描述 Description

The MC74LCX16374 is a high performance, non-inverting 16-bit D-type flip-flop operating from a 2.3 to 3.6V supply. The device is byte controlled. Each byte has separate Output Enable and Clock Pulse inputs. These control pins can be tied together for full 16-bit operation.High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5V allows MC74LCX16374 inputs to be safely driven from 5V devices.The MC74LCX16374 consists of 16 edge-triggered flip-flops with individual D-type inputs and 5V-tolerant 3-state true outputs. The buffered clocks (CPn) and buffered Output Enables (OEnbar) are common to all flip-flops within the respective byte. The flip-flops will store the state of individual D inputs that meet the setup and hold time requirements on theLOW-to-HIGH Clock (CP) transition. With the OEbar LOW, the contents ofthe flip-flops are available at the outputs. When the OEbar is HIGH, the outputs go to the high impedance state. The OEbar input level does not affect the operation of the flip-flops.

簡(jiǎn)介

MC74LCX16374屬于集成電路（IC）的觸發(fā)器。由制造生產(chǎn)的MC74LCX16374觸發(fā)器觸發(fā)器是能夠存儲(chǔ)單個(gè)邏輯狀態(tài)或信息“位”的基本數(shù)字存儲(chǔ)器件。這些器件至少有兩個(gè)輸入；一個(gè)或多個(gè)用于傳遞要存儲(chǔ)的數(shù)據(jù)，另一個(gè)用于指示存儲(chǔ)該數(shù)據(jù)的時(shí)間點(diǎn)。不同的觸發(fā)器類型，例如 D（延遲）、SR（置位復(fù)位）和 JK，對(duì)提供給其輸入的信號(hào)有不同的響應(yīng)，可用于實(shí)現(xiàn)不同的邏輯功能。這些器件與鎖存器的不同之處在于它們是邊緣敏感器件，其保持的邏輯狀態(tài)僅在接收到有效時(shí)鐘信號(hào)時(shí)才會(huì)改變。
