M74HC4050B1R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

M74HC4050B1R属于集成电路（IC）的缓冲器驱动器接收器收发器。由意法半导体集团制造生产的M74HC4050B1R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。

DESCRIPTION

The M54/74HC4049 and the M54/74HC4050 are high speed CMOS HEX BUFFER fabricated in silicon gate C2MOS technology.

They have the same high speed performance of LSTTL combined with true CMOS low power consumption. The M54/75HC4049 is an inverting buffer, while the M54/74HC4050 is a non-inverting buffer.

The internal circuit is composed of 3 stage or 2- stage inverters, which provides high noise immunity and a stable output.

Input protection circuits are different from those of the high speed CMOS IC’s.

■ HIGH SPEED tPD = 9 ns (TYP.) AT VCC = 5 V

■ LOW POWER DISSIPATION ICC = 1 µA (MAX.) AT TA = 25 °C

■ HIGH NOISE IMMUNITY VNIH = VNIL = 28 VCC (MIN.)

■ OUTPUT DRIVE CAPABILITY 15 LSTTL LOADS

■ SYMMETRICAL OUTPUT IMPEDANCE |IOH| = IOL = 6 mA (MIN.)

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V

■ PIN AND FUNCTION COMPATIBLE WITH 4049B/4050B
