M74HC76B1R集成電路（IC）的觸發(fā)器規(guī)格書(shū)PDF中文資料

M74HC76B1R屬于集成電路（IC）的觸發(fā)器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的M74HC76B1R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(lèi)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。

DESCRIPTION

The M54/74HC76 is a high speed CMOSDUAL J-K FLIP FLOP fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. Depending on with the logic level at the J and K inputs this device changes state on the negative going transition of the clock pulse. CLEAR and PRESET are independent of the clock and are accomplished by a logic low on the corresponding input. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED fMAX = 65 MHz (TYP.) AT VCC = 5 V

■ LOW POWER DISSIPATION ICC = 2 μA (MAX.) AT 25 °C

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

■ SYMMETRICAL OUTPUT IMPEDANCE ?IOH? = IOL = 4 mA (MIN.)

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

■ HIGH NOISE IMMUNITY VNIH = VNIL = 28 VCC (MIN.)

■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS76
