CMOS 24-Stage Frequency Divider

CD4521B consists of an Oscillator section and 24 ripple-carry binary Counter stages. The Oscillator configuration (using IN1) allows design of either RC or crystal Oscillator circuits. IN1 should be tied either HIGH or LOW when not in use. A HIGH on the RESET causes the Counter to go to the all-0?s state and disables the Oscillator The count is advanced on the negative transition of IN1 (and IN2). A time-saving test mode is described in the Functional Test Sequence Table and in Fig. 6.
The CD4521B types are supplied in 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
