CD4516 Binary Up Down Counter – Datasheet

CD4516 Presettable Binary Up/Down counter consists of four synchronously clocked D-type flip-flops connected as counters. These counters can be cleared by a high level on the RESET line and can be preset to any binary number present on the jam inputs by a high level on the PE line. Synchronous cascading is accomplished by connecting all clock inputs in parallel and connecting the CARRY OUT of a less significant stage to the CARRY IN of a more significant stage.
The IC can be cascaded in the ripple mode by connecting the CARRY OUT to the clock of the next stage. If the UP/DOWN input changes during a terminal count, the CARRY OUT must be gated with the clock, and the UP/DOWN input must change while the clock is high. The IC is always available in 16 – pin hermetically sealed package and is directly interfaceable with every TTL, CMOS & NMOS device.

Binary Up/Down Counter

A binary up/down counter is a simple digital logic configuration that can count immediate as well as subsequent events in an increasing as well as decreasing order. For example a 4-bit binary up/down counter can count from 0000 to 1111 and also from 1111 to 0000. A simple Binary up/down counter can easily be made by rigging at least two D – type flip flops. A 4 bit binary counter will act as a decade counter by skipping any six outputs out of the 16 (24) outputs.
