SN74ABT5402A屬于集成電路（IC）的緩沖器驅動器接收器收發(fā)器。由美國德州儀器公司制造生產的SN74ABT5402A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

These 12-bit buffers and line drivers are designed

specifically to improve both the performance and

density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and

transmitters.

The 3-state control gate is a 2-input AND gate with

active-low inputs so that if either output-enable

(OE1 or OE2) input is high, all 12 outputs are in the

high-impedance state.

The outputs, which are designed to source or sink

up to 12 mA, include equivalent 25-W series

resistors to reduce overshoot and undershoot.

To ensure the high-impedance state during power

up or power down, OE should be tied to VCC

through a pullup resistor; the minimum value of

the resistor is determined by the current-sinking

capability of the driver.

The SN54ABT5402A is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74ABT5402A is characterized for operation from –40°C to 85°C.
