns; output drive of ±4mA at 5V; low input current, 1μA maximum; dual 4-bit binary counters with separate clocks; direct clear for each 4-bit counter; reduces counter package count by 50%, significantly improving system density. The HC393 device contains eight flip-flops and additional gating to implement two independent 4-bit counters in a single package.
