Description

T = 25 C

The Harris CD74HC4020 and CD74HCT4020 are 14-stage

ripple-carry binary counters. All counter stages are master-

slave ﬂip-ﬂops. The state of the stage advances one count

on the negative clock transition of each input pulse; a high

voltage level on the MR line resets all counters to their zero

state. All inputs and outputs are buffered.

• Fanout (Over Temperature Range)

- Standard Outputs. . . . . . . . . . . . . . . 10 LSTTL Loads
