Part #: 74163. Download. File Size: 756Kbytes. Page: 23 Pages. Description: SYNCHRONOUS 4-BIT COUNTERS. Manufacturer: Texas Instruments.

This synchronous, presettable, 4-bit binary counter has internal carry look-ahead circuitry for use in high-speed counting designs. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when. so instructed by the count-enable (ENP, ENT) inputs and internal gating.

从74163功能表的第一行我们可以发现，低电平有效的清零信号(clr非)必须由时钟clk的上升沿触发，才能起到清零左作用。 因此我们把这种清零方式称为同步清零。

2016年11月22日 · 因此，硬件工程师根据设计中常用的电路设计了163计数器，本节内容首先介绍74LS163的基本功能，然后以163为基础设计一个分频器和一个2421码模8电路（重点讲设计思路，verilog程序请自行完成）。 74LS163计数器有5个控制端、4个数据输入端和5个输出端，其逻辑功能和对应的逻辑符号如下图1和图2所示： RCO表示进位，其语义为：当从0000~1111计满一轮，并且ENT为1时，RCO为1，其它时候均为0. 由图1，74LS163具有置位、保持、加1计数等 …

The AC/ACT163 are high-speed synchronous modulo-16 binary counters. They are synchronously presettable for application in programmable dividers and have two types of Count Enable inputs plus a Terminal Count output for versatility in …

These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting designs. The '160/162/LS160A/LS162A, and 'S162 are decade counters and the '161/163/LS161A/LS163A, and 'S163 are 4-bit binary counters.
