DESCRIPTION

The M74HCT174 is an high speed CMOS HEX D-TYPE FLIP FLOP WITH CLEAR fabricated with silicon gate C2MOS technology.

Information signals applied to D inputs are transferred to the Q output on the positive going edge of the CLOCK (CK) pulse. When the CLEAR (CLR) input is held low, the Q outputs are held low independently of the other inputs.

All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED :

fMAX = 56MHz (TYP.) at VCC = 4.5V

■ LOW POWER DISSIPATION:

ICC =4µA(MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS :

VIH = 2V (MIN.) VIL = 0.8V (MAX)

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 4mA (MIN)

■ BALANCED PROPAGATION DELAYS:

tPLH ≅ tPHL

■ PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 174

M74HCT174属于集成电路（IC） > 触发器。意法半导体（ST）集团制造生产的M74HCT174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。
