产品概述
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).
