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

M74HC76B1R属于集成电路（IC） > 触发器。意法半导体（ST）集团制造生产的M74HC76B1R触发器触发器是能够存储单个逻辑状态或信息“位”的基本数字存储器件。这些器件至少有两个输入；一个或多个用于传递要存储的数据，另一个用于指示存储该数据的时间点。不同的触发器类型，例如 D（延迟）、SR（置位复位）和 JK，对提供给其输入的信号有不同的响应，可用于实现不同的逻辑功能。这些器件与锁存器的不同之处在于它们是边缘敏感器件，其保持的逻辑状态仅在接收到有效时钟信号时才会改变。
