MC74VHCT50ADR2G集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

MC74VHCT50ADR2G属于集成电路（IC）的缓冲器驱动器接收器收发器。由安森美半导体制造生产的MC74VHCT50ADR2G缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。

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.
