描述 Description

High Performance Silicon Gate CMOS The MC74HC112A is identical in pinout to the LS112. The device inputs are compatible with standard CMOS outputs, with pullup resistors, they are compatible with LSTTL outputs. Each flip flop is negative edge clocked and has active low asynchronous Set and Reset inputs. The HC112A is identical in function to the HC76, but has a different pinout.

特性 Features

? Output Drive Capability: 10 LSTTL Loads
? Outputs Directly Interface to CMOS, NMOS, and TTL
? Operating Voltage Range: 2.0 to 6.0 V
? Low Input Current: 1.0 A
? High Noise Immunity Characteristic of CMOS Devices
? In Compliance with the Requirements Defined by JEDEC Standard No. 7A
? Similar in Function to the LS112 Except When Set and Reset are Low Simultaneously
? Chip Complexity: 100 FETs or 25 Equivalent Gates
? PbFree Packages are Available

簡介

MC74HC112A屬于集成電路（IC）的觸發(fā)器。由制造生產(chǎn)的MC74HC112A觸發(fā)器觸發(fā)器是能夠存儲單個邏輯狀態(tài)或信息“位”的基本數(shù)字存儲器件。這些器件至少有兩個輸入；一個或多個用于傳遞要存儲的數(shù)據(jù)，另一個用于指示存儲該數(shù)據(jù)的時間點。不同的觸發(fā)器類型，例如 D（延遲）、SR（置位復(fù)位）和 JK，對提供給其輸入的信號有不同的響應(yīng)，可用于實現(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)僅在接收到有效時鐘信號時才會改變。
