SNx4HC393 Dual 4-Bit Binary Counters

1 Features

• Wide operating voltage range of 2V to 6V

• Outputs can drive up to 10 LSTTL loads

• Low power consumption: 80μA max ICC

• Typical tpd = 13ns

• ±4mA output drive at 5V

• Low input current of 1μA max

• Dual 4-bit binary counters with individual clocks

• Direct clear for each 4-bit counter

• Can significantly improve system densities by

reducing counter package count by 50%

2 Description

The ’HC393 devices contain eight flip-flops and

additional gating to implement two individual 4-bit

counters in a single package.
