74ACT16374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74ACT16374觸發(fā)器觸發(fā)器是能夠存儲單個(gè)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(gè)輸入；一個(gè)或多個(gè)用于傳遞要存儲的數(shù)據(jù)，另一個(gè)用于指示存儲該數(shù)據(jù)的時(shí)間點(diǎn)。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(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)鐘信號時(shí)才會改變。

DESCRIPTION

The 74ACT16374 is an advanced high-speed CMOS 16-BIT D-TYPE FLIP-FLOP (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology.

This 16 bit D-Type Flip-Flop is controlled by two clock inputs (CK) and two output enable inputs (OE). The device can be used as two 8-bit flip-flops or one 16-bit flip-flop.

On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs.

While the (OE) input is low, the outputs will be in a normal logic state (high or low logic level); while OE is high, the outputs will be in a high impedance state.

The output control does not affect the internal operation of flip-flops; that is, the old data can be retained or the new data can be entered even while the outputs are off.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED:

fMAX = 120MHz (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION:

ICC = 8μA(MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS

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

■ 50? TRANSMISSION LINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 24mA (MIN)

■ OPERATING VOLTAGE RANGE:

VCC (OPR) = 4.5V to 5.5V

■ IMPROVED LATCH-UP IMMUNITY
