74LVQ574T集成电路（IC）的锁存器规格书PDF中文资料

74LVQ574T属于集成电路（IC）的锁存器。由意法半导体集团制造生产的74LVQ574T锁存器锁存器是类似于触发器的基本数字存储设备，但是不同之处在于，在锁存使能（或类似命名）信号处于有效逻辑状态的任何时间，保持的逻辑状态都可以改变。“透明”锁存器还允许设备输出在锁存使能信号有效时反映输入的当前状态，而相反的是，状态仅在保持状态已固定时改变。

DESCRIPTION

The 74LVQ574 is a low voltage CMOS OCTAL D-TYPE FLIP-FLOP with 3 STATE OUTPUTS NON INVERTING 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.

■ HIGH SPEED:

fMAX = 180 MHz (TYP.) at VCC = 3.3V

■ COMPATIBLE WITH TTL OUTPUTS

■ LOW POWER DISSIPATION:

ICC = 4 µA (MAX.) at TA=25°C

■ LOW NOISE:

VOLP = 0.5V (TYP.) at VCC = 3.3V

■ 75Ω TRANSMISSION LINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 12mA (MIN) at VCC = 3.0V

■ PCI BUS LEVELS GUARANTEED AT 24 mA

■ BALANCED PROPAGATION DELAYS:

tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE:

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

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 574

■ IMPROVED LATCH-UP IMMUNITY
