MC74VHCT50A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

MC74VHCT50A屬于集成電路（IC）的緩沖器驅動器接收器收發(fā)器。由安森美半導體公司制造生產(chǎn)的MC74VHCT50A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(shù)據(jù)總線之間進行隔離通信。

The MC74VHCT50A is a hex noninverting buffer fabricated with

silicon gate CMOS technology. It achieves high speed operation

similar to equivalent Bipolar Schottky TTL while maintaining CMOS

low power dissipation.

The internal circuit is composed of three stages, including a buffered

output which provides high noise immunity and stable output.

The device input is compatible with TTL?type input thresholds and

the output has a full 5 V CMOS level output swing. The input protection

circuitry on this device allows overvoltage tolerance on the input,

allowing the device to be used as a logic?level translator from 3.0 V

CMOS logic to 5.0 V CMOS Logic or from 1.8 V CMOS logic to 3.0 V

CMOS Logic while operating at the high?voltage power supply.

The MC74VHCT50A input structure provides protection when

voltages up to 7 V are applied, regardless of the supply voltage. This

allows the MC74VHCT50A to be used to interface 5 V circuits to 3 V

circuits. The output structures also provide protection when

VCC = 0 V. These input and output structures help prevent device

destruction caused by supply voltage ? input/output voltage mismatch,

battery backup, hot insertion, etc.
