二进制计数器23 V ~ 18 V

Overview

CD4518 Dual BCD Up-Counter and CD4520 Dual Binary Up-Counter each consist of two identical, internally synchronous4-stage counters. The counter stages are D-type flip-flops having interchangeable CLOCK and ENABLE lines for incrementingon either the positive-going or negative-going transition. For single-unit operation the ENABLE input is maintained highand the counter advances on each positive-going transition of the CLOCK. The counters are cleared by high levels on theirRESET lines.

The CD4518B and CD4520BCWMX 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 (M, M96, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
