MC74HC174AN集成電路（IC）的觸發(fā)器規(guī)格書PDF中文資料

MC74HC174AN屬于集成電路（IC）的觸發(fā)器。由安森美半導體公司制造生產的MC74HC174AN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，另一個用于指示存儲該數(shù)據的時間點。不同的觸發(fā)器類型，例如 D（延遲）、SR（置位復位）和 JK，對提供給其輸入的信號有不同的響應，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。

Hex D Flip?Flop with Common Clock and Reset

High–Performance Silicon–Gate CMOS

The MC74HC174A is identical in pinout to the LS174. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

This device consists of six D flip–flops with common Clock and Reset inputs. Each flip–flop is loaded with a low–to–high transition of the Clock input. Reset is asynchronous and active–low.

? Output Drive Capability: 10 LSTTL Loads

? TTL NMOS Compatible Input Levels

? Outputs Directly Interface to CMOS, NMOS, and TTL

? Operating Voltage Range: 4.5 to 5.5 V

? Low Input Current: 1.0 μA

? In Compliance with the Requirements Defined by JEDEC Standard No. 7A

? Chip Complexity: 162 FETs or 40.5 Equivalent Gates
