CD4040 is ripple-carry binary counters. The IC 4040 is technically a 12-stage binary ripple counter chip, in simple words a device which will produce a calculated delayed frequency output in response to every pulse applied at its clock input. This delay is incremented at the rate of 2^(n) where n is the pinout order in the sequence of its outputs.

⁍The CD4040 types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (NSR suffix), and 16-lead thin shrink small-outline packages (PW and PWR suffixes). The CD4040 type also is supplied in 16-lead small-outline packages (M and M96 suffixes).

Features:

• Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LS
• Medium speed operation: 8 MHz typ. at V_DD = 10V
• Schmitt trigger clock input
• This is a Thru-Hole Device
