General Description

The CD4020BC, CD4060BC are 14-stage ripple carry binary counters, an d the CD4040BC is a 12-stage rip ple carry binary counter. The counters are advanced one count on the negative transition of each clock pulse. The

counters are reset to the zero state by a logical “1” at the reset input independent of clock.

Features

■ Wide supply voltage range: 1.0V to 15V

■ High noise immunity: 0.45 V

(typ.)

■ Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LS

■ Medium speed operation: 8 MHz typ. at V

= 10V

■ Schmitt trigger clock input

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to t he ordering code.
