74LVQ245T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

74LVQ245T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74LVQ245T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 LVQ245 is a low voltage CMOS OCTAL BUS TRANSCEIVER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and low noise 3.3V applications.

It has better speed performance at 3.3V than 5V LSTTL family combined with the true CMOS low power consumption.

■ HIGH SPEED: tPD = 6 ns (TYP.) at VCC = 3.3V

■ COMPATIBLEWITH TTL OUTPUTS

■ LOW POWER DISSIPATION:

ICC =5 µA (MAX.) at TA = 25 °C

■ LOW NOISE: VOLP = 0.5V(TYP.) at VCC = 3.3V

■ 75Ω TRANSMISSIONLINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 12 mA (MIN)

■ PCI BUS LEVELSGUARANTEED AT 24mA

■ BALANCEDPROPAGATIONDELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGERANGE:

VCC (OPR)= 2V to 3.6V (1.2VData Retention)

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 245

■ IMPROVED LATCH-UP IMMUNITY
