AS YOU KNOW, ELECTRON BECOME THE MOST IMPORTANT PART IN DAILY LIFE. SO, IF YOU WANT IC, WILL YOU CONSIDER A BETTER PRODUCT IN LOWER PRICE. I RECOMMEND A WEB CALLED [url]http://www.chinaicmart.com [/url]WHICH MAY BE USEFUL FOR YOU.
HERE IS AN EXAMPLE FOR YOU TO REFER.
PRODUCT:IC74ABTH16821ADGG(FROM:http://www.chinaicmart.com/series-74A/74ABTH16821ADGG.html)
DESCRIPTION
The 74ABT16821A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74ABT16821A has two 10-bit, edge triggered registers, with each register coupled to a 3-State output buffer. The two sections of each register are controlled independently by the clock (nCP) and Output Enable (nOE) control gates.
Each register is fully edge triggered. The state of each D input, one set-up time before the Low-to-High clock transition, is transferred to the corresponding flip-flop! The 3-State output buffers are designed to drive heavily loaded 3-State buses, MOS memories, or MOS microprocessors.
The active Low Output Enable (nOE) controls all ten 3-State buffers is Low, the data in independent of the register operation. When nOE the register appears at the outputs. When nOE is High, the outputs are in high impedance !off!– state, which means they will neither dri nor load the bus.
Two options are available, 74ABT16821A which does not have the bus-hold feature and 74ABTH16821A which incorporates the bus-hold feature. | |
