M74HCT240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

M74HCT240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M74HCT240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 74HCT240 is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with silicon gate C2MOS technology. G control input governs four BUS BUFFERs. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED:

tPD = 15 ns (TYP.) at VCC = 4.5V

■ LOW POWER DISSIPATION:

ICC = 4µA(MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS :

VIH = 2V (MIN.) VIL = 0.8V (MAX)

■ BALANCED PROPAGATION DELAYS:

tPLH ≅ tPHL

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 6mA (MIN)

■ PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 240
