General Description

The MM54HC4020 MM74HC4020 MM54HC4040 MM74HC4040 are high speed binary ripple carry counters These counters are implemented utilizing advanced silicongate CMOS technology to achieve speed performance similar to LS-TTL logic while retaining the low power and high noise immunity of CMOS The ’HC4020 is a 14 stage counter and the ’HC4040 is a 12stage counter Both devices are incremented on the falling edge (negative transition) of the input clock and all their outputs are reset to a low level by applying a logical high on their reset input These devices are pin equivalent to the CD4020 and CD4040 respectively All inputs are protected from damage due to static discharge by protection diodes to VCC and ground
