CD4040BE General Description

The CD4040BE is a 12-stage binary counter/divider IC with a built-in ripple-carry output. It can be used to count binary pulses and divide frequencies. The device can be configured to divide by various powers of 2.

CD4020B, CD4024B, and CD4040B are ripple-carry binary counters. All counter stages are master-slave flip-flops. The state of a counter advances one count on the negative transition of each input pulse; a high level on the RESET line resets thecounter to its all zeros state. Schmitt trigger action on the input-pulse line permits unlimited rise and fall times. All inputs and outputs are buffered.

The CD4020B and CD4040B 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 CD4040B type also is supplied in 16-lead small-outline packages (M and M96 suffixes).

The CD4024B types are supplied in 14-lead hermetic dual-in-line ceramic packages (F3A suffix), 14-lead dual-in-line plastic packages (E suffix), 14-lead small-outline packages (M, MT, M96, and NSR suffixes), and 14-lead thin shrink small-outline packages (PW and PWR suffixes).

Application

Frequency Division: The IC is often used to divide high-frequency signals to obtain lower-frequency outputs, which can be used in clock generation and timing applications.
Digital Counting: It's used in digital counting applications, such as counters for industrial automation, event counting, and timer circuits.
Sequencing: The CD4040BE can be used to create sequences of digital states or control the operation of sequential devices.
Frequency Synthesis: In applications that require synthesizing specific frequencies by dividing or counting a reference clock source.
Pulse Generation: It can be used to generate sequences of pulses with controlled durations and intervals.
Timing and Delay Generation: In applications that require precise timing or delay generation.
