74LCX125TTR集成電路（IC）的緩沖器驅動器接收器收發(fā)器規(guī)格書PDF中文資料

74LCX125TTR屬于集成電路（IC）的緩沖器驅動器接收器收發(fā)器。由意法半導體集團制造生產的74LCX125TTR緩沖器，驅動器，接收器，收發(fā)器邏輯緩沖器、驅動器、接收器和收發(fā)器允許隔離對某個電路的邏輯信號的訪問，以用于另一電路。緩沖器將其輸入信號（不變或反相）傳遞到其輸出，并可能用于清除弱信號或驅動負載。在布爾邏輯仿真器中，緩沖器主要用于增加傳播延遲。邏輯接收器和收發(fā)器允許在數據總線之間進行隔離通信。

Description

The 74LCX125 device is a low-voltage CMOS

quad bus buffer manufactured with sub-micron

silicon gate and double-layer metal wiring C2MOS

technology. It is ideal for low-power and highspeed

3.3 V applications and can be interfaced to

a 5 V signal environment for both inputs and

outputs.

The device requires the 3-state control input G to

be set high to place the output in the high

impedance state.

It has the same speed performance at 3.3 V as

the 5 V AC/ACT family, combined with lower

power consumption.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2 kV ESD immunity and transient excess

voltage.
